How to Write a Literary Analysis Essay | A Step-by-Step Guide

Published on January 30, 2020 by Jack Caulfield . Revised on August 14, 2023.

Literary analysis means closely studying a text, interpreting its meanings, and exploring why the author made certain choices. It can be applied to novels, short stories, plays, poems, or any other form of literary writing.

A literary analysis essay is not a rhetorical analysis , nor is it just a summary of the plot or a book review. Instead, it is a type of argumentative essay where you need to analyze elements such as the language, perspective, and structure of the text, and explain how the author uses literary devices to create effects and convey ideas.

Before beginning a literary analysis essay, it’s essential to carefully read the text and c ome up with a thesis statement to keep your essay focused. As you write, follow the standard structure of an academic essay :

• An introduction that tells the reader what your essay will focus on.
• A main body, divided into paragraphs , that builds an argument using evidence from the text.
• A conclusion that clearly states the main point that you have shown with your analysis.

Step 1: reading the text and identifying literary devices, step 2: coming up with a thesis, step 3: writing a title and introduction, step 4: writing the body of the essay, step 5: writing a conclusion, other interesting articles.

The first step is to carefully read the text(s) and take initial notes. As you read, pay attention to the things that are most intriguing, surprising, or even confusing in the writing—these are things you can dig into in your analysis.

Your goal in literary analysis is not simply to explain the events described in the text, but to analyze the writing itself and discuss how the text works on a deeper level. Primarily, you’re looking out for literary devices —textual elements that writers use to convey meaning and create effects. If you’re comparing and contrasting multiple texts, you can also look for connections between different texts.

To get started with your analysis, there are several key areas that you can focus on. As you analyze each aspect of the text, try to think about how they all relate to each other. You can use highlights or notes to keep track of important passages and quotes.

Language choices

Consider what style of language the author uses. Are the sentences short and simple or more complex and poetic?

What word choices stand out as interesting or unusual? Are words used figuratively to mean something other than their literal definition? Figurative language includes things like metaphor (e.g. “her eyes were oceans”) and simile (e.g. “her eyes were like oceans”).

Also keep an eye out for imagery in the text—recurring images that create a certain atmosphere or symbolize something important. Remember that language is used in literary texts to say more than it means on the surface.

Narrative voice

Ask yourself:

• Who is telling the story?
• How are they telling it?

Is it a first-person narrator (“I”) who is personally involved in the story, or a third-person narrator who tells us about the characters from a distance?

Consider the narrator’s perspective . Is the narrator omniscient (where they know everything about all the characters and events), or do they only have partial knowledge? Are they an unreliable narrator who we are not supposed to take at face value? Authors often hint that their narrator might be giving us a distorted or dishonest version of events.

The tone of the text is also worth considering. Is the story intended to be comic, tragic, or something else? Are usually serious topics treated as funny, or vice versa ? Is the story realistic or fantastical (or somewhere in between)?

Consider how the text is structured, and how the structure relates to the story being told.

• Novels are often divided into chapters and parts.
• Poems are divided into lines, stanzas, and sometime cantos.
• Plays are divided into scenes and acts.

Think about why the author chose to divide the different parts of the text in the way they did.

There are also less formal structural elements to take into account. Does the story unfold in chronological order, or does it jump back and forth in time? Does it begin in medias res —in the middle of the action? Does the plot advance towards a clearly defined climax?

With poetry, consider how the rhyme and meter shape your understanding of the text and your impression of the tone. Try reading the poem aloud to get a sense of this.

In a play, you might consider how relationships between characters are built up through different scenes, and how the setting relates to the action. Watch out for  dramatic irony , where the audience knows some detail that the characters don’t, creating a double meaning in their words, thoughts, or actions.

Prevent plagiarism. Run a free check.

Your thesis in a literary analysis essay is the point you want to make about the text. It’s the core argument that gives your essay direction and prevents it from just being a collection of random observations about a text.

If you’re given a prompt for your essay, your thesis must answer or relate to the prompt. For example:

Essay question example

Is Franz Kafka’s “Before the Law” a religious parable?

Your thesis statement should be an answer to this question—not a simple yes or no, but a statement of why this is or isn’t the case:

Thesis statement example

Franz Kafka’s “Before the Law” is not a religious parable, but a story about bureaucratic alienation.

Sometimes you’ll be given freedom to choose your own topic; in this case, you’ll have to come up with an original thesis. Consider what stood out to you in the text; ask yourself questions about the elements that interested you, and consider how you might answer them.

Your thesis should be something arguable—that is, something that you think is true about the text, but which is not a simple matter of fact. It must be complex enough to develop through evidence and arguments across the course of your essay.

Say you’re analyzing the novel Frankenstein . You could start by asking yourself:

Your initial answer might be a surface-level description:

The character Frankenstein is portrayed negatively in Mary Shelley’s Frankenstein .

However, this statement is too simple to be an interesting thesis. After reading the text and analyzing its narrative voice and structure, you can develop the answer into a more nuanced and arguable thesis statement:

Mary Shelley uses shifting narrative perspectives to portray Frankenstein in an increasingly negative light as the novel goes on. While he initially appears to be a naive but sympathetic idealist, after the creature’s narrative Frankenstein begins to resemble—even in his own telling—the thoughtlessly cruel figure the creature represents him as.

Remember that you can revise your thesis statement throughout the writing process , so it doesn’t need to be perfectly formulated at this stage. The aim is to keep you focused as you analyze the text.

Finding textual evidence

To support your thesis statement, your essay will build an argument using textual evidence —specific parts of the text that demonstrate your point. This evidence is quoted and analyzed throughout your essay to explain your argument to the reader.

It can be useful to comb through the text in search of relevant quotations before you start writing. You might not end up using everything you find, and you may have to return to the text for more evidence as you write, but collecting textual evidence from the beginning will help you to structure your arguments and assess whether they’re convincing.

To start your literary analysis paper, you’ll need two things: a good title, and an introduction.

Your title should clearly indicate what your analysis will focus on. It usually contains the name of the author and text(s) you’re analyzing. Keep it as concise and engaging as possible.

A common approach to the title is to use a relevant quote from the text, followed by a colon and then the rest of your title.

If you struggle to come up with a good title at first, don’t worry—this will be easier once you’ve begun writing the essay and have a better sense of your arguments.

“Fearful symmetry” : The violence of creation in William Blake’s “The Tyger”

The introduction

The essay introduction provides a quick overview of where your argument is going. It should include your thesis statement and a summary of the essay’s structure.

A typical structure for an introduction is to begin with a general statement about the text and author, using this to lead into your thesis statement. You might refer to a commonly held idea about the text and show how your thesis will contradict it, or zoom in on a particular device you intend to focus on.

Then you can end with a brief indication of what’s coming up in the main body of the essay. This is called signposting. It will be more elaborate in longer essays, but in a short five-paragraph essay structure, it shouldn’t be more than one sentence.

Mary Shelley’s Frankenstein is often read as a crude cautionary tale about the dangers of scientific advancement unrestrained by ethical considerations. In this reading, protagonist Victor Frankenstein is a stable representation of the callous ambition of modern science throughout the novel. This essay, however, argues that far from providing a stable image of the character, Shelley uses shifting narrative perspectives to portray Frankenstein in an increasingly negative light as the novel goes on. While he initially appears to be a naive but sympathetic idealist, after the creature’s narrative Frankenstein begins to resemble—even in his own telling—the thoughtlessly cruel figure the creature represents him as. This essay begins by exploring the positive portrayal of Frankenstein in the first volume, then moves on to the creature’s perception of him, and finally discusses the third volume’s narrative shift toward viewing Frankenstein as the creature views him.

Some students prefer to write the introduction later in the process, and it’s not a bad idea. After all, you’ll have a clearer idea of the overall shape of your arguments once you’ve begun writing them!

If you do write the introduction first, you should still return to it later to make sure it lines up with what you ended up writing, and edit as necessary.

The body of your essay is everything between the introduction and conclusion. It contains your arguments and the textual evidence that supports them.

Paragraph structure

A typical structure for a high school literary analysis essay consists of five paragraphs : the three paragraphs of the body, plus the introduction and conclusion.

Each paragraph in the main body should focus on one topic. In the five-paragraph model, try to divide your argument into three main areas of analysis, all linked to your thesis. Don’t try to include everything you can think of to say about the text—only analysis that drives your argument.

In longer essays, the same principle applies on a broader scale. For example, you might have two or three sections in your main body, each with multiple paragraphs. Within these sections, you still want to begin new paragraphs at logical moments—a turn in the argument or the introduction of a new idea.

Robert’s first encounter with Gil-Martin suggests something of his sinister power. Robert feels “a sort of invisible power that drew me towards him.” He identifies the moment of their meeting as “the beginning of a series of adventures which has puzzled myself, and will puzzle the world when I am no more in it” (p. 89). Gil-Martin’s “invisible power” seems to be at work even at this distance from the moment described; before continuing the story, Robert feels compelled to anticipate at length what readers will make of his narrative after his approaching death. With this interjection, Hogg emphasizes the fatal influence Gil-Martin exercises from his first appearance.

Topic sentences

To keep your points focused, it’s important to use a topic sentence at the beginning of each paragraph.

A good topic sentence allows a reader to see at a glance what the paragraph is about. It can introduce a new line of argument and connect or contrast it with the previous paragraph. Transition words like “however” or “moreover” are useful for creating smooth transitions:

… The story’s focus, therefore, is not upon the divine revelation that may be waiting beyond the door, but upon the mundane process of aging undergone by the man as he waits.

Nevertheless, the “radiance” that appears to stream from the door is typically treated as religious symbolism.

This topic sentence signals that the paragraph will address the question of religious symbolism, while the linking word “nevertheless” points out a contrast with the previous paragraph’s conclusion.

Using textual evidence

A key part of literary analysis is backing up your arguments with relevant evidence from the text. This involves introducing quotes from the text and explaining their significance to your point.

It’s important to contextualize quotes and explain why you’re using them; they should be properly introduced and analyzed, not treated as self-explanatory:

It isn’t always necessary to use a quote. Quoting is useful when you’re discussing the author’s language, but sometimes you’ll have to refer to plot points or structural elements that can’t be captured in a short quote.

In these cases, it’s more appropriate to paraphrase or summarize parts of the text—that is, to describe the relevant part in your own words:

The conclusion of your analysis shouldn’t introduce any new quotations or arguments. Instead, it’s about wrapping up the essay. Here, you summarize your key points and try to emphasize their significance to the reader.

A good way to approach this is to briefly summarize your key arguments, and then stress the conclusion they’ve led you to, highlighting the new perspective your thesis provides on the text as a whole:

By tracing the depiction of Frankenstein through the novel’s three volumes, I have demonstrated how the narrative structure shifts our perception of the character. While the Frankenstein of the first volume is depicted as having innocent intentions, the second and third volumes—first in the creature’s accusatory voice, and then in his own voice—increasingly undermine him, causing him to appear alternately ridiculous and vindictive. Far from the one-dimensional villain he is often taken to be, the character of Frankenstein is compelling because of the dynamic narrative frame in which he is placed. In this frame, Frankenstein’s narrative self-presentation responds to the images of him we see from others’ perspectives. This conclusion sheds new light on the novel, foregrounding Shelley’s unique layering of narrative perspectives and its importance for the depiction of character.

Text analysis and writing analysis texts are important skills to develop as they allow individuals to critically engage with written material, understand underlying themes and arguments, and communicate their own ideas in a clear and effective manner. These skills are essential in academic and professional settings, as well as in everyday life, as they enable individuals to evaluate information and make informed decisions.

What is Text Analysis?

Text analysis is the process of examining and interpreting a written or spoken text to understand its meaning, structure, and context. It involves breaking down the text into its constituent parts, such as words, phrases, and sentences, and analyzing how they work together to convey a particular message or idea.

Text analysis can be used to explore a wide range of textual material, including literature, poetry, speeches, and news articles, and it is often employed in academic research, literary criticism, and media analysis. By analyzing texts, we can gain deeper insights into their meanings, uncover hidden messages and themes, and better understand the social and cultural contexts in which they were produced.

What is an Analysis Essay?

An analysis essay is a type of essay that requires the writer to analyze and interpret a particular text or topic. The goal of an analysis essay is to break down the text or topic into smaller parts and examine each part carefully. This allows the writer to make connections between different parts of the text or topic and develop a more comprehensive understanding of it.

In “The Yellow Wallpaper,” Charlotte Perkins Gilman uses the first-person point of view and vivid descriptions of the protagonist’s surroundings to convey the protagonist’s psychological deterioration. By limiting the reader’s understanding of the story’s events to the protagonist’s perspective, Gilman creates a sense of claustrophobia and paranoia, mirroring the protagonist’s own feelings. Additionally, the use of sensory language, such as the “smooch of rain,” and descriptions of the “yellow wallpaper” and its “sprawling flamboyant patterns,” further emphasize the protagonist’s sensory and emotional experience. Through these techniques, Gilman effectively communicates the protagonist’s descent into madness and the effects of societal oppression on women’s mental health.

There are several different types of analysis essays, including:

Literary Analysis Essays: These essays examine a work of literature and analyze various literary devices such as character development, plot, theme, and symbolism.

Rhetorical Analysis Essays: These essays examine how authors use language and rhetoric to persuade their audience, focusing on the author's tone, word choice, and use of rhetorical devices.

Visual Analysis Essays: These essays analyze visual art, such as paintings or sculptures, and explore how the artwork's elements work together to create meaning.

Historical Analysis Essays: These essays analyze historical events or documents and examine their causes, effects, and implications.

Comparative Analysis Essays: These essays compare and contrast two or more works, focusing on similarities and differences between them.

Process Analysis Essays: These essays explain how to do something or how something works, providing a step-by-step analysis of a process.

The Ultimate Guide to Analytical Essay Writing: How to Craft an A-Grade Paper?

25 January, 2021

17 minutes read

Author:  Kate Smith

An analytical essay is often considered the most challenging piece of writing. However, those who have dealt with it at least once are a step closer to calling themselves masters of essay writing. This type of paper requires plenty of analytical skills to carry out an in-depth analysis of the assigned topic. Yet, the main goal of an analytical essay is not only to demonstrate your ability to learn the basics of the theme.

You also need to think critically, analyze facts, express your standpoint, and clearly show a deep understanding of key concepts. In short, your main task as an author is to prove the validity of your views by coming up with strong arguments that do not beg any questions.

The given guide provides a full analytical essay definition, as well as specifies its features and structural aspects. The following information will help you properly start your paper, choose a relevant topic, and come up with compelling conclusions. 

What is an Analytical Essay?

An analytical essay is a piece of writing aimed to provide a thorough analysis of a definite phenomenon using persuasive arguments and supporting assertions. Analysis in the analytical essay writing process stands for a method of research that allows one to study specific features of an object. Analytical papers also have to do with analysis of a specific problem; that is consideration of the problem itself and identification of its key patterns. The subject matter of analysis can be a well-known or little-studied scientific phenomenon, artistic work, historical event, social problem, etc.

The content of an analytical essay will totally depend on the object that has been chosen for analysis. Thus, when shedding light on any kind of scientific work, an analytical essay can be devoted to the analysis of research credibility, its relevance, or the adequacy of conclusions. When considering a work of art, an essay writer can focus on the analysis of the author’s artistic techniques or issues raised in the book. For this reason, it is essential to accurately determine the topic and subject matter of your future analytical essay.

Steps to Take Before Writing

The preparational stage of analytical essay writing cannot be omitted. It lays the basis for the A-grade paper and should be carefully completed. If you don’t know how to start an analytical essay, read a few handy tips that will ensure a solid foundation for your paper.  

Define a subject matter

You first need to clearly understand the issue you will base your essay on. Since analytical essays imply an in-depth analysis of a specific problem, you need to define its core. Try to split the analysis into several components and provide arguments taken either from a book, a research, a scientific work, or a movie (depending on the subject matter of your analysis), and support your views comprehensively.

Decide on the content of your analytical essay

If you are a student who was given an analytical essay topic, read the task several times before you are 100% sure that you clearly understand the requirements as to the analytical essay format. In case you were lucky to choose the topic of the analytical paper by yourself, make sure the theme you will be dealing with is familiar or at least seems interesting to you. 

Remember that different subject matters require a different approach to their analysis. If you examine some literature work, you can prove your opinion based on the deeds of a certain or several characters. But if you have been assigned the task to elaborate on some historic events, analyze their main causes, driving forces that have affected their course, and their global consequences.  

Take care of the proper start

Don’t forget to start your analytical essay with a thesis statement. It is a sentence or a couple of sentences that aim to summarize the key statements of your paper. A thesis statement should provide readers with a preliminary idea of what your essay is all about.  

Find extra reasoning

Make sure your thesis is supported by compelling arguments. To find enough evidence, you should carry out a thorough analysis of the assigned topic. List the crucial points of your research and ponder over the ways they can be used to prove your final opinion. 

Elaborate the outline

A sound outline elaborated at the preparation stage will help you ensure a proper analytical essay structure and make the overall writing process easier. As a rule, an analytical essay consists of an introduction, three body paragraphs, and a conclusion. Your outline plan should include the key arguments you want to discuss in each paragraph. 

Analytical Essay Thesis

A thesis statement represents the central idea of your paper and must serve as strong proof of your standpoint. While elaborating your thesis statement, it is crucial to include it at the end of the first paragraph and thus set a direction for the overall paper.

An outline is not a required element of analytical essays writing and should not be included in the text, but it can greatly facilitate the whole process of paper writing.

The analytical essay structure looks as follows:

Introduction

In the introduction of an analytical essay, you will need to identify your paper’s subject matter. Mention the purpose of your work and specify its scope of research. Don’t forget to include a thesis to let readers know what your work is about.

Body Section

As has already been mentioned, the body section covers three or more main paragraphs, each being supported with arguments and details. Besides, you need to provide a small conclusion to each statement to make your essay sound professional and persuasive. 

At this stage, you need to summarize the points elucidated in your paper and make sure there is a smooth and logical transition from the body section to the concluding part of the text. If you don’t know how to conclude an analytical essay, try to restate the thesis statement without copying it word for word.

Main Tips for Writing an Analytical Essay

An analytical essay should provide a comprehensive analysis of a chosen topic. What makes an analysis essay different from other assignments is that it includes a personal opinion of an author. This is why analytical writing should be persuasive.

Below, we have rounded up the key tips you need to follow when producing an analytical essay outline and the main body of your text. Read on to learn more about the analytical essay format and create a text that will fully meet the requirements.

Select an Analytical Essay Topic

Before creating an analytical essay outline, make sure to pick a topic that you are interested in. It should be provocative enough to engage your readers. A widely-debated topic will help you write an analytical essay that grabs the attention of a wide audience.

Consider your goals and conduct thorough research to see if you have enough sources to support the main thesis of your analysis essay.

Come Up With a Strong Analytical Thesis Statement

When writing an analytical essay, start by formulating a thesis statement that includes the topic and the main goal of your text. It will help you create an analytical essay outline and show your readers what you will discuss in your analysis essay.

Add it to the last paragraph of your analytical essay introduction. Due to this, your analytical essay outline will look better structured. Look at any analytical essay example to see how you can introduce your subject. In most cases, one sentence will suffice to state your analysis essay’s goal. However, a complex analytical essay outline might require you to use two sentences for a thesis statement.

Write an Analytical Essay Body with a Clear Structure

Your analytical essay outline should include 3-4 paragraphs. However, a literary analysis essay usually consists of 5 paragraphs. When it comes to analytical writing, it is important to cover a different point in each section of the main body of an analysis paper.

After writing an analytical essay, check whether each paragraph contains an introduction and the main point. Besides, it should contain evidence. An expertly written analytical essay outline will help you reach out to your target audience more effectively.

Conduct Research Before Writing an Analytical Essay Outline

While this step is preparatory, it is a must for those who want to write a well-grounded analytical paper.

• First, select the best ideas for your essay
• Then, emphasize the problems with works written by other researchers
• Finally, write your analytical essay outline to demonstrate what approach you want to take

Examine the context and find examples to illustrate the scope of the issue. You may draw parallels to emphasize your point and make your topic more relatable.

Analyze the Implications of the Evidence

After listing your pieces of evidence and demonstrating how it is related to your thesis, show why it is important. You need to explore it deeply and use it to support your argument. It will make your analytical essay outline well-grounded facts.

Write an Analytical Essay Conclusion

Whether you write a literary analysis essay or other types of assignments, there is no need to add any new data at the end of your analysis paper. Instead, summarize the arguments you mentioned in your analytical essay outline. The conclusion of your analysis essay should be short and clear. Here, you need to demonstrate that you have achieved your goals.

Analytical Essay Writing Tips

If you want to get the highest grade for your analytical essay, you need to know a little bit more than just the basics of paper writing. Read these handy tips to write a perfect essay you will be proud of:

• Double-check your paper for spelling and grammar mistakes. In case your essay contains too many errors, neither an in-depth analysis nor the elaborate writing style will make it look any better. Situations when essays of great value in terms of research and a message they convey are poorly assessed because of the abundance of mistakes are not rare. Make sure you have enough time to proofread your paper before submission. Also, you may consider asking somebody to take a fresh look at your essay and check it for you.
• Reading your analytical essay out loud helps you discover all types of errors or weak phrases. This method might seem a bit uncomfortable, but it has proved to be very effective for many students. Note that silent reading of your paper isn’t even half as helpful as reading it aloud. 
• Another great idea to check on the rhythm and flow of your paper is to ask someone to read it for you. While listening to the text, you could perceive it from another perspective and discover even more inconsistencies and mistakes.  
• Double-check the facts you use in your analytical essay. The names of people, books, research, publications, as well as dates of historical events are too important to be misspelled. Things like these show your professionalism and the way you treat your readers.

🤔 Analytical Essay: Getting Started

The key to writing an analysis paper is to choose an argument that you will defend throughout it. For example: maybe you are writing a critical analysis paper on George Orwell’s Animal Farm The first and imperative task is to think about your thesis statement. In the case of Animal Farm , the argument could be:

In Orwell’s Animal Farm , rhetoric and language prove to be more effective ways to keep social control than physical power.

The University of North Carolina at Chapel Hill gives a great explanation of the thesis statement , how to create one, and what its function is.

But that’s not all. Once you have your thesis statement, you need to break down how you will approach your analysis essay to prove your thesis. To do this, follow these steps:

• Define the main goal(s) of your analysis . Remember that it is impossible to address each and every aspect in a single paper. Know your goal and focus on it.
• Conduct research , both online and offline, to clarify the issue contained within your thesis statement.
• Identify the main parts of the issue by looking at each part separately to see how it works.
• Try to clearly understand how each part works.
• Identify the links between the various aspects of the topic .
• By using the information you found, try to solve your main problem .

At this point, you should have a clear understanding of both the topic and your thesis statement. You should also have a clear direction for your analysis paper firmly planted in your mind and recorded in writing.

This will give you what you need to produce the paper’s outline.

An outline is the starting point for your work. A typical analytical essay features the usual essay structure. A 500-word essay should consist of a one-paragraph introduction, a three-paragraph body, and a one-paragraph conclusion. Find below a great analytical essay outline sample. Feel free to use it as an example when doing your own work!

Analysis Essay: Introduction

• Start with a startling statement or provocative question.

“All animals are equal, but some animals are more equal”. Animal Farm abounds in ironic and provocative phrases to start an analytical essay.

• Introduce the work and its author.
• Give background information that would help the reader understand your opinion.
• Formulate a thesis statement informing the reader about the purpose of the essay. Essay format does not presuppose telling everything possible on the given topic. Thus, a thesis statement tells what you are going to say, implying what you will not discuss, establishing the limits.

In Animal Farm, Orwell uses different irony types to ridicule totalitarianism to manifest its inability to make every member of society equal and happy.

Analysis Essay: Body

The analytical essay structure requires 2-3 developmental paragraphs, each dedicated to one separate idea confirming your thesis statement. The following template should be used for each of the body paragraphs.

• Start with a topic sentence that supports an aspect of your thesis.

Dramatic irony is used in Animal Farm to point out society’s ignorance.

• Continue with textual evidence (paraphrase, summary, direct quotations, specific details). Use several examples that substantiate the topic sentence.

Animals are unaware of the fact that Boxer was never sent to the hospital. He was sent to the slaughterhouse. However, the reader and writer understand that this is a lie.

• Conclude with an explanation.

By allowing the readers to learn some essential facts before the characters, dramatic irony creates suspense and shows how easy it is to persuade and manipulate the public.

Analysis Essay Conclusion

The next four points will give you a short instruction on how to conclude an analytical essay.

• Never use new information or topics here.
• Restate your thesis in a different formulation.
• Summarize the body paragraphs.
• Comment on the analyzed text from a new perspective.

📔 Choosing a Title for Your Analysis Essay

Choosing a title seems like not a significant step, but it is actually very important. The title of your critical analysis paper should:

• Entice and engage the reader
• Be unique and capture the readers’ attention
• Provide an adequate explanation of the content of the essay in just a few carefully chosen words

In the Animal Farm example, your title could be:

💁 Writing Your Analytical Essay Introduction

You must understand how to compose an introduction to an analysis paper. The University of Wollongong describes the introduction as a “map” of any writing. When writing the introduction, follow these steps:

• Provide a lead-in for the reader by offering a general introduction to the topic of the paper.
• Include your thesis statement , which shifts the reader from the generalized introduction to the specific topic and its related issues to your unique take on the essay topic.
• Present a general outline of the analysis paper.

Watch this great video for further instructions on how to write an introduction to an analysis essay.

Example of an Analytical Essay Introduction

“Four legs good, two legs bad” is one of the many postulates invented by George Orwell for his characters in Animal Farm to vest them with socialist ideology and control over the animal population. The social revolution on Manor Farm was built on language instruments, first for the collective success of the animals, and later for the power consolidation by the pigs. The novel was written in 1945 when the transition from limitless freedoms of socialist countries transformed into dictatorship. Through his animal protagonists, the author analyzes the reasons for peoples’ belief in the totalitarian regime. In Orwell’s Animal Farm , rhetoric and language prove to be more effective ways to keep social control than physical power.

🏋 Writing Your Analytical Essay Body

The body of the paper may be compared to its heart. This is the part where you show off your talent for analysis by providing convincing, well-researched, and well-thought-out arguments to support your thesis statement. You have already gathered the information, and now all you may start crafting your paper.

To make the body of an analytical essay, keep the following in mind:

• Discuss one argument per paragraph , although each argument can relate to multiple issues
• Strike a balance between writing in an unbiased tone, while expressing your personal opinion
• Be reasonable when making judgments regarding any of the problems you discuss
• Remember to include the opposing point of view to create a balanced perspective

The bottom line is: you want to offer opposing views, but you must pose your arguments so they will counter those opposing views and prove your point of view. Follow these steps when constructing each body paragraph:

• Choose the main sentence. The main or topic sentence will be the first line in your essay. The topic sentence is responsible for presenting the argument you will discuss in the paragraph and demonstrate how this argument relates to the thesis statement.
• Provide the context for the topic sentence , whether it relates to a quote, a specific incident in society, or something else. Offer evidence on who, what, where, when, why, and how.
• Give your analysis of the argument and how it adequately proves your thesis.
• Write a closing sentence that sums up the paragraph and provides a transition to the following paragraph.

Example of an Analytical Essay Body

Literacy can grant power, provided that there are animals who cannot read or write. In the beginning, the animals’ literacy and intellect are relatively the same. Old Major is the cleverest pig; he is the kind old philosopher, like Karl Marx or Vladimir Lenin. During his retirement, he develops a theory that all humans are the root of evil. His speech was the foundation for the pigs’ assumption of power. They refined his ideas into a new ideology and called it Animalism. They also learned how to read. It allowed the pigs to declare themselves the “mind workers.” Therefore, the pigs’ literacy assured the illiterate animals in their objective superiority.

Meanwhile, as the pigs were the intellectual elite, they were not supposed to work, which raised their social status by itself. Snowball tried to promote education among all the animals, but most of them failed to master the alphabet. This is a metaphor for the general public being predominantly ignorant and easy to manipulate. At the same time, Boxer and other animals that spend most of the day in hard work merely have no time to develop their intellect. Thus, the pigs’ intention to build a school for pig children was highly efficient. Unequal access to education and unequal ability to express one’s thoughts in perspective reinforce the social divide, making the pigs smarter and more powerful and undermining other animals’ self-esteem.

At this point, the pigs resort to propaganda and rhetoric. Squealer uses his oratorical gift to refine the pigs’ message to the other animals. Upon Napoleon’s order, he breaks the Seven Commandments of farm governance. At night, he climbs the ladder to change them, and once even falls from the ladder trying to change the commandment on alcohol. The “proletarian” animals soon forget what the Seven Commandments were like in the first place and are unsure if they have ever been altered. Further on, Minimus writes a poem praising Napoleon. Finally, Squealer replaces the Commandments with a single assertion: “All animals are equal, but some animals are more equal than others.” Language is no longer used to convince. It is used to control and manipulate.

🏁 Writing Your Analytical Essay Conclusion

The conclusion is short and sweet. It summarizes everything you just wrote in the essay and wraps it up with a beautiful shiny bow. Follow these steps to write a convincing conclusion:

• Repeat the thesis statement and summarize your argument. Even when using the best summary generator for the task, reread it to make sure all the crucial points are included.
• Take your argument beyond what is simply stated in your paper. You want to show how it is essential in terms of the bigger picture. Also, you may dwell on the influence on citizens of the country.

Example of an Analytical Essay Conclusion

Because of everything mentioned above, it becomes clear that language and rhetoric can rise to power, establish authority, and manipulate ordinary people. Animal Farm is the simplified version of a communist society. It shows how wise philosophers’ good intentions can be used by mean leaders to gain unopposed power and unconditional trust. Unfortunately, this can lead to the death of many innocent animals, i.e., people, as totalitarianism has nothing to do with people’s rule. Therefore, language and oratory are potent tools that can keep people oppressed and weak, deprive them of any chance for improvement and growth, and make them think that there is no other possible existence.

Now you are ready to write an analysis essay! See, it’s easier than you thought.

✏️ Analysis Essay FAQ

A great analytical paper should be well-structured, cohesive, and logically consistent. Each part of the essay should be in its place, creating a smooth and easy-to-read text. Most importantly, the statements should be objective and backed by arguments and examples.

It is a paper devoted to analyzing a certain topic or subject. An analysis essay is all about reviewing certain details of the subject and interpreting them. For example, such an analysis for a poem includes a description of artistic means that helped the poet convey the idea.

Writing an analytical essay on a book/movie/poem start with an outline. Point out what catches the eye when reviewing the subject. See how these details can be interpreted. Make sure that you refer to the main idea/message. Add an appropriate introduction and a logical conclusion.

Sat / act prep online guides and tips, 5 steps to write a great analytical essay.

General Education

Do you need to write an analytical essay for school? What sets this kind of essay apart from other types, and what must you include when you write your own analytical essay? In this guide, we break down the process of writing an analytical essay by explaining the key factors your essay needs to have, providing you with an outline to help you structure your essay, and analyzing a complete analytical essay example so you can see what a finished essay looks like.

What Is an Analytical Essay?

Before you begin writing an analytical essay, you must know what this type of essay is and what it includes. Analytical essays analyze something, often (but not always) a piece of writing or a film.

An analytical essay is more than just a synopsis of the issue though; in this type of essay you need to go beyond surface-level analysis and look at what the key arguments/points of this issue are and why. If you’re writing an analytical essay about a piece of writing, you’ll look into how the text was written and why the author chose to write it that way. Instead of summarizing, an analytical essay typically takes a narrower focus and looks at areas such as major themes in the work, how the author constructed and supported their argument, how the essay used literary devices to enhance its messages, etc.

While you certainly want people to agree with what you’ve written, unlike with persuasive and argumentative essays, your main purpose when writing an analytical essay isn’t to try to convert readers to your side of the issue. Therefore, you won’t be using strong persuasive language like you would in those essay types. Rather, your goal is to have enough analysis and examples that the strength of your argument is clear to readers.

Besides typical essay components like an introduction and conclusion, a good analytical essay will include:

• A thesis that states your main argument
• Analysis that relates back to your thesis and supports it
• Examples to support your analysis and allow a more in-depth look at the issue

In the rest of this article, we’ll explain how to include each of these in your analytical essay.

How to Structure Your Analytical Essay

Analytical essays are structured similarly to many other essays you’ve written, with an introduction (including a thesis), several body paragraphs, and a conclusion. Below is an outline you can follow when structuring your essay, and in the next section we go into more detail on how to write an analytical essay.

Introduction

Your introduction will begin with some sort of attention-grabbing sentence to get your audience interested, then you’ll give a few sentences setting up the topic so that readers have some context, and you’ll end with your thesis statement. Your introduction will include:

• Brief background information explaining the issue/text
• Your thesis

Body Paragraphs

Your analytical essay will typically have three or four body paragraphs, each covering a different point of analysis. Begin each body paragraph with a sentence that sets up the main point you’ll be discussing. Then you’ll give some analysis on that point, backing it up with evidence to support your claim. Continue analyzing and giving evidence for your analysis until you’re out of strong points for the topic. At the end of each body paragraph, you may choose to have a transition sentence that sets up what the next paragraph will be about, but this isn’t required. Body paragraphs will include:

• Introductory sentence explaining what you’ll cover in the paragraph (sort of like a mini-thesis)
• Analysis point
• Evidence (either passages from the text or data/facts) that supports the analysis
• (Repeat analysis and evidence until you run out of examples)

You won’t be making any new points in your conclusion; at this point you’re just reiterating key points you’ve already made and wrapping things up. Begin by rephrasing your thesis and summarizing the main points you made in the essay. Someone who reads just your conclusion should be able to come away with a basic idea of what your essay was about and how it was structured. After this, you may choose to make some final concluding thoughts, potentially by connecting your essay topic to larger issues to show why it’s important. A conclusion will include:

• Paraphrase of thesis
• Summary of key points of analysis
• Final concluding thought(s)

5 Steps for Writing an Analytical Essay

Follow these five tips to break down writing an analytical essay into manageable steps. By the end, you’ll have a fully-crafted analytical essay with both in-depth analysis and enough evidence to support your argument. All of these steps use the completed analytical essay in the next section as an example.

#1: Pick a Topic

You may have already had a topic assigned to you, and if that’s the case, you can skip this step. However, if you haven’t, or if the topic you’ve been assigned is broad enough that you still need to narrow it down, then you’ll need to decide on a topic for yourself. Choosing the right topic can mean the difference between an analytical essay that’s easy to research (and gets you a good grade) and one that takes hours just to find a few decent points to analyze

Before you decide on an analytical essay topic, do a bit of research to make sure you have enough examples to support your analysis. If you choose a topic that’s too narrow, you’ll struggle to find enough to write about.

For example, say your teacher assigns you to write an analytical essay about the theme in John Steinbeck’s The Grapes of Wrath of exposing injustices against migrants. For it to be an analytical essay, you can’t just recount the injustices characters in the book faced; that’s only a summary and doesn’t include analysis. You need to choose a topic that allows you to analyze the theme. One of the best ways to explore a theme is to analyze how the author made his/her argument. One example here is that Steinbeck used literary devices in the intercalary chapters (short chapters that didn’t relate to the plot or contain the main characters of the book) to show what life was like for migrants as a whole during the Dust Bowl.

You could write about how Steinbeck used literary devices throughout the whole book, but, in the essay below, I chose to just focus on the intercalary chapters since they gave me enough examples. Having a narrower focus will nearly always result in a tighter and more convincing essay (and can make compiling examples less overwhelming).

#2: Write a Thesis Statement

Your thesis statement is the most important sentence of your essay; a reader should be able to read just your thesis and understand what the entire essay is about and what you’ll be analyzing. When you begin writing, remember that each sentence in your analytical essay should relate back to your thesis

In the analytical essay example below, the thesis is the final sentence of the first paragraph (the traditional spot for it). The thesis is: “In The Grapes of Wrath’s intercalary chapters, John Steinbeck employs a variety of literary devices and stylistic choices to better expose the injustices committed against migrants in the 1930s.” So what will this essay analyze? How Steinbeck used literary devices in the intercalary chapters to show how rough migrants could have it. Crystal clear.

#3: Do Research to Find Your Main Points

This is where you determine the bulk of your analysis--the information that makes your essay an analytical essay. My preferred method is to list every idea that I can think of, then research each of those and use the three or four strongest ones for your essay. Weaker points may be those that don’t relate back to the thesis, that you don’t have much analysis to discuss, or that you can’t find good examples for. A good rule of thumb is to have one body paragraph per main point

This essay has four main points, each of which analyzes a different literary device Steinbeck uses to better illustrate how difficult life was for migrants during the Dust Bowl. The four literary devices and their impact on the book are:

• Lack of individual names in intercalary chapters to illustrate the scope of the problem
• Parallels to the Bible to induce sympathy for the migrants
• Non-showy, often grammatically-incorrect language so the migrants are more realistic and relatable to readers
• Nature-related metaphors to affect the mood of the writing and reflect the plight of the migrants

#4: Find Excerpts or Evidence to Support Your Analysis

Now that you have your main points, you need to back them up. If you’re writing a paper about a text or film, use passages/clips from it as your main source of evidence. If you’re writing about something else, your evidence can come from a variety of sources, such as surveys, experiments, quotes from knowledgeable sources etc. Any evidence that would work for a regular research paper works here.

In this example, I quoted multiple passages from The Grapes of Wrath  in each paragraph to support my argument. You should be able to back up every claim you make with evidence in order to have a strong essay.

#5: Put It All Together

Now it's time to begin writing your essay, if you haven’t already. Create an introductory paragraph that ends with the thesis, make a body paragraph for each of your main points, including both analysis and evidence to back up your claims, and wrap it all up with a conclusion that recaps your thesis and main points and potentially explains the big picture importance of the topic.

Analytical Essay Example + Analysis

So that you can see for yourself what a completed analytical essay looks like, here’s an essay I wrote back in my high school days. It’s followed by analysis of how I structured my essay, what its strengths are, and how it could be improved.

One way Steinbeck illustrates the connections all migrant people possessed and the struggles they faced is by refraining from using specific titles and names in his intercalary chapters. While The Grapes of Wrath focuses on the Joad family, the intercalary chapters show that all migrants share the same struggles and triumphs as the Joads. No individual names are used in these chapters; instead the people are referred to as part of a group. Steinbeck writes, “Frantic men pounded on the doors of the doctors; and the doctors were busy.  And sad men left word at country stores for the coroner to send a car,” (555). By using generic terms, Steinbeck shows how the migrants are all linked because they have gone through the same experiences. The grievances committed against one family were committed against thousands of other families; the abuse extends far beyond what the Joads experienced. The Grapes of Wrath frequently refers to the importance of coming together; how, when people connect with others their power and influence multiplies immensely. Throughout the novel, the goal of the migrants, the key to their triumph, has been to unite. While their plans are repeatedly frustrated by the government and police, Steinbeck’s intercalary chapters provide a way for the migrants to relate to one another because they have encountered the same experiences. Hundreds of thousands of migrants fled to the promised land of California, but Steinbeck was aware that numbers alone were impersonal and lacked the passion he desired to spread. Steinbeck created the intercalary chapters to show the massive numbers of people suffering, and he created the Joad family to evoke compassion from readers.  Because readers come to sympathize with the Joads, they become more sensitive to the struggles of migrants in general. However, John Steinbeck frequently made clear that the Joads were not an isolated incident; they were not unique. Their struggles and triumphs were part of something greater. Refraining from specific names in his intercalary chapters allows Steinbeck to show the vastness of the atrocities committed against migrants.

Steinbeck also creates significant parallels to the Bible in his intercalary chapters in order to enhance his writing and characters. By using simple sentences and stylized writing, Steinbeck evokes Biblical passages. The migrants despair, “No work till spring. No work,” (556).  Short, direct sentences help to better convey the desperateness of the migrants’ situation. Throughout his novel, John Steinbeck makes connections to the Bible through his characters and storyline. Jim Casy’s allusions to Christ and the cycle of drought and flooding are clear biblical references.  By choosing to relate The Grapes of Wrath to the Bible, Steinbeck’s characters become greater than themselves. Starving migrants become more than destitute vagrants; they are now the chosen people escaping to the promised land. When a forgotten man dies alone and unnoticed, it becomes a tragedy. Steinbeck writes, “If [the migrants] were shot at, they did not run, but splashed sullenly away; and if they were hit, they sank tiredly in the mud,” (556). Injustices committed against the migrants become greater because they are seen as children of God through Steinbeck’s choice of language. Referencing the Bible strengthens Steinbeck’s novel and purpose: to create understanding for the dispossessed.  It is easy for people to feel disdain for shabby vagabonds, but connecting them to such a fundamental aspect of Christianity induces sympathy from readers who might have otherwise disregarded the migrants as so many other people did.

The simple, uneducated dialogue Steinbeck employs also helps to create a more honest and meaningful representation of the migrants, and it makes the migrants more relatable to readers. Steinbeck chooses to accurately represent the language of the migrants in order to more clearly illustrate their lives and make them seem more like real paper than just characters in a book. The migrants lament, “They ain’t gonna be no kinda work for three months,” (555). There are multiple grammatical errors in that single sentence, but it vividly conveys the despair the migrants felt better than a technically perfect sentence would. The Grapes of Wrath is intended to show the severe difficulties facing the migrants so Steinbeck employs a clear, pragmatic style of writing.  Steinbeck shows the harsh, truthful realities of the migrants’ lives and he would be hypocritical if he chose to give the migrants a more refined voice and not portray them with all their shortcomings. The depiction of the migrants as imperfect through their language also makes them easier to relate to. Steinbeck’s primary audience was the middle class, the less affluent of society. Repeatedly in The Grapes of Wrath , the wealthy make it obvious that they scorn the plight of the migrants. The wealthy, not bad luck or natural disasters, were the prominent cause of the suffering of migrant families such as the Joads. Thus, Steinbeck turns to the less prosperous for support in his novel. When referring to the superior living conditions barnyard animals have, the migrants remark, “Them’s horses-we’re men,” (556).  The perfect simplicity of this quote expresses the absurdness of the migrants’ situation better than any flowery expression could.

In The Grapes of Wrath , John Steinbeck uses metaphors, particularly about nature, in order to illustrate the mood and the overall plight of migrants. Throughout most of the book, the land is described as dusty, barren, and dead. Towards the end, however; floods come and the landscape begins to change. At the end of chapter twenty-nine, Steinbeck describes a hill after the floods saying, “Tiny points of grass came through the earth, and in a few days the hills were pale green with the beginning year,” (556). This description offers a stark contrast from the earlier passages which were filled with despair and destruction. Steinbeck’s tone from the beginning of the chapter changes drastically. Early in the chapter, Steinbeck had used heavy imagery in order to convey the destruction caused by the rain, “The streams and the little rivers edged up to the bank sides and worked at willows and tree roots, bent the willows deep in the current, cut out the roots of cottonwoods and brought down the trees,” (553). However, at the end of the chapter the rain has caused new life to grow in California. The new grass becomes a metaphor representing hope. When the migrants are at a loss over how they will survive the winter, the grass offers reassurance. The story of the migrants in the intercalary chapters parallels that of the Joads. At the end of the novel, the family is breaking apart and has been forced to flee their home. However, both the book and final intercalary chapter end on a hopeful note after so much suffering has occurred. The grass metaphor strengthens Steinbeck’s message because it offers a tangible example of hope. Through his language Steinbeck’s themes become apparent at the end of the novel. Steinbeck affirms that persistence, even when problems appear insurmountable, leads to success. These metaphors help to strengthen Steinbeck’s themes in The Grapes of Wrath because they provide a more memorable way to recall important messages.

John Steinbeck’s language choices help to intensify his writing in his intercalary chapters and allow him to more clearly show how difficult life for migrants could be. Refraining from using specific names and terms allows Steinbeck to show that many thousands of migrants suffered through the same wrongs. Imitating the style of the Bible strengthens Steinbeck’s characters and connects them to the Bible, perhaps the most famous book in history. When Steinbeck writes in the imperfect dialogue of the migrants, he creates a more accurate portrayal and makes the migrants easier to relate to for a less affluent audience. Metaphors, particularly relating to nature, strengthen the themes in The Grapes of Wrath by enhancing the mood Steinbeck wants readers to feel at different points in the book. Overall, the intercalary chapters that Steinbeck includes improve his novel by making it more memorable and reinforcing the themes Steinbeck embraces throughout the novel. Exemplary stylistic devices further persuade readers of John Steinbeck’s personal beliefs. Steinbeck wrote The Grapes of Wrath to bring to light cruelties against migrants, and by using literary devices effectively, he continuously reminds readers of his purpose. Steinbeck’s impressive language choices in his intercalary chapters advance the entire novel and help to create a classic work of literature that people still are able to relate to today. 

This essay sticks pretty closely to the standard analytical essay outline. It starts with an introduction, where I chose to use a quote to start off the essay. (This became my favorite way to start essays in high school because, if I wasn’t sure what to say, I could outsource the work and find a quote that related to what I’d be writing about.) The quote in this essay doesn’t relate to the themes I’m discussing quite as much as it could, but it’s still a slightly different way to start an essay and can intrigue readers. I then give a bit of background on The Grapes of Wrath and its themes before ending the intro paragraph with my thesis: that Steinbeck used literary devices in intercalary chapters to show how rough migrants had it.

Each of my four body paragraphs is formatted in roughly the same way: an intro sentence that explains what I’ll be discussing, analysis of that main point, and at least two quotes from the book as evidence.

My conclusion restates my thesis, summarizes each of four points I discussed in my body paragraphs, and ends the essay by briefly discussing how Steinbeck’s writing helped introduce a world of readers to the injustices migrants experienced during the dust bowl.

What does this analytical essay example do well? For starters, it contains everything that a strong analytical essay should, and it makes that easy to find. The thesis clearly lays out what the essay will be about, the first sentence of each of the body paragraph introduces the topic it’ll cover, and the conclusion neatly recaps all the main points. Within each of the body paragraphs, there’s analysis along with multiple excerpts from the book in order to add legitimacy to my points.

Additionally, the essay does a good job of taking an in-depth look at the issue introduced in the thesis. Four ways Steinbeck used literary devices are discussed, and for each of the examples are given and analysis is provided so readers can understand why Steinbeck included those devices and how they helped shaped how readers viewed migrants and their plight.

Where could this essay be improved? I believe the weakest body paragraph is the third one, the one that discusses how Steinbeck used plain, grammatically incorrect language to both accurately depict the migrants and make them more relatable to readers. The paragraph tries to touch on both of those reasons and ends up being somewhat unfocused as a result. It would have been better for it to focus on just one of those reasons (likely how it made the migrants more relatable) in order to be clearer and more effective. It’s a good example of how adding more ideas to an essay often doesn’t make it better if they don’t work with the rest of what you’re writing. This essay also could explain the excerpts that are included more and how they relate to the points being made. Sometimes they’re just dropped in the essay with the expectation that the readers will make the connection between the example and the analysis. This is perhaps especially true in the second body paragraph, the one that discusses similarities to Biblical passages. Additional analysis of the quotes would have strengthened it.

Summary: How to Write an Analytical Essay

What is an analytical essay? A critical analytical essay analyzes a topic, often a text or film. The analysis paper uses evidence to support the argument, such as excerpts from the piece of writing. All analytical papers include a thesis, analysis of the topic, and evidence to support that analysis.

How To Write An Analytical Essay A Full Guide

Crafting an impeccable analytical essay is an art form that demands precision, insight, and a structured approach. Whether you’re delving into literature, dissecting historical events, or unraveling scientific theories, the ability to present a compelling analysis is pivotal. Here’s a comprehensive guide to navigate the intricate path of writing a flawless analytical essay.

What Is An Analytical Essay

An analytical essay is a type of academic writing that delves deeply into a topic, idea, or piece of literature. Unlike descriptive or narrative essays, which focus on providing a vivid description or telling a story, an analytical essay aims to examine and dissect its subject matter.

The primary objective of an analytical essay is to present a thorough analysis or interpretation of the subject, often breaking it down into its constituent parts and scrutinizing how they contribute to the whole.

Why Analytical Essay Is Important

Analytical essays play a pivotal role in developing critical thinking skills and fostering a deeper understanding of complex subjects. Through the meticulous examination and interpretation of information, these essays teach individuals how to dissect arguments, evaluate evidence, and form well-supported conclusions. They serve as a platform for honing analytical prowess, enabling individuals to engage with diverse perspectives, challenge assumptions, and articulate their insights effectively. Moreover, mastering the art of analytical essays equips individuals with invaluable skills applicable across various disciplines, fostering a capacity for logical reasoning, problem-solving, and persuasive communication—a skill set indispensable in academia, professional endeavors, and everyday life.

Tips For Writing A Good Analytical Essay

Understanding the essence.

To excel in analytical writing, one must comprehend the essence of analysis itself. It’s not merely about summarizing or narrating; it’s about deconstructing the core components, scrutinizing their significance, and synthesizing perspectives to derive insightful conclusions.

Devising a Strategic Blueprint

Begin with a comprehensive understanding of your subject matter. Formulate a thesis statement —a succinct encapsulation of your perspective—which serves as the guiding beacon throughout your essay. Craft an outline delineating key sections and their respective arguments, ensuring a logical flow that seamlessly connects each point.

The Pinnacle of Research

A sturdy analytical essay is built upon a foundation of rigorous research. Delve into reputable sources, be it scholarly articles, books, or credible online repositories. Gather diverse perspectives and data to fortify your arguments, but always uphold the standards of credibility and relevance.

Structure: The Backbone of Brilliance

A well-structured essay is akin to an architectural marvel. The introduction should entice readers with a gripping hook, provide context, and introduce the thesis statement. The body paragraphs, each beginning with a topic sentence, should expound on individual arguments supported by evidence and analysis. Finally, the conclusion should reaffirm the thesis while offering a nuanced synthesis of the essay’s core ideas.

The Art of Analysis

Here’s where the magic unfolds. Analyze, dissect, and interpret the data and evidence gathered. Scrutinize underlying themes, dissect intricate details, and juxtapose contrasting viewpoints. Employ analytical tools pertinent to your subject, such as literary devices for literature analyses, statistical methods for scientific inquiries, or historical frameworks for historical essays.

Precision in Language and Style

The language employed in an analytical essay should be precise, articulate, and tailored to convey complex ideas clearly. Utilize a formal tone, vary sentence structures, and employ transitions to ensure a seamless progression of ideas. Embrace clarity and coherence as your allies in elucidating intricate analyses.

Revisiting and Refining

Revision is the crucible wherein a good essay transforms into a great one. Review your work meticulously—check for coherence, refine arguments, ensure logical transitions, and verify the alignment of evidence with your thesis. Seek feedback from peers or mentors to gain diverse perspectives and refine your essay further.

Conclusion: A Culmination of Mastery

In conclusion, a perfect analytical essay isn’t merely a collection of facts and opinions; it’s an orchestrated symphony of critical thinking, analysis, and eloquent expression. Embrace the journey of discovery, relish the complexities, and let your essay resonate as a testament to your mastery of analytical prowess.

Organizing Your Analysis

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

This resource covers how to write a rhetorical analysis essay of primarily visual texts with a focus on demonstrating the author’s understanding of the rhetorical situation and design principles.

There is no one perfect way to organize a rhetorical analysis essay. In fact, writers should always be a bit leery of plug-in formulas that offer a perfect essay format. Remember, organization itself is not the enemy, only organization without considering the specific demands of your particular writing task. That said, here are some general tips for plotting out the overall form of your essay.

Introduction

Like any rhetorical analysis essay, an essay analyzing a visual document should quickly set the stage for what you’re doing. Try to cover the following concerns in the initial paragraphs:

• Make sure to let the reader know you’re performing a rhetorical analysis. Otherwise, they may expect you to take positions or make an evaluative argument that may not be coming.
• Clearly state what the document under consideration is and possibly give some pertinent background information about its history or development. The intro can be a good place for a quick, narrative summary of the document. The key word here is “quick, for you may be dealing with something large (for example, an entire episode of a cartoon like the Simpsons). Save more in-depth descriptions for your body paragraph analysis.
• If you’re dealing with a smaller document (like a photograph or an advertisement), and copyright allows, the introduction or first page is a good place to integrate it into your page.
• Give a basic run down of the rhetorical situation surrounding the document: the author, the audience, the purpose, the context, etc.

Thesis Statements and Focus

Many authors struggle with thesis statements or controlling ideas in regards to rhetorical analysis essays. There may be a temptation to think that merely announcing the text as a rhetorical analysis is purpose enough. However, especially depending on your essay’s length, your reader may need a more direct and clear statement of your intentions. Below are a few examples.

1. Clearly narrow the focus of what your essay will cover. Ask yourself if one or two design aspects of the document is interesting and complex enough to warrant a full analytical treatment.

The website for Amazon.com provides an excellent example of alignment and proximity to assist its visitors in navigating a potentially large and confusing amount of information.

2. Since visual documents often seek to move people towards a certain action (buying a product, attending an event, expressing a sentiment), an essay may analyze the rhetorical techniques used to accomplish this purpose. The thesis statement should reflect this goal.

The call-out flyer for the Purdue Rowing Team uses a mixture of dynamic imagery and tantalizing promises to create interest in potential, new members.

3. Rhetorical analysis can also easily lead to making original arguments. Performing the analysis may lead you to an argument; or vice versa, you may start with an argument and search for proof that supports it.

A close analysis of the female body images in the July 2007 issue of Cosmopolitan magazine reveals contradictions between the articles’ calls for self-esteem and the advertisements’ unrealistic, beauty demands.

These are merely suggestions. The best measure for what your focus and thesis statement should be the document itself and the demands of your writing situation. Remember that the main thrust of your thesis statement should be on how the document creates meaning and accomplishes its purposes. The OWl has additional information on writing thesis statements.

Analysis Order (Body Paragraphs)

Depending on the genre and size of the document under analysis, there are a number of logical ways to organize your body paragraphs. Below are a few possible options. Which ever you choose, the goal of your body paragraphs is to present parts of the document, give an extended analysis of how that part functions, and suggest how the part ties into a larger point (your thesis statement or goal).

Chronological

This is the most straight-forward approach, but it can also be effective if done for a reason (as opposed to not being able to think of another way). For example, if you are analyzing a photo essay on the web or in a booklet, a chronological treatment allows you to present your insights in the same order that a viewer of the document experiences those images. It is likely that the images have been put in that order and juxtaposed for a reason, so this line of analysis can be easily integrated into the essay.

Be careful using chronological ordering when dealing with a document that contains a narrative (i.e. a television show or music video). Focusing on the chronological could easily lead you to plot summary which is not the point of a rhetorical analysis.

A spatial ordering covers the parts of a document in the order the eye is likely to scan them. This is different than chronological order, for that is dictated by pages or screens where spatial order concerns order amongst a single page or plane. There are no unwavering guidelines for this, but you can use the following general guidelines.

• Left to right and top to down is still the normal reading and scanning pattern for English-speaking countries.
• The eye will naturally look for centers. This may be the technical center of the page or the center of the largest item on the page.
• Lines are often used to provide directions and paths for the eye to follow.
• Research has shown that on web pages, the eye tends to linger in the top left quadrant before moving left to right. Only after spending a considerable amount of time on the top, visible portion of the page will they then scroll down.

Persuasive Appeals

The classic, rhetorical appeals are logos, pathos, and ethos. These concepts roughly correspond to the logic, emotion, and character of the document’s attempt to persuade. You can find more information on these concepts elsewhere on the OWL. Once you understand these devices, you could potentially order your essay by analyzing the document’s use of logos, ethos, and pathos in different sections.

The conclusion of a rhetorical analysis essay may not operate too differently from the conclusion of any other kind of essay. Still, many writers struggle with what a conclusion should or should not do. You can find tips elsewhere on the OWL on writing conclusions. In short, however, you should restate your main ideas and explain why they are important; restate your thesis; and outline further research or work you believe should be completed to further your efforts.

 How to Write a Perfect Analytical Paragraph

• 8-minute read
• 30th January 2023

If you are looking up how to write an analytical paragraph, you are most likely writing an argumentative or analytical essay. Analytical essays are similar to other essays, such as descriptive essays, in that you have a central idea, organize supporting ideas into body paragraphs, and make conclusions.

However, analytical essays differ from other essays because the writer must go further. They require the writer to interpret and analyze a given text or information using evidence to support their central idea or thesis statement. This analysis takes place in analytical paragraphs, or body paragraphs, if you are writing an analytical essay .

In this article, you’ll learn the components of a perfect analytical paragraph: the topic sentence, evidence, analysis, and conclusion. Keep reading to learn more.

What Is an Analytical Paragraph?

An analytical paragraph is a paragraph that breaks down a piece of literature, an idea, or a concept into smaller parts and analyzes each part to understand the whole. Being able to write an effective and successful analytical paragraph reflects a writer’s critical thinking and organizational writing skills. All in all, like any other type of writing, writing an analytical paragraph requires skill and practice.

Write the Topic Sentence

A topic sentence is usually the first, or sometimes second, sentence at the beginning of anybody paragraph. Your topic sentence should contain one main idea related to the thesis statement . If it is not related to your thesis statement, then you are likely off topic.

Pro Tip: If your topic sentence is the second sentence of your paragraph, then your first sentence should be a transitional sentence .

Let’s look at a thesis statement and some topic sentences to get a better idea.

Topic: Examine and analyze the marriages in George Eliot’s Middlemarch .

Thesis Statement: Eliot uses three different marriages to give depth to everyday people and show the reader the struggles of marriage within the nineteenth century’s societal standards of submissive roles, class range, and financial status.

Topic Sentence 1: Lydgate and Rosamond had a terrible marriage in Middlemarch , like all other marriages during this time.

This topic sentence is not effective because it is not specific enough and does not directly relate to the thesis statement. It does not mention how their “terrible” marriage is related to submissive roles, class range, or financial status. Additionally, the overly generalized language of “all” marriages being terrible marriages during this time is a weak argument.

Topic Sentence 2: Financial matters play a huge role in the Lydgate and Rosamond marriage, as Lydgate has no money and Rosamond is a big spender.

This topic sentence is effective because it directly supports the thesis statement. It is focused on the financial status of this marriage.

Provide Evidence

The type of evidence you use to support your topic sentence will largely depend on the topic of your analytical essay. For example, if you are writing an essay related to a work of literature, you will need to provide direct quotes, paraphrasing, specific details, or a summary from the work to support your main idea. If your topic is related to analyzing data, then you may use figures, statistics, or charts and graph evidence to support your topic sentence.

Regardless of what type of evidence you provide, it must be appropriate and directly relate to and support your topic sentence.

For example, if we take the above thesis and topic sentence, we might select direct quotes, paraphrases, or summaries from the novel Middlemarch that depict the marriage’s financial stress.

Pro Tip: When using direct quotes, make sure you always provide an in-text citation and use correct punctuation to ensure your essay is neat and clean.

Once you have provided evidence, you should analyze it to illustrate its significance and how it relates to the topic sentence. In your analysis, you can discuss how an author uses certain literary devices to emphasize character traits, themes, patterns, and connections in a literary work.

Be sure that your analysis always connects to the topic sentence/main idea of the paragraph. Avoid introducing new ideas in this section. Save those for later paragraphs or consider creating a new one to explore and analyze the new point.

Conclude Your Paragraph

When closing an analytical paragraph, you can consider doing two things:

●  Briefly emphasize the main point your reader should take away after having read the paragraph.

●  Begin a transition if the analysis continues into the next paragraph. (This strategy may be more suitable for longer, more in-depth analytical essays).

Using the above example topic sentence, we might conclude the paragraph as follows:

Notice how this concluding statement not only emphasizes the main points from the paragraph but also ties back into the thesis statement.

Writing Tips For Analytical Paragraphs

Leave out first person language.

Avoid using language such as “in my opinion,” “from my perspective,” or “I think.” While the analysis is your interpretation of a text or information, you should rely on and focus on using evidence to support your ideas. Overall, you should aim to maintain an objective tone .

Instead of saying “I think Rosamond is manipulative,” you should use evidence from the text to show that she was manipulative. For example, “Rosamond shows a pattern of manipulation throughout Middlemarch , specifically toward her husband. For instance, she says, ‘…’”

Do Writing Exercises

When writing, especially in the early drafts of an essay, it is typical to find the main idea of a paragraph at the end. This is a natural course for our thinking process. However, the main idea should be presented as your topic sentence at the beginning of this paragraph. Additionally, most students leave this main idea at the end because they do not identify it as the main idea.

To overcome this dilemma, try a looping prewriting exercise . In this exercise, you write continuously for a designated time (maybe 10 minutes, your choice). At the end of that time, read over what you’ve written and circle the main idea of the text (this is usually at the end). In the next cycle, you start with this main idea at the beginning and further examine and analyze it.

This is a wonderful exercise to help you pick out main ideas and delve deeper into your analysis.

Get Feedback

If you are a student, there are several options to get feedback for free. Ask a friend to read your essay. Go to your writing center to get feedback and help with your writing. Go to your professor’s office hours with your writing or questions to get detailed advice. More often than not, they are happy to see you take advantage of their expertise.

As a working professional, writer, or author, you can look to fellow authors or bookish friends to read your work. You can find free beta readers online from sites such as Goodreads to get feedback from your target audience. You can also find writing groups on social media platforms.

Proofread Your Work

It can be easy to finish writing an essay and think “Finally, I’m done!” Unfortunately, that is only half the process. Be sure to always read and reread your writing before hitting submit. Check for stray commas, spelling errors, or awkward sentences to make your main ideas and hard work shine. Learn about 6 Quick and Easy Tips for Proofreading you can do at home.

Writing an analytical paragraph doesn’t have to be stressful. Be sure to include a topic sentence at the beginning of your paragraph that connects to the thesis statement. Provide a variety of evidence to support your main idea, analyze the text by highlighting literary devices used, themes, and patterns, and end with a brief concluding statement.

What Is a Topic Sentence?

A topic sentence goes at the beginning of a body paragraph and clearly states the main idea of the paragraph.

How Do I Organize an Analytical Paragraph?

An analytical paragraph has four components: topic sentence, evidence, analysis, and conclusion. The topic sentence is the most important part of any body paragraph because it establishes the main idea of the paragraph and relates to the thesis statement.

What Makes a Good Analytical Paragraph?

A good analytical paragraph has a clear topic sentence, strong evidence, and a thorough analysis that reflects the writer’s critical thinking and writing skills. It should conclude by emphasizing the main idea of the paragraph and how it supports the essay overall.

How to Write an Analysis

Last Updated: March 28, 2024 Fact Checked

This article was co-authored by Christopher Taylor, PhD and by wikiHow staff writer, Megaera Lorenz, PhD . Christopher Taylor is an Adjunct Assistant Professor of English at Austin Community College in Texas. He received his PhD in English Literature and Medieval Studies from the University of Texas at Austin in 2014. There are 14 references cited in this article, which can be found at the bottom of the page.

An analysis is a piece of writing that looks at some aspect of a document in detail. To write a good analysis, you’ll need to ask yourself questions that focus on how and why the document works the way it does. You can start the process by gathering information about the subject of your analysis and defining the questions your analysis will answer. Once you’ve outlined your main arguments, look for specific evidence to support them. You can then work on putting your analysis together into a coherent piece of writing.

Gathering Information and Building Your Argument

• If your analysis is supposed to answer a specific question or focus on a particular aspect of the document you are analyzing.
• If there are any length or formatting requirements for the analysis.
• The citation style your instructor wants you to use.
• On what criteria your instructor will evaluate your analysis (e.g., organization, originality, good use of references and quotations, or correct spelling and grammar).

• The title of the document (if it has one).
• The name of the creator of the document. For example, depending on the type of document you’re working with, this could be the author, artist, director, performer, or photographer.
• The form and medium of the document (e.g., “Painting, oil on canvas”).
• When and where the document was created.
• The historical and cultural context of the work.

• Who you believe the intended audience is for the advertisement.
• What rhetorical choices the author made to persuade the audience of their main point.
• What product is being advertised.
• How the poster uses images to make the product look appealing.
• Whether there is any text in the poster, and, if so, how it works together with the images to reinforce the message of the ad.
• What the purpose of the ad is or what its main point is.

• For example, if you’re analyzing an advertisement poster, you might focus on the question: “How does this poster use colors to symbolize the problem that the product is intended to fix? Does it also use color to represent the beneficial results of using the product?”

• For example, you might write, “This poster uses the color red to symbolize the pain of a headache. The blue elements in the design represent the relief brought by the product.”
• You could develop the argument further by saying, “The colors used in the text reinforce the use of colors in the graphic elements of the poster, helping the viewer make a direct connection between the words and images.”

• For example, if you’re arguing that the advertisement poster uses red to represent pain, you might point out that the figure of the headache sufferer is red, while everyone around them is blue. Another piece of evidence might be the use of red lettering for the words “HEADACHE” and “PAIN” in the text of the poster.
• You could also draw on outside evidence to support your claims. For example, you might point out that in the country where the advertisement was produced, the color red is often symbolically associated with warnings or danger.

Tip: If you’re analyzing a text, make sure to properly cite any quotations that you use to support your arguments. Put any direct quotations in quotation marks (“”) and be sure to give location information, such as the page number where the quote appears. Additionally, follow the citation requirements for the style guide assigned by your instructor or one that's commonly used for the subject matter you're writing about.

Organizing and Drafting Your Analysis

• For example, “The poster ‘Say! What a relief,’ created in 1932 by designer Dorothy Plotzky, uses contrasting colors to symbolize the pain of a headache and the relief brought by Miss Burnham’s Pep-Em-Up Pills. The red elements denote pain, while blue ones indicate soothing relief.”

Tip: Your instructor might have specific directions about which information to include in your thesis statement (e.g., the title, author, and date of the document you are analyzing). If you’re not sure how to format your thesis statement or topic sentence, don’t hesitate to ask.

• a. Background
• ii. Analysis/Explanation
• iii. Example
• iv. Analysis/Explanation
• III. Conclusion

• For example, “In the late 1920s, Kansas City schoolteacher Ethel Burnham developed a patent headache medication that quickly achieved commercial success throughout the American Midwest. The popularity of the medicine was largely due to a series of simple but eye-catching advertising posters that were created over the next decade. The poster ‘Say! What a relief,’ created in 1932 by designer Dorothy Plotzky, uses contrasting colors to symbolize the pain of a headache and the relief brought by Miss Burnham’s Pep-Em-Up Pills.”

• Make sure to include clear transitions between each argument and each paragraph. Use transitional words and phrases, such as “Furthermore,” “Additionally,” “For example,” “Likewise,” or “In contrast . . .”
• The best way to organize your arguments will vary based on the individual topic and the specific points you are trying to make. For example, in your analysis of the poster, you might start with arguments about the red visual elements and then move on to a discussion about how the red text fits in.

• For example, you might end your essay with a few sentences about how other advertisements at the time might have been influenced by Dorothy Plotzky’s use of colors.

• For example, in your discussion of the advertisement, avoid stating that you think the art is “beautiful” or that the advertisement is “boring.” Instead, focus on what the poster was supposed to accomplish and how the designer attempted to achieve those goals.

Polishing Your Analysis

• For example, if your essay currently skips around between discussions of the red and blue elements of the poster, consider reorganizing it so that you discuss all the red elements first, then focus on the blue ones.

• For example, you might look for places where you could provide additional examples to support one of your major arguments.

• For example, if you included a paragraph about Dorothy Plotzky’s previous work as a children’s book illustrator, you may want to cut it if it doesn’t somehow relate to her use of color in advertising.
• Cutting material out of your analysis may be difficult, especially if you put a lot of thought into each sentence or found the additional material really interesting. Your analysis will be stronger if you keep it concise and to the point, however.

• You may find it helpful to have someone else go over your essay and look for any mistakes you might have missed.

Tip: When you’re reading silently, it’s easy to miss typos and other small errors because your brain corrects them automatically. Reading your work out loud can make problems easier to spot.

So, if you are ready to dive into the world of analytical essays, this comprehensive guide will provide you with the necessary tools to understand what they are, how to write them, and how to analyze actual data within your chosen topic. With this guide, you will be well-equipped to write analytical essays that not only meet academic standards but also demonstrate your critical thinking and analytical abilities.

What Is an Analytical Essay

When writing an analytical essay, it is important to connect your analysis with actual research and examples. This helps to support your arguments and make your essay more convincing. Analytical essays can be written on various topics, such as literature, history, social sciences, or even scientific research.

If you need assistance in writing your analytical essay, there are various resources available to help you. Websites like Purdue OWL and YourDictionary offer guides and examples of how to write analytical essays, as well as tips on how to structure your essay and restructure your paragraphs. Academic writers can also provide further assistance in analyzing and evaluating your essay topic.

Overall, analytical essays involve analyzing and evaluating a specific topic or idea in depth. They go beyond basic description and require critical thinking skills. By understanding the structure and patterns of analytical essays, and with the help of research and examples, you can successfully write a well-organized and convincing analytical essay.

General Structure and Format of an Analytical Essay

The body paragraphs make up the major part of your essay, where you will analyze and evaluate the data or texts you are discussing. Each paragraph should contain a topic sentence that connects to your thesis statement and provides evidence or examples to support your analysis. Remember to use critical thinking and cite any sources you reference.

To help you in structuring and formatting your analytical essay, you can use an outline. An outline helps writers organize their thoughts and ensure a logical flow of ideas. It can also help you restructure your essay if needed, as you can easily move paragraphs or sections around to improve the overall structure.

When it comes to the format of your analytical essay, it is important to follow the guidelines provided by your academic institution or instructor. Most analytical essays are written in a formal tone and use the APA or MLA citation styles. Websites such as Purdue OWL and YourDictionary provide detailed guidelines on how to format your paper and cite sources correctly.

Remember, when analyzing and writing an analytical essay, writers need to understand the difference between summary and analysis. It involves critically evaluating the data or texts within the context of your thesis statement.

Analytical Essay Body Paragraph Example

Paragraph 1:

• Thesis statement: State your thesis, which is your overall evaluation or analysis of the text. This should be a clear and concise statement that connects to the main topics of your essay.
• Main points: In this paragraph, focus on one main point that supports your thesis statement. Provide specific examples, evidence, or data from the text to support your claim.
• Analysis: Analyze the examples you provided in the previous point. Explain how they connect to your thesis and what they reveal about the text or its author.

Paragraph 2 (and beyond):

• Main points: Focus on a new main point that supports your thesis statement. Again, provide specific examples, evidence, or data from the text.
• Analysis: Analyze the new examples and discuss how they contribute to your overall analysis. Evaluate their significance and relevance to your thesis statement.

Remember that the body paragraphs of an analytical essay should focus on analyzing specific examples and providing evidence to support your claims. The structure and format of these paragraphs may vary depending on the specific requirements of your essay or the academic discipline you are writing for. However, the general pattern of introducing a main point, providing evidence and analysis, and concluding the paragraph should be followed to ensure a clear and logical argument.

Critical Analysis Paper

What is a critical analysis paper.

A critical analysis paper is an academic essay that examines a literary work or any other piece of written text with a focus on critically evaluating its structure, patterns, and themes. Unlike an analytical essay, which is more general and can be written on a variety of topics, a critical analysis paper requires writers to connect their analysis to specific data and support their claims with actual examples from the text being analyzed.

The Difference between Analytical Essays and Critical Analysis Papers

While both analytical essays and critical analysis papers involve analyzing and evaluating texts, the main difference between them lies in the level of specificity and the depth of analysis. Analytical essays can be written on a wide range of topics and do not necessarily require a deep examination of the text. On the other hand, critical analysis papers are more focused and require a more in-depth analysis of the text being studied.

How to Write a Critical Analysis Paper

Writing a critical analysis paper can be challenging, but there are resources available to help writers understand the process. The Purdue OWL and YourDictionary both offer guides on how to write a critical analysis paper, which can provide step-by-step assistance in organizing and structuring the essay.

When writing a critical analysis paper, it is important to carefully read and thoroughly understand the text being analyzed. Take notes on important details, themes, and motifs that can support your analysis. Create an outline to organize your thoughts and ensure a clear and logical flow of ideas.

Within the body paragraphs, make sure to include specific examples from the text that illustrate your points. Use analysis and interpretation to explain the significance of these examples and how they connect to your thesis statement. It is also essential to provide evidence and support for your claims by referencing the actual text.

When concluding your critical analysis paper, take the opportunity to offer your final evaluation of the text. Summarize your main points and explain how your analysis contributes to a deeper understanding of the text. You can also discuss any broader implications or connections to other works or ideas.

Analysis Paper Example

The body paragraphs.

The body of the analysis paper is where writers provide the actual analysis and evaluation of the text. Each body paragraph should focus on a different aspect or element of the text and provide evidence to support the writer’s claims. In the example paper, each body paragraph may focus on a particular theme, character, or literary technique present in the text, providing examples and further analysis.

It is important for writers to understand that analytical essays differ from other types of academic papers. They require a more critical and in-depth approach to analyzing the chosen text. The body paragraphs should not simply summarize the text but rather provide an evaluation of its meaning and significance.

What Is an Analytical Essay: A Writing Guide With Examples

In academic writing, analytical essays are a common type of paper that students are often required to write. These essays involve analyzing and evaluating a particular topic or text, and are structured in a way that allows writers to present their findings and arguments in a logical and organized manner.

Understanding the Structure

The body paragraphs make up the main part of the essay and provide analysis and evaluation of the topic. Each paragraph should focus on a specific aspect or idea related to the thesis statement and provide supporting evidence or examples. It is essential to connect these paragraphs coherently and logically to maintain the flow of the essay.

Real-Life Examples

To further understand how to write an analytical essay, it can be helpful to examine some real-life examples. The Purdue OWL website and YourDictionary.com offer a wide range of sample analytical essays on various topics. These examples can provide guidance on how writers connect their analysis to the overall structure of the essay and demonstrate the use of evidence, critical thinking, and analysis in an analytical essay.

What is an analytical essay?

An analytical essay is a type of academic writing that requires the writer to analyze and interpret a particular subject or text. It involves breaking down the subject into different components and examining these parts to provide a thorough understanding and evaluation. The essay typically includes an introduction, body paragraphs with supporting evidence and analysis, and a conclusion.

What is the difference between an analytical essay and a critical analysis essay?

The main difference between an analytical essay and a critical analysis essay is the level of depth and focus. While an analytical essay involves analyzing and interpreting a subject, a critical analysis essay goes a step further and critiques the subject, questioning its strengths, weaknesses, and implications. A critical analysis essay often requires more in-depth research and a stronger argumentative approach.

How should I structure an analytical essay?

An analytical essay typically follows a specific structure. It starts with an introduction that provides background information and states the thesis statement. The body paragraphs then present evidence and analysis to support the thesis statement, with each paragraph focusing on a specific aspect. The essay ends with a conclusion that summarizes the main points and restates the thesis with a final insight or thought.

An analytical essay is a type of academic writing that requires the writer to thoroughly analyze a topic, issue, or piece of literature. It involves breaking down the subject into various components and examining them in a logical and systematic manner.

How is an analytical essay different from a critical analysis essay?

An analytical essay and a critical analysis essay are similar in many ways, but the main difference lies in the approach. While an analytical essay focuses on examining the topic or piece of literature objectively and presenting an analysis of its various aspects, a critical analysis essay involves not only providing an analysis but also offering a personal opinion or evaluation of the subject.

Analytical Essay Overview

An analytical essay is a type of academic writing that examines a topic, idea, or piece of literature in-depth. It involves breaking down the subject into its components, analyzing them, and presenting a well-structured argument or interpretation. 

The goal of an analytical essay is to explore the "how" and "why" of the subject rather than just describing it. Unlike an argumentative essay , an analytical does not include persuasion of the writer’s claim. It often requires evidence, critical thinking, and careful evaluation to support your thesis and provide insights. 

This essay type is commonly assigned in literature, history, and other academic disciplines to assess your ability to think critically and articulate your ideas clearly.

How To Write An Analytical Essay Outline?

Like every other academic writing, an analytical essay requires an organized structure for its content to be readable and understandable. In order to shape all the raw information, an outline is drafted.

An analytical essay outline is similar to the traditional  essay outline  of five paragraphs. According to this five-paragraph format, the essay is divided into the following sections:

• Introduction
• Body Paragraph 1
• Body Paragraph 2
• Body paragraph 3
• Conclusion 

The researched information about the specific topic needs to be organized. This is to make sure that the content is clear and effective for the readers. 

Read on to get a better idea of each section.

Analytical Essay Introduction

The importance and significance of the introduction of an essay can not be denied. An analytical essay introduction is the first section of the essay. In this part, the topic and author are introduced to the readers. 

The purpose of writing an  essay introduction  is to attract the readers to the topic. Also, motivate them to read the essay. The introduction lays the whole groundwork for your essay. So the more substantial the introduction, the more effective the paper is going to be.

The analytical essay introduction is based on two main elements:

• Thesis statement 

Just as the name suggests, a writer uses a hook statement to “hook” the audience to read further. A hook statement is an opening sentence of the introductory paragraph. It is a very important sentence as it grabs the reader’s attention towards the topic and the essay. 

A hook can be a sentence of any type. It can be humorous as well as factual. Depending on the essay topic, a writer can choose any form of an opening sentence. However, it goes with the theme and the topic of the essay. 

For example,

Thesis Statement

Following the hook comes the most critical element of an essay - the thesis statement. A thesis statement is the writer’s stance or argument on the chosen work. This is where the writer states and highlights the main argument of the essay topic. 

The thesis statement can be written by keeping in mind the original text’s goal and the writer’s analysis. 

When using a 5 paragraph format, a writer must provide a short supporting statement with the thesis statement. It is to show that the writer is going to back up the thesis. 

Analytical Essay Body Paragraphs

The body paragraphs of an essay support your claim by providing shreds of evidence. All the gathered and relevant information that justifies the argument is presented in this section.

The body section of an analytical essay should be divided into different paragraphs. The writer should discuss each point in a specific paragraph. It will make your essay logical and readable for the audience.

All of the paragraphs in the body section have four components to be covered:

• Topic Sentence -  A  topic sentence  is an opening sentence of a paragraph. This sentence is the claim or the important point that proves the thesis statement. Begin each of your paragraphs with a topic sentence. 
• Supporting Material -  The supporting material will back the claim and will provide detailed, researched information for your thesis statement. After writing a topic sentence, give evidence to prove it correct.
• Connection -  In order to tie your claim and evidence together, use a piece to follow the evidence. When using a quote or a phrase, make sure that you have stated its purpose or importance first.
• Transition -  After you have proved your claim, it is time to move on to the next paragraph or the claim. All the paragraphs in your essay must be connected and maintain a logical flow.

Each paragraph should be transitioned to make logical content. This transition will act as a bridge and will connect the previous paragraph with the next paragraph.

Analytical Essay Conclusion

The  essay conclusion  is the last section where all the discussion comes to an end. Here the writer restates the thesis statement and provides a short summary of the major points in the content. It will prove that the main argument is justified using the evidence for the readers.

For example, 

Analytical Essay Format

When it comes to formatting your analytical essay, adhering to specific guidelines is essential to ensure a professional presentation and clarity for your readers. Here are some key formatting guidelines to follow:

• Page Setup: Use standard letter-sized (8.5" x 11") paper with 1-inch margins on all sides.
• Font: Select a legible font, such as Times New Roman or Arial, and maintain consistency throughout the document.
• Font Size: Use a 12-point font size for the main text to ensure readability.
• Spacing: Double-space the entire essay, including the title, headings, and references.
• Title Page: Include a title page with the essay title, your name, course, instructor's name, and date. This information is typically centered and formatted according to your institution's guidelines.

By adhering to these formatting guidelines, you'll present your work professionally, making it easier for readers to engage with your analysis.

Analysis Essay

There are still a lot of things that man has yet to discover. We still have not reached the core of the earth nor the depths of the oceans and we are still on the process of exploration. The human mind is capable of understanding any complex task or idea.

In the quest of knowledge and information, we need to incorporate different strategies. That is why even in writing, we have to discover new styles and processes of expressing or telling a narrative. Essay writing is just one of the many tools that a writer uses in order to convey his/her thoughts and opinions.

What Is Analysis Essay?

An analysis essay is an article or a writing piece that involves the use of evaluation of an idea, an object, or an opinion. It involves a detailed assessment plan of a complex subject and break it down into smaller and simpler ideas in order to present its true meaning or essence.

In its true form, writing an analysis essay requires keen observation of the subject as well as unbiased judgment when presenting an idea. It avoids providing conclusions for essays or statements that may come from personal opinion or unformulated reasoning making this piece of literature helpful in presenting factual data and impartial inferences.

How to Structure Analysis Essay

There are two forms of an essay, one is formal and the other is informal. The former takes a standard structure while the latter is considered free essay writing where a writer can express or use any method as he/she pleases. While, for an analysis essay, it has to take the formal pattern. It should consist of an introduction, the body, and the conclusion or summary.

In addition to these three basic parts of an essay , you also need to make a title. It should be one that should follow or embody the whole point of your analysis as well as to give a preview of what it is all about.

Guidelines to Write Analysis Essay

There are many guidelines on how to write an effective essay, especially what that will present a detailed idea or interpretation of a more complex topic.

• Focus on the subject. Writing an analysis essay outline requires a writer to not get away from the main point. You need to avoid veering away even if the subject is too complex.
• Create an outline. You do not need to follow the basic pattern of essay writing. If you have created an outline that you are comfortable and you think is effective, use it.
• Establish an objective. You need to set a smart goal why you are doing an analysis essay. This helps you focus on what you are doing.

Benefits of Analysis Essay

Essay writing is a more common task that you see in schools. Students are often complaining when they are asked to write one especially an analysis essay. However, what we should understand is that writing an analysis essay has a lot of benefits that we might not be aware of.

First, you become better in writing effective essays . You will be exposed to a lot of thinking which is very important when you write.

The second one is it makes you a critical thinker. You become attentive to anything that crosses your path while at the same time being cautious of it. This attitude helps you in better decision-making.

Baltimore bridge collapse: a bridge engineer explains what happened, and what needs to change

When the container ship MV Dali, 300 metres long and massing around 100,000 tonnes, lost power and slammed into one of the support piers of the Francis Scott Key Bridge in Baltimore, the bridge collapsed in moments . Six people are presumed dead, several others injured, and the city and region are expecting a months-long logistical nightmare in the absence of a crucial transport link.

It was a shocking event, not only for the public but for bridge engineers like me. We work very hard to ensure bridges are safe, and overall the probability of being injured or worse in a bridge collapse remains even lower than the chance of being struck by lightning.

However, the images from Baltimore are a reminder that safety can’t be taken for granted. We need to remain vigilant.

So why did this bridge collapse? And, just as importantly, how might we make other bridges more safe against such collapse?

A 20th century bridge meets a 21st century ship

The Francis Scott Key Bridge was built through the mid 1970s and opened in 1977. The main structure over the navigation channel is a “continuous truss bridge” in three sections or spans.

The bridge rests on four supports, two of which sit each side of the navigable waterway. It is these two piers that are critical to protect against ship impacts.

And indeed, there were two layers of protection: a so-called “dolphin” structure made from concrete, and a fender. The dolphins are in the water about 100 metres upstream and downstream of the piers. They are intended to be sacrificed in the event of a wayward ship, absorbing its energy and being deformed in the process but keeping the ship from hitting the bridge itself.

The fender is the last layer of protection. It is a structure made of timber and reinforced concrete placed around the main piers. Again, it is intended to absorb the energy of any impact.

Fenders are not intended to absorb impacts from very large vessels . And so when the MV Dali, weighing more than 100,000 tonnes, made it past the protective dolphins, it was simply far too massive for the fender to withstand.

Read more: I've captained ships into tight ports like Baltimore, and this is how captains like me work with harbor pilots to avoid deadly collisions

Video recordings show a cloud of dust appearing just before the bridge collapsed, which may well have been the fender disintegrating as it was crushed by the ship.

Once the massive ship had made it past both the dolphin and the fender, the pier – one of the bridge’s four main supports – was simply incapable of resisting the impact. Given the size of the vessel and its likely speed of around 8 knots (15 kilometres per hour), the impact force would have been around 20,000 tonnes .

Bridges are getting safer

This was not the first time a ship hit the Francis Scott Bridge. There was another collision in 1980 , damaging a fender badly enough that it had to be replaced.

Around the world, 35 major bridge collapses resulting in fatalities were caused by collisions between 1960 and 2015, according to a 2018 report from the World Association for Waterborne Transport Infrastructure. Collisions between ships and bridges in the 1970s and early 1980s led to a significant improvement in the design rules for protecting bridges from impact.

Further impacts in the 1970s and early 1980s instigated significant improvements in the design rules for impact.

The International Association for Bridge and Structural Engineering’s Ship Collision with Bridges guide, published in 1993, and the American Association of State Highway and Transporation Officials’ Guide Specification and Commentary for Vessel Collision Design of Highway Bridges (1991) changed how bridges were designed.

In Australia, the Australian Standard for Bridge Design (published in 2017) requires designers to think about the biggest vessel likely to come along in the next 100 years, and what would happen if it were heading for any bridge pier at full speed. Designers need to consider the result of both head-on collisions and side-on, glancing blows. As a result, many newer bridges protect their piers with entire human-made islands.

Of course, these improvements came too late to influence the design of the Francis Scott Key Bridge itself.

Lessons from disaster

So what are the lessons apparent at this early stage?

First, it’s clear the protection measures in place for this bridge were not enough to handle this ship impact. Today’s cargo ships are much bigger than those of the 1970s, and it seems likely the Francis Scott Key Bridge was not designed with a collision like this in mind.

So one lesson is that we need to consider how the vessels near our bridges are changing. This means we cannot just accept the structure as it was built, but ensure the protection measures around our bridges are evolving alongside the ships around them.

Second, and more generally, we must remain vigilant in managing our bridges. I’ve written previously about the current level of safety of Australian bridges, but also about how we can do better.

This tragic event only emphasises the need to spend more on maintaining our ageing infrastructure. This is the only way to ensure it remains safe and functional for the demands we put on it today.

New York Takes Crucial Step Toward Making Congestion Pricing a Reality

The board of the Metropolitan Transportation Authority voted to approve a new $15 toll to drive into Manhattan. The plan still faces challenges from six lawsuits before it can begin in June.

By Winnie Hu and Ana Ley

New York City completed a crucial final step on Wednesday in a decades-long effort to become the first American city to roll out a comprehensive congestion pricing program, one that aims to push motorists out of their cars and onto mass transit by charging new tolls to drive into Midtown and Lower Manhattan.

The program could start as early as mid-June after the board of the Metropolitan Transportation Authority, the state agency that will install and manage the program, voted 11-to-1 to approve the final tolling rates, which will charge most passenger cars $15 a day to enter at 60th Street and below in Manhattan. The program is expected to reduce traffic and raise $1 billion annually for public transit improvements.

It was a historic moment for New York’s leaders and transportation advocates after decades of failed attempts to advance congestion pricing even as other gridlocked cities around the world, including London, Stockholm and Singapore, proved that similar programs could reduce traffic and pollution.

While other American cities have introduced related concepts by establishing toll roads or closing streets to traffic, the plan in New York is unmatched in ambition and scale.

Congestion pricing is expected to reduce the number of vehicles that enter Lower Manhattan by about 17 percent, according to a November study by an advisory committee reporting to the M.T.A. The report also said that the total number of miles driven in 28 counties across the region would be reduced.

“This was the right thing to do,” Janno Lieber, the authority’s chairman and chief executive, said after the vote. “New York has more traffic than any place in the United States, and now we’re doing something about it.”

Congestion pricing has long been a hard sell in New York, where many people commute by car from the boroughs outside of Manhattan and the suburbs, in part because some of them do not have access to public transit.

New York State legislators finally approved congestion pricing in 2019 after Gov. Andrew M. Cuomo helped push it through. A series of recent breakdowns in the city’s subway system had underscored the need for billions of dollars to update its aging infrastructure.

It has taken another five years to reach the starting line. Before the tolling program can begin, it must be reviewed by the Federal Highway Administration, which is expected to approve it.

Congestion pricing also faces legal challenges from six lawsuits that have been brought by elected officials and residents from across the New York region. Opponents have increasingly mobilized against the program in recent months, citing the cost of the tolls and the potential environmental effects from shifting traffic and pollution to other areas as drivers avoid the tolls.

A court hearing is scheduled for April 3 and 4 on a lawsuit brought by the State of New Jersey, which is seen as the most serious legal challenge. The mayor of Fort Lee, N.J., Mark J. Sokolich, has filed a related lawsuit.

Four more lawsuits have been brought in New York: by Ed Day, the Rockland County executive; by Vito Fossella, the Staten Island borough president, and the United Federation of Teachers; and by two separate groups of city residents.

Amid the litigation, M.T.A. officials have suspended some capital construction projects that were to be paid for by the program, and they said at a committee meeting on Monday that crucial work to modernize subway signals on the A and C lines had been delayed.

Nearly all the toll readers have been installed, and will automatically charge drivers for entering the designated congestion zone at 60th Street or below. There is no toll for leaving the zone or driving around in it. Through traffic on Franklin D. Roosevelt Drive and the West Side Highway will not be tolled.

Under the final tolling structure, which was based on recommendations by the advisory panel, most passenger vehicles will be charged $15 a day from 5 a.m. to 9 p.m. on weekdays, and from 9 a.m. to 9 p.m. on weekends. The toll will be $24 for small trucks and charter buses, and will rise to $36 for large trucks and tour buses. It will be $7.50 for motorcycles.

Those tolls will be discounted by 75 percent at night, dropping the cost for a passenger vehicle to $3.75.

Fares will go up by $1.25 for taxis and black car services, and by $2.50 for Uber and Lyft. Passengers will be responsible for paying the new fees, and they will be added to every ride that begins, ends or occurs within the congestion zone. There will be no nighttime discounts. (The new fees come on top of an existing congestion surcharge that was imposed on for-hire vehicles in 2019.)

The tolls will mostly be collected using the E-ZPass system. Electronic detection points have been placed at entrances and exits to the tolling zone. Drivers who do not use an E-ZPass will pay significantly higher fees — for instance, $22.50 instead of $15 during peak hours for passenger vehicles.

Emergency vehicles like fire trucks, ambulances and police cars, as well as vehicles carrying people with disabilities, were exempted from the new tolls under the state’s congestion pricing legislation .

As for discounts, low-income drivers who make less than $50,000 annually can apply to receive half off the daytime toll after their first 10 trips in a calendar month. In addition, low-income residents of the congestion zone who make less than $60,000 a year can apply for a state tax credit.

All drivers entering the zone directly from four tolled tunnels — the Lincoln, Holland, Hugh L. Carey and Queens-Midtown — will receive a “crossing credit” that will be applied against the daytime toll. The credit will be $5 round-trip for passenger vehicles, $12 for small trucks and intercity and charter buses, $20 for large trucks and tour buses, and $2.50 for motorcycles. No credits will be offered at night.

The perception and appreciation of food flavor depends on many interacting chemical compounds and external factors, and therefore proves challenging to understand and predict. Here, we combine extensive chemical and sensory analyses of 250 different beers to train machine learning models that allow predicting flavor and consumer appreciation. For each beer, we measure over 200 chemical properties, perform quantitative descriptive sensory analysis with a trained tasting panel and map data from over 180,000 consumer reviews to train 10 different machine learning models. The best-performing algorithm, Gradient Boosting, yields models that significantly outperform predictions based on conventional statistics and accurately predict complex food features and consumer appreciation from chemical profiles. Model dissection allows identifying specific and unexpected compounds as drivers of beer flavor and appreciation. Adding these compounds results in variants of commercial alcoholic and non-alcoholic beers with improved consumer appreciation. Together, our study reveals how big data and machine learning uncover complex links between food chemistry, flavor and consumer perception, and lays the foundation to develop novel, tailored foods with superior flavors.

Introduction

Predicting and understanding food perception and appreciation is one of the major challenges in food science. Accurate modeling of food flavor and appreciation could yield important opportunities for both producers and consumers, including quality control, product fingerprinting, counterfeit detection, spoilage detection, and the development of new products and product combinations (food pairing) 1 , 2 , 3 , 4 , 5 , 6 . Accurate models for flavor and consumer appreciation would contribute greatly to our scientific understanding of how humans perceive and appreciate flavor. Moreover, accurate predictive models would also facilitate and standardize existing food assessment methods and could supplement or replace assessments by trained and consumer tasting panels, which are variable, expensive and time-consuming 7 , 8 , 9 . Lastly, apart from providing objective, quantitative, accurate and contextual information that can help producers, models can also guide consumers in understanding their personal preferences 10 .

Despite the myriad of applications, predicting food flavor and appreciation from its chemical properties remains a largely elusive goal in sensory science, especially for complex food and beverages 11 , 12 . A key obstacle is the immense number of flavor-active chemicals underlying food flavor. Flavor compounds can vary widely in chemical structure and concentration, making them technically challenging and labor-intensive to quantify, even in the face of innovations in metabolomics, such as non-targeted metabolic fingerprinting 13 , 14 . Moreover, sensory analysis is perhaps even more complicated. Flavor perception is highly complex, resulting from hundreds of different molecules interacting at the physiochemical and sensorial level. Sensory perception is often non-linear, characterized by complex and concentration-dependent synergistic and antagonistic effects 15 , 16 , 17 , 18 , 19 , 20 , 21 that are further convoluted by the genetics, environment, culture and psychology of consumers 22 , 23 , 24 . Perceived flavor is therefore difficult to measure, with problems of sensitivity, accuracy, and reproducibility that can only be resolved by gathering sufficiently large datasets 25 . Trained tasting panels are considered the prime source of quality sensory data, but require meticulous training, are low throughput and high cost. Public databases containing consumer reviews of food products could provide a valuable alternative, especially for studying appreciation scores, which do not require formal training 25 . Public databases offer the advantage of amassing large amounts of data, increasing the statistical power to identify potential drivers of appreciation. However, public datasets suffer from biases, including a bias in the volunteers that contribute to the database, as well as confounding factors such as price, cult status and psychological conformity towards previous ratings of the product.

Classical multivariate statistics and machine learning methods have been used to predict flavor of specific compounds by, for example, linking structural properties of a compound to its potential biological activities or linking concentrations of specific compounds to sensory profiles 1 , 26 . Importantly, most previous studies focused on predicting organoleptic properties of single compounds (often based on their chemical structure) 27 , 28 , 29 , 30 , 31 , 32 , 33 , thus ignoring the fact that these compounds are present in a complex matrix in food or beverages and excluding complex interactions between compounds. Moreover, the classical statistics commonly used in sensory science 34 , 35 , 36 , 37 , 38 , 39 require a large sample size and sufficient variance amongst predictors to create accurate models. They are not fit for studying an extensive set of hundreds of interacting flavor compounds, since they are sensitive to outliers, have a high tendency to overfit and are less suited for non-linear and discontinuous relationships 40 .

In this study, we combine extensive chemical analyses and sensory data of a set of different commercial beers with machine learning approaches to develop models that predict taste, smell, mouthfeel and appreciation from compound concentrations. Beer is particularly suited to model the relationship between chemistry, flavor and appreciation. First, beer is a complex product, consisting of thousands of flavor compounds that partake in complex sensory interactions 41 , 42 , 43 . This chemical diversity arises from the raw materials (malt, yeast, hops, water and spices) and biochemical conversions during the brewing process (kilning, mashing, boiling, fermentation, maturation and aging) 44 , 45 . Second, the advent of the internet saw beer consumers embrace online review platforms, such as RateBeer (ZX Ventures, Anheuser-Busch InBev SA/NV) and BeerAdvocate (Next Glass, inc.). In this way, the beer community provides massive data sets of beer flavor and appreciation scores, creating extraordinarily large sensory databases to complement the analyses of our professional sensory panel. Specifically, we characterize over 200 chemical properties of 250 commercial beers, spread across 22 beer styles, and link these to the descriptive sensory profiling data of a 16-person in-house trained tasting panel and data acquired from over 180,000 public consumer reviews. These unique and extensive datasets enable us to train a suite of machine learning models to predict flavor and appreciation from a beer’s chemical profile. Dissection of the best-performing models allows us to pinpoint specific compounds as potential drivers of beer flavor and appreciation. Follow-up experiments confirm the importance of these compounds and ultimately allow us to significantly improve the flavor and appreciation of selected commercial beers. Together, our study represents a significant step towards understanding complex flavors and reinforces the value of machine learning to develop and refine complex foods. In this way, it represents a stepping stone for further computer-aided food engineering applications 46 .

To generate a comprehensive dataset on beer flavor, we selected 250 commercial Belgian beers across 22 different beer styles (Supplementary Fig.  S1 ). Beers with ≤ 4.2% alcohol by volume (ABV) were classified as non-alcoholic and low-alcoholic. Blonds and Tripels constitute a significant portion of the dataset (12.4% and 11.2%, respectively) reflecting their presence on the Belgian beer market and the heterogeneity of beers within these styles. By contrast, lager beers are less diverse and dominated by a handful of brands. Rare styles such as Brut or Faro make up only a small fraction of the dataset (2% and 1%, respectively) because fewer of these beers are produced and because they are dominated by distinct characteristics in terms of flavor and chemical composition.

Extensive analysis identifies relationships between chemical compounds in beer

For each beer, we measured 226 different chemical properties, including common brewing parameters such as alcohol content, iso-alpha acids, pH, sugar concentration 47 , and over 200 flavor compounds (Methods, Supplementary Table  S1 ). A large portion (37.2%) are terpenoids arising from hopping, responsible for herbal and fruity flavors 16 , 48 . A second major category are yeast metabolites, such as esters and alcohols, that result in fruity and solvent notes 48 , 49 , 50 . Other measured compounds are primarily derived from malt, or other microbes such as non- Saccharomyces yeasts and bacteria (‘wild flora’). Compounds that arise from spices or staling are labeled under ‘Others’. Five attributes (caloric value, total acids and total ester, hop aroma and sulfur compounds) are calculated from multiple individually measured compounds.

As a first step in identifying relationships between chemical properties, we determined correlations between the concentrations of the compounds (Fig.  1 , upper panel, Supplementary Data  1 and 2 , and Supplementary Fig.  S2 . For the sake of clarity, only a subset of the measured compounds is shown in Fig.  1 ). Compounds of the same origin typically show a positive correlation, while absence of correlation hints at parameters varying independently. For example, the hop aroma compounds citronellol, and alpha-terpineol show moderate correlations with each other (Spearman’s rho=0.39 and 0.57), but not with the bittering hop component iso-alpha acids (Spearman’s rho=0.16 and −0.07). This illustrates how brewers can independently modify hop aroma and bitterness by selecting hop varieties and dosage time. If hops are added early in the boiling phase, chemical conversions increase bitterness while aromas evaporate, conversely, late addition of hops preserves aroma but limits bitterness 51 . Similarly, hop-derived iso-alpha acids show a strong anti-correlation with lactic acid and acetic acid, likely reflecting growth inhibition of lactic acid and acetic acid bacteria, or the consequent use of fewer hops in sour beer styles, such as West Flanders ales and Fruit beers, that rely on these bacteria for their distinct flavors 52 . Finally, yeast-derived esters (ethyl acetate, ethyl decanoate, ethyl hexanoate, ethyl octanoate) and alcohols (ethanol, isoamyl alcohol, isobutanol, and glycerol), correlate with Spearman coefficients above 0.5, suggesting that these secondary metabolites are correlated with the yeast genetic background and/or fermentation parameters and may be difficult to influence individually, although the choice of yeast strain may offer some control 53 .

Spearman rank correlations are shown. Descriptors are grouped according to their origin (malt (blue), hops (green), yeast (red), wild flora (yellow), Others (black)), and sensory aspect (aroma, taste, palate, and overall appreciation). Please note that for the chemical compounds, for the sake of clarity, only a subset of the total number of measured compounds is shown, with an emphasis on the key compounds for each source. For more details, see the main text and Methods section. Chemical data can be found in Supplementary Data  1 , correlations between all chemical compounds are depicted in Supplementary Fig.  S2 and correlation values can be found in Supplementary Data  2 . See Supplementary Data  4 for sensory panel assessments and Supplementary Data  5 for correlation values between all sensory descriptors.

Interestingly, different beer styles show distinct patterns for some flavor compounds (Supplementary Fig.  S3 ). These observations agree with expectations for key beer styles, and serve as a control for our measurements. For instance, Stouts generally show high values for color (darker), while hoppy beers contain elevated levels of iso-alpha acids, compounds associated with bitter hop taste. Acetic and lactic acid are not prevalent in most beers, with notable exceptions such as Kriek, Lambic, Faro, West Flanders ales and Flanders Old Brown, which use acid-producing bacteria ( Lactobacillus and Pediococcus ) or unconventional yeast ( Brettanomyces ) 54 , 55 . Glycerol, ethanol and esters show similar distributions across all beer styles, reflecting their common origin as products of yeast metabolism during fermentation 45 , 53 . Finally, low/no-alcohol beers contain low concentrations of glycerol and esters. This is in line with the production process for most of the low/no-alcohol beers in our dataset, which are produced through limiting fermentation or by stripping away alcohol via evaporation or dialysis, with both methods having the unintended side-effect of reducing the amount of flavor compounds in the final beer 56 , 57 .

Besides expected associations, our data also reveals less trivial associations between beer styles and specific parameters. For example, geraniol and citronellol, two monoterpenoids responsible for citrus, floral and rose flavors and characteristic of Citra hops, are found in relatively high amounts in Christmas, Saison, and Brett/co-fermented beers, where they may originate from terpenoid-rich spices such as coriander seeds instead of hops 58 .

Tasting panel assessments reveal sensorial relationships in beer

To assess the sensory profile of each beer, a trained tasting panel evaluated each of the 250 beers for 50 sensory attributes, including different hop, malt and yeast flavors, off-flavors and spices. Panelists used a tasting sheet (Supplementary Data  3 ) to score the different attributes. Panel consistency was evaluated by repeating 12 samples across different sessions and performing ANOVA. In 95% of cases no significant difference was found across sessions ( p  > 0.05), indicating good panel consistency (Supplementary Table  S2 ).

Aroma and taste perception reported by the trained panel are often linked (Fig.  1 , bottom left panel and Supplementary Data  4 and 5 ), with high correlations between hops aroma and taste (Spearman’s rho=0.83). Bitter taste was found to correlate with hop aroma and taste in general (Spearman’s rho=0.80 and 0.69), and particularly with “grassy” noble hops (Spearman’s rho=0.75). Barnyard flavor, most often associated with sour beers, is identified together with stale hops (Spearman’s rho=0.97) that are used in these beers. Lactic and acetic acid, which often co-occur, are correlated (Spearman’s rho=0.66). Interestingly, sweetness and bitterness are anti-correlated (Spearman’s rho = −0.48), confirming the hypothesis that they mask each other 59 , 60 . Beer body is highly correlated with alcohol (Spearman’s rho = 0.79), and overall appreciation is found to correlate with multiple aspects that describe beer mouthfeel (alcohol, carbonation; Spearman’s rho= 0.32, 0.39), as well as with hop and ester aroma intensity (Spearman’s rho=0.39 and 0.35).

Similar to the chemical analyses, sensorial analyses confirmed typical features of specific beer styles (Supplementary Fig.  S4 ). For example, sour beers (Faro, Flanders Old Brown, Fruit beer, Kriek, Lambic, West Flanders ale) were rated acidic, with flavors of both acetic and lactic acid. Hoppy beers were found to be bitter and showed hop-associated aromas like citrus and tropical fruit. Malt taste is most detected among scotch, stout/porters, and strong ales, while low/no-alcohol beers, which often have a reputation for being ‘worty’ (reminiscent of unfermented, sweet malt extract) appear in the middle. Unsurprisingly, hop aromas are most strongly detected among hoppy beers. Like its chemical counterpart (Supplementary Fig.  S3 ), acidity shows a right-skewed distribution, with the most acidic beers being Krieks, Lambics, and West Flanders ales.

Tasting panel assessments of specific flavors correlate with chemical composition

We find that the concentrations of several chemical compounds strongly correlate with specific aroma or taste, as evaluated by the tasting panel (Fig.  2 , Supplementary Fig.  S5 , Supplementary Data  6 ). In some cases, these correlations confirm expectations and serve as a useful control for data quality. For example, iso-alpha acids, the bittering compounds in hops, strongly correlate with bitterness (Spearman’s rho=0.68), while ethanol and glycerol correlate with tasters’ perceptions of alcohol and body, the mouthfeel sensation of fullness (Spearman’s rho=0.82/0.62 and 0.72/0.57 respectively) and darker color from roasted malts is a good indication of malt perception (Spearman’s rho=0.54).

Heatmap colors indicate Spearman’s Rho. Axes are organized according to sensory categories (aroma, taste, mouthfeel, overall), chemical categories and chemical sources in beer (malt (blue), hops (green), yeast (red), wild flora (yellow), Others (black)). See Supplementary Data  6 for all correlation values.

Interestingly, for some relationships between chemical compounds and perceived flavor, correlations are weaker than expected. For example, the rose-smelling phenethyl acetate only weakly correlates with floral aroma. This hints at more complex relationships and interactions between compounds and suggests a need for a more complex model than simple correlations. Lastly, we uncovered unexpected correlations. For instance, the esters ethyl decanoate and ethyl octanoate appear to correlate slightly with hop perception and bitterness, possibly due to their fruity flavor. Iron is anti-correlated with hop aromas and bitterness, most likely because it is also anti-correlated with iso-alpha acids. This could be a sign of metal chelation of hop acids 61 , given that our analyses measure unbound hop acids and total iron content, or could result from the higher iron content in dark and Fruit beers, which typically have less hoppy and bitter flavors 62 .

Public consumer reviews complement expert panel data

To complement and expand the sensory data of our trained tasting panel, we collected 180,000 reviews of our 250 beers from the online consumer review platform RateBeer. This provided numerical scores for beer appearance, aroma, taste, palate, overall quality as well as the average overall score.

Public datasets are known to suffer from biases, such as price, cult status and psychological conformity towards previous ratings of a product. For example, prices correlate with appreciation scores for these online consumer reviews (rho=0.49, Supplementary Fig.  S6 ), but not for our trained tasting panel (rho=0.19). This suggests that prices affect consumer appreciation, which has been reported in wine 63 , while blind tastings are unaffected. Moreover, we observe that some beer styles, like lagers and non-alcoholic beers, generally receive lower scores, reflecting that online reviewers are mostly beer aficionados with a preference for specialty beers over lager beers. In general, we find a modest correlation between our trained panel’s overall appreciation score and the online consumer appreciation scores (Fig.  3 , rho=0.29). Apart from the aforementioned biases in the online datasets, serving temperature, sample freshness and surroundings, which are all tightly controlled during the tasting panel sessions, can vary tremendously across online consumers and can further contribute to (among others, appreciation) differences between the two categories of tasters. Importantly, in contrast to the overall appreciation scores, for many sensory aspects the results from the professional panel correlated well with results obtained from RateBeer reviews. Correlations were highest for features that are relatively easy to recognize even for untrained tasters, like bitterness, sweetness, alcohol and malt aroma (Fig.  3 and below).

RateBeer text mining results can be found in Supplementary Data  7 . Rho values shown are Spearman correlation values, with asterisks indicating significant correlations ( p  < 0.05, two-sided). All p values were smaller than 0.001, except for Esters aroma (0.0553), Esters taste (0.3275), Esters aroma—banana (0.0019), Coriander (0.0508) and Diacetyl (0.0134).

Besides collecting consumer appreciation from these online reviews, we developed automated text analysis tools to gather additional data from review texts (Supplementary Data  7 ). Processing review texts on the RateBeer database yielded comparable results to the scores given by the trained panel for many common sensory aspects, including acidity, bitterness, sweetness, alcohol, malt, and hop tastes (Fig.  3 ). This is in line with what would be expected, since these attributes require less training for accurate assessment and are less influenced by environmental factors such as temperature, serving glass and odors in the environment. Consumer reviews also correlate well with our trained panel for 4-vinyl guaiacol, a compound associated with a very characteristic aroma. By contrast, correlations for more specific aromas like ester, coriander or diacetyl are underrepresented in the online reviews, underscoring the importance of using a trained tasting panel and standardized tasting sheets with explicit factors to be scored for evaluating specific aspects of a beer. Taken together, our results suggest that public reviews are trustworthy for some, but not all, flavor features and can complement or substitute taste panel data for these sensory aspects.

Models can predict beer sensory profiles from chemical data

The rich datasets of chemical analyses, tasting panel assessments and public reviews gathered in the first part of this study provided us with a unique opportunity to develop predictive models that link chemical data to sensorial features. Given the complexity of beer flavor, basic statistical tools such as correlations or linear regression may not always be the most suitable for making accurate predictions. Instead, we applied different machine learning models that can model both simple linear and complex interactive relationships. Specifically, we constructed a set of regression models to predict (a) trained panel scores for beer flavor and quality and (b) public reviews’ appreciation scores from beer chemical profiles. We trained and tested 10 different models (Methods), 3 linear regression-based models (simple linear regression with first-order interactions (LR), lasso regression with first-order interactions (Lasso), partial least squares regressor (PLSR)), 5 decision tree models (AdaBoost regressor (ABR), extra trees (ET), gradient boosting regressor (GBR), random forest (RF) and XGBoost regressor (XGBR)), 1 support vector regression (SVR), and 1 artificial neural network (ANN) model.

To compare the performance of our machine learning models, the dataset was randomly split into a training and test set, stratified by beer style. After a model was trained on data in the training set, its performance was evaluated on its ability to predict the test dataset obtained from multi-output models (based on the coefficient of determination, see Methods). Additionally, individual-attribute models were ranked per descriptor and the average rank was calculated, as proposed by Korneva et al. 64 . Importantly, both ways of evaluating the models’ performance agreed in general. Performance of the different models varied (Table  1 ). It should be noted that all models perform better at predicting RateBeer results than results from our trained tasting panel. One reason could be that sensory data is inherently variable, and this variability is averaged out with the large number of public reviews from RateBeer. Additionally, all tree-based models perform better at predicting taste than aroma. Linear models (LR) performed particularly poorly, with negative R 2 values, due to severe overfitting (training set R 2  = 1). Overfitting is a common issue in linear models with many parameters and limited samples, especially with interaction terms further amplifying the number of parameters. L1 regularization (Lasso) successfully overcomes this overfitting, out-competing multiple tree-based models on the RateBeer dataset. Similarly, the dimensionality reduction of PLSR avoids overfitting and improves performance, to some extent. Still, tree-based models (ABR, ET, GBR, RF and XGBR) show the best performance, out-competing the linear models (LR, Lasso, PLSR) commonly used in sensory science 65 .

GBR models showed the best overall performance in predicting sensory responses from chemical information, with R 2 values up to 0.75 depending on the predicted sensory feature (Supplementary Table  S4 ). The GBR models predict consumer appreciation (RateBeer) better than our trained panel’s appreciation (R 2 value of 0.67 compared to R 2 value of 0.09) (Supplementary Table  S3 and Supplementary Table  S4 ). ANN models showed intermediate performance, likely because neural networks typically perform best with larger datasets 66 . The SVR shows intermediate performance, mostly due to the weak predictions of specific attributes that lower the overall performance (Supplementary Table  S4 ).

Model dissection identifies specific, unexpected compounds as drivers of consumer appreciation

Next, we leveraged our models to infer important contributors to sensory perception and consumer appreciation. Consumer preference is a crucial sensory aspects, because a product that shows low consumer appreciation scores often does not succeed commercially 25 . Additionally, the requirement for a large number of representative evaluators makes consumer trials one of the more costly and time-consuming aspects of product development. Hence, a model for predicting chemical drivers of overall appreciation would be a welcome addition to the available toolbox for food development and optimization.

Since GBR models on our RateBeer dataset showed the best overall performance, we focused on these models. Specifically, we used two approaches to identify important contributors. First, rankings of the most important predictors for each sensorial trait in the GBR models were obtained based on impurity-based feature importance (mean decrease in impurity). High-ranked parameters were hypothesized to be either the true causal chemical properties underlying the trait, to correlate with the actual causal properties, or to take part in sensory interactions affecting the trait 67 (Fig.  4A ). In a second approach, we used SHAP 68 to determine which parameters contributed most to the model for making predictions of consumer appreciation (Fig.  4B ). SHAP calculates parameter contributions to model predictions on a per-sample basis, which can be aggregated into an importance score.

A The impurity-based feature importance (mean deviance in impurity, MDI) calculated from the Gradient Boosting Regression (GBR) model predicting RateBeer appreciation scores. The top 15 highest ranked chemical properties are shown. B SHAP summary plot for the top 15 parameters contributing to our GBR model. Each point on the graph represents a sample from our dataset. The color represents the concentration of that parameter, with bluer colors representing low values and redder colors representing higher values. Greater absolute values on the horizontal axis indicate a higher impact of the parameter on the prediction of the model. C Spearman correlations between the 15 most important chemical properties and consumer overall appreciation. Numbers indicate the Spearman Rho correlation coefficient, and the rank of this correlation compared to all other correlations. The top 15 important compounds were determined using SHAP (panel B).

Both approaches identified ethyl acetate as the most predictive parameter for beer appreciation (Fig.  4 ). Ethyl acetate is the most abundant ester in beer with a typical ‘fruity’, ‘solvent’ and ‘alcoholic’ flavor, but is often considered less important than other esters like isoamyl acetate. The second most important parameter identified by SHAP is ethanol, the most abundant beer compound after water. Apart from directly contributing to beer flavor and mouthfeel, ethanol drastically influences the physical properties of beer, dictating how easily volatile compounds escape the beer matrix to contribute to beer aroma 69 . Importantly, it should also be noted that the importance of ethanol for appreciation is likely inflated by the very low appreciation scores of non-alcoholic beers (Supplementary Fig.  S4 ). Despite not often being considered a driver of beer appreciation, protein level also ranks highly in both approaches, possibly due to its effect on mouthfeel and body 70 . Lactic acid, which contributes to the tart taste of sour beers, is the fourth most important parameter identified by SHAP, possibly due to the generally high appreciation of sour beers in our dataset.

Interestingly, some of the most important predictive parameters for our model are not well-established as beer flavors or are even commonly regarded as being negative for beer quality. For example, our models identify methanethiol and ethyl phenyl acetate, an ester commonly linked to beer staling 71 , as a key factor contributing to beer appreciation. Although there is no doubt that high concentrations of these compounds are considered unpleasant, the positive effects of modest concentrations are not yet known 72 , 73 .

To compare our approach to conventional statistics, we evaluated how well the 15 most important SHAP-derived parameters correlate with consumer appreciation (Fig.  4C ). Interestingly, only 6 of the properties derived by SHAP rank amongst the top 15 most correlated parameters. For some chemical compounds, the correlations are so low that they would have likely been considered unimportant. For example, lactic acid, the fourth most important parameter, shows a bimodal distribution for appreciation, with sour beers forming a separate cluster, that is missed entirely by the Spearman correlation. Additionally, the correlation plots reveal outliers, emphasizing the need for robust analysis tools. Together, this highlights the need for alternative models, like the Gradient Boosting model, that better grasp the complexity of (beer) flavor.

Finally, to observe the relationships between these chemical properties and their predicted targets, partial dependence plots were constructed for the six most important predictors of consumer appreciation 74 , 75 , 76 (Supplementary Fig.  S7 ). One-way partial dependence plots show how a change in concentration affects the predicted appreciation. These plots reveal an important limitation of our models: appreciation predictions remain constant at ever-increasing concentrations. This implies that once a threshold concentration is reached, further increasing the concentration does not affect appreciation. This is false, as it is well-documented that certain compounds become unpleasant at high concentrations, including ethyl acetate (‘nail polish’) 77 and methanethiol (‘sulfury’ and ‘rotten cabbage’) 78 . The inability of our models to grasp that flavor compounds have optimal levels, above which they become negative, is a consequence of working with commercial beer brands where (off-)flavors are rarely too high to negatively impact the product. The two-way partial dependence plots show how changing the concentration of two compounds influences predicted appreciation, visualizing their interactions (Supplementary Fig.  S7 ). In our case, the top 5 parameters are dominated by additive or synergistic interactions, with high concentrations for both compounds resulting in the highest predicted appreciation.

To assess the robustness of our best-performing models and model predictions, we performed 100 iterations of the GBR, RF and ET models. In general, all iterations of the models yielded similar performance (Supplementary Fig.  S8 ). Moreover, the main predictors (including the top predictors ethanol and ethyl acetate) remained virtually the same, especially for GBR and RF. For the iterations of the ET model, we did observe more variation in the top predictors, which is likely a consequence of the model’s inherent random architecture in combination with co-correlations between certain predictors. However, even in this case, several of the top predictors (ethanol and ethyl acetate) remain unchanged, although their rank in importance changes (Supplementary Fig.  S8 ).

Next, we investigated if a combination of RateBeer and trained panel data into one consolidated dataset would lead to stronger models, under the hypothesis that such a model would suffer less from bias in the datasets. A GBR model was trained to predict appreciation on the combined dataset. This model underperformed compared to the RateBeer model, both in the native case and when including a dataset identifier (R 2  = 0.67, 0.26 and 0.42 respectively). For the latter, the dataset identifier is the most important feature (Supplementary Fig.  S9 ), while most of the feature importance remains unchanged, with ethyl acetate and ethanol ranking highest, like in the original model trained only on RateBeer data. It seems that the large variation in the panel dataset introduces noise, weakening the models’ performances and reliability. In addition, it seems reasonable to assume that both datasets are fundamentally different, with the panel dataset obtained by blind tastings by a trained professional panel.

Lastly, we evaluated whether beer style identifiers would further enhance the model’s performance. A GBR model was trained with parameters that explicitly encoded the styles of the samples. This did not improve model performance (R2 = 0.66 with style information vs R2 = 0.67). The most important chemical features are consistent with the model trained without style information (eg. ethanol and ethyl acetate), and with the exception of the most preferred (strong ale) and least preferred (low/no-alcohol) styles, none of the styles were among the most important features (Supplementary Fig.  S9 , Supplementary Table  S5 and S6 ). This is likely due to a combination of style-specific chemical signatures, such as iso-alpha acids and lactic acid, that implicitly convey style information to the original models, as well as the low number of samples belonging to some styles, making it difficult for the model to learn style-specific patterns. Moreover, beer styles are not rigorously defined, with some styles overlapping in features and some beers being misattributed to a specific style, all of which leads to more noise in models that use style parameters.

Model validation

To test if our predictive models give insight into beer appreciation, we set up experiments aimed at improving existing commercial beers. We specifically selected overall appreciation as the trait to be examined because of its complexity and commercial relevance. Beer flavor comprises a complex bouquet rather than single aromas and tastes 53 . Hence, adding a single compound to the extent that a difference is noticeable may lead to an unbalanced, artificial flavor. Therefore, we evaluated the effect of combinations of compounds. Because Blond beers represent the most extensive style in our dataset, we selected a beer from this style as the starting material for these experiments (Beer 64 in Supplementary Data  1 ).

In the first set of experiments, we adjusted the concentrations of compounds that made up the most important predictors of overall appreciation (ethyl acetate, ethanol, lactic acid, ethyl phenyl acetate) together with correlated compounds (ethyl hexanoate, isoamyl acetate, glycerol), bringing them up to 95 th percentile ethanol-normalized concentrations (Methods) within the Blond group (‘Spiked’ concentration in Fig.  5A ). Compared to controls, the spiked beers were found to have significantly improved overall appreciation among trained panelists, with panelist noting increased intensity of ester flavors, sweetness, alcohol, and body fullness (Fig.  5B ). To disentangle the contribution of ethanol to these results, a second experiment was performed without the addition of ethanol. This resulted in a similar outcome, including increased perception of alcohol and overall appreciation.

Adding the top chemical compounds, identified as best predictors of appreciation by our model, into poorly appreciated beers results in increased appreciation from our trained panel. Results of sensory tests between base beers and those spiked with compounds identified as the best predictors by the model. A Blond and Non/Low-alcohol (0.0% ABV) base beers were brought up to 95th-percentile ethanol-normalized concentrations within each style. B For each sensory attribute, tasters indicated the more intense sample and selected the sample they preferred. The numbers above the bars correspond to the p values that indicate significant changes in perceived flavor (two-sided binomial test: alpha 0.05, n  = 20 or 13).

In a last experiment, we tested whether using the model’s predictions can boost the appreciation of a non-alcoholic beer (beer 223 in Supplementary Data  1 ). Again, the addition of a mixture of predicted compounds (omitting ethanol, in this case) resulted in a significant increase in appreciation, body, ester flavor and sweetness.

Predicting flavor and consumer appreciation from chemical composition is one of the ultimate goals of sensory science. A reliable, systematic and unbiased way to link chemical profiles to flavor and food appreciation would be a significant asset to the food and beverage industry. Such tools would substantially aid in quality control and recipe development, offer an efficient and cost-effective alternative to pilot studies and consumer trials and would ultimately allow food manufacturers to produce superior, tailor-made products that better meet the demands of specific consumer groups more efficiently.

A limited set of studies have previously tried, to varying degrees of success, to predict beer flavor and beer popularity based on (a limited set of) chemical compounds and flavors 79 , 80 . Current sensitive, high-throughput technologies allow measuring an unprecedented number of chemical compounds and properties in a large set of samples, yielding a dataset that can train models that help close the gaps between chemistry and flavor, even for a complex natural product like beer. To our knowledge, no previous research gathered data at this scale (250 samples, 226 chemical parameters, 50 sensory attributes and 5 consumer scores) to disentangle and validate the chemical aspects driving beer preference using various machine-learning techniques. We find that modern machine learning models outperform conventional statistical tools, such as correlations and linear models, and can successfully predict flavor appreciation from chemical composition. This could be attributed to the natural incorporation of interactions and non-linear or discontinuous effects in machine learning models, which are not easily grasped by the linear model architecture. While linear models and partial least squares regression represent the most widespread statistical approaches in sensory science, in part because they allow interpretation 65 , 81 , 82 , modern machine learning methods allow for building better predictive models while preserving the possibility to dissect and exploit the underlying patterns. Of the 10 different models we trained, tree-based models, such as our best performing GBR, showed the best overall performance in predicting sensory responses from chemical information, outcompeting artificial neural networks. This agrees with previous reports for models trained on tabular data 83 . Our results are in line with the findings of Colantonio et al. who also identified the gradient boosting architecture as performing best at predicting appreciation and flavor (of tomatoes and blueberries, in their specific study) 26 . Importantly, besides our larger experimental scale, we were able to directly confirm our models’ predictions in vivo.

Our study confirms that flavor compound concentration does not always correlate with perception, suggesting complex interactions that are often missed by more conventional statistics and simple models. Specifically, we find that tree-based algorithms may perform best in developing models that link complex food chemistry with aroma. Furthermore, we show that massive datasets of untrained consumer reviews provide a valuable source of data, that can complement or even replace trained tasting panels, especially for appreciation and basic flavors, such as sweetness and bitterness. This holds despite biases that are known to occur in such datasets, such as price or conformity bias. Moreover, GBR models predict taste better than aroma. This is likely because taste (e.g. bitterness) often directly relates to the corresponding chemical measurements (e.g., iso-alpha acids), whereas such a link is less clear for aromas, which often result from the interplay between multiple volatile compounds. We also find that our models are best at predicting acidity and alcohol, likely because there is a direct relation between the measured chemical compounds (acids and ethanol) and the corresponding perceived sensorial attribute (acidity and alcohol), and because even untrained consumers are generally able to recognize these flavors and aromas.

The predictions of our final models, trained on review data, hold even for blind tastings with small groups of trained tasters, as demonstrated by our ability to validate specific compounds as drivers of beer flavor and appreciation. Since adding a single compound to the extent of a noticeable difference may result in an unbalanced flavor profile, we specifically tested our identified key drivers as a combination of compounds. While this approach does not allow us to validate if a particular single compound would affect flavor and/or appreciation, our experiments do show that this combination of compounds increases consumer appreciation.

It is important to stress that, while it represents an important step forward, our approach still has several major limitations. A key weakness of the GBR model architecture is that amongst co-correlating variables, the largest main effect is consistently preferred for model building. As a result, co-correlating variables often have artificially low importance scores, both for impurity and SHAP-based methods, like we observed in the comparison to the more randomized Extra Trees models. This implies that chemicals identified as key drivers of a specific sensory feature by GBR might not be the true causative compounds, but rather co-correlate with the actual causative chemical. For example, the high importance of ethyl acetate could be (partially) attributed to the total ester content, ethanol or ethyl hexanoate (rho=0.77, rho=0.72 and rho=0.68), while ethyl phenylacetate could hide the importance of prenyl isobutyrate and ethyl benzoate (rho=0.77 and rho=0.76). Expanding our GBR model to include beer style as a parameter did not yield additional power or insight. This is likely due to style-specific chemical signatures, such as iso-alpha acids and lactic acid, that implicitly convey style information to the original model, as well as the smaller sample size per style, limiting the power to uncover style-specific patterns. This can be partly attributed to the curse of dimensionality, where the high number of parameters results in the models mainly incorporating single parameter effects, rather than complex interactions such as style-dependent effects 67 . A larger number of samples may overcome some of these limitations and offer more insight into style-specific effects. On the other hand, beer style is not a rigid scientific classification, and beers within one style often differ a lot, which further complicates the analysis of style as a model factor.

Our study is limited to beers from Belgian breweries. Although these beers cover a large portion of the beer styles available globally, some beer styles and consumer patterns may be missing, while other features might be overrepresented. For example, many Belgian ales exhibit yeast-driven flavor profiles, which is reflected in the chemical drivers of appreciation discovered by this study. In future work, expanding the scope to include diverse markets and beer styles could lead to the identification of even more drivers of appreciation and better models for special niche products that were not present in our beer set.

In addition to inherent limitations of GBR models, there are also some limitations associated with studying food aroma. Even if our chemical analyses measured most of the known aroma compounds, the total number of flavor compounds in complex foods like beer is still larger than the subset we were able to measure in this study. For example, hop-derived thiols, that influence flavor at very low concentrations, are notoriously difficult to measure in a high-throughput experiment. Moreover, consumer perception remains subjective and prone to biases that are difficult to avoid. It is also important to stress that the models are still immature and that more extensive datasets will be crucial for developing more complete models in the future. Besides more samples and parameters, our dataset does not include any demographic information about the tasters. Including such data could lead to better models that grasp external factors like age and culture. Another limitation is that our set of beers consists of high-quality end-products and lacks beers that are unfit for sale, which limits the current model in accurately predicting products that are appreciated very badly. Finally, while models could be readily applied in quality control, their use in sensory science and product development is restrained by their inability to discern causal relationships. Given that the models cannot distinguish compounds that genuinely drive consumer perception from those that merely correlate, validation experiments are essential to identify true causative compounds.

Despite the inherent limitations, dissection of our models enabled us to pinpoint specific molecules as potential drivers of beer aroma and consumer appreciation, including compounds that were unexpected and would not have been identified using standard approaches. Important drivers of beer appreciation uncovered by our models include protein levels, ethyl acetate, ethyl phenyl acetate and lactic acid. Currently, many brewers already use lactic acid to acidify their brewing water and ensure optimal pH for enzymatic activity during the mashing process. Our results suggest that adding lactic acid can also improve beer appreciation, although its individual effect remains to be tested. Interestingly, ethanol appears to be unnecessary to improve beer appreciation, both for blond beer and alcohol-free beer. Given the growing consumer interest in alcohol-free beer, with a predicted annual market growth of >7% 84 , it is relevant for brewers to know what compounds can further increase consumer appreciation of these beers. Hence, our model may readily provide avenues to further improve the flavor and consumer appreciation of both alcoholic and non-alcoholic beers, which is generally considered one of the key challenges for future beer production.

Whereas we see a direct implementation of our results for the development of superior alcohol-free beverages and other food products, our study can also serve as a stepping stone for the development of novel alcohol-containing beverages. We want to echo the growing body of scientific evidence for the negative effects of alcohol consumption, both on the individual level by the mutagenic, teratogenic and carcinogenic effects of ethanol 85 , 86 , as well as the burden on society caused by alcohol abuse and addiction. We encourage the use of our results for the production of healthier, tastier products, including novel and improved beverages with lower alcohol contents. Furthermore, we strongly discourage the use of these technologies to improve the appreciation or addictive properties of harmful substances.

The present work demonstrates that despite some important remaining hurdles, combining the latest developments in chemical analyses, sensory analysis and modern machine learning methods offers exciting avenues for food chemistry and engineering. Soon, these tools may provide solutions in quality control and recipe development, as well as new approaches to sensory science and flavor research.

Beer selection

250 commercial Belgian beers were selected to cover the broad diversity of beer styles and corresponding diversity in chemical composition and aroma. See Supplementary Fig.  S1 .

Chemical dataset

Sample preparation.

Beers within their expiration date were purchased from commercial retailers. Samples were prepared in biological duplicates at room temperature, unless explicitly stated otherwise. Bottle pressure was measured with a manual pressure device (Steinfurth Mess-Systeme GmbH) and used to calculate CO 2 concentration. The beer was poured through two filter papers (Macherey-Nagel, 500713032 MN 713 ¼) to remove carbon dioxide and prevent spontaneous foaming. Samples were then prepared for measurements by targeted Headspace-Gas Chromatography-Flame Ionization Detector/Flame Photometric Detector (HS-GC-FID/FPD), Headspace-Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry (HS-SPME-GC-MS), colorimetric analysis, enzymatic analysis, Near-Infrared (NIR) analysis, as described in the sections below. The mean values of biological duplicates are reported for each compound.

HS-GC-FID/FPD

HS-GC-FID/FPD (Shimadzu GC 2010 Plus) was used to measure higher alcohols, acetaldehyde, esters, 4-vinyl guaicol, and sulfur compounds. Each measurement comprised 5 ml of sample pipetted into a 20 ml glass vial containing 1.75 g NaCl (VWR, 27810.295). 100 µl of 2-heptanol (Sigma-Aldrich, H3003) (internal standard) solution in ethanol (Fisher Chemical, E/0650DF/C17) was added for a final concentration of 2.44 mg/L. Samples were flushed with nitrogen for 10 s, sealed with a silicone septum, stored at −80 °C and analyzed in batches of 20.

The GC was equipped with a DB-WAXetr column (length, 30 m; internal diameter, 0.32 mm; layer thickness, 0.50 µm; Agilent Technologies, Santa Clara, CA, USA) to the FID and an HP-5 column (length, 30 m; internal diameter, 0.25 mm; layer thickness, 0.25 µm; Agilent Technologies, Santa Clara, CA, USA) to the FPD. N 2 was used as the carrier gas. Samples were incubated for 20 min at 70 °C in the headspace autosampler (Flow rate, 35 cm/s; Injection volume, 1000 µL; Injection mode, split; Combi PAL autosampler, CTC analytics, Switzerland). The injector, FID and FPD temperatures were kept at 250 °C. The GC oven temperature was first held at 50 °C for 5 min and then allowed to rise to 80 °C at a rate of 5 °C/min, followed by a second ramp of 4 °C/min until 200 °C kept for 3 min and a final ramp of (4 °C/min) until 230 °C for 1 min. Results were analyzed with the GCSolution software version 2.4 (Shimadzu, Kyoto, Japan). The GC was calibrated with a 5% EtOH solution (VWR International) containing the volatiles under study (Supplementary Table  S7 ).

HS-SPME-GC-MS

HS-SPME-GC-MS (Shimadzu GCMS-QP-2010 Ultra) was used to measure additional volatile compounds, mainly comprising terpenoids and esters. Samples were analyzed by HS-SPME using a triphase DVB/Carboxen/PDMS 50/30 μm SPME fiber (Supelco Co., Bellefonte, PA, USA) followed by gas chromatography (Thermo Fisher Scientific Trace 1300 series, USA) coupled to a mass spectrometer (Thermo Fisher Scientific ISQ series MS) equipped with a TriPlus RSH autosampler. 5 ml of degassed beer sample was placed in 20 ml vials containing 1.75 g NaCl (VWR, 27810.295). 5 µl internal standard mix was added, containing 2-heptanol (1 g/L) (Sigma-Aldrich, H3003), 4-fluorobenzaldehyde (1 g/L) (Sigma-Aldrich, 128376), 2,3-hexanedione (1 g/L) (Sigma-Aldrich, 144169) and guaiacol (1 g/L) (Sigma-Aldrich, W253200) in ethanol (Fisher Chemical, E/0650DF/C17). Each sample was incubated at 60 °C in the autosampler oven with constant agitation. After 5 min equilibration, the SPME fiber was exposed to the sample headspace for 30 min. The compounds trapped on the fiber were thermally desorbed in the injection port of the chromatograph by heating the fiber for 15 min at 270 °C.

The GC-MS was equipped with a low polarity RXi-5Sil MS column (length, 20 m; internal diameter, 0.18 mm; layer thickness, 0.18 µm; Restek, Bellefonte, PA, USA). Injection was performed in splitless mode at 320 °C, a split flow of 9 ml/min, a purge flow of 5 ml/min and an open valve time of 3 min. To obtain a pulsed injection, a programmed gas flow was used whereby the helium gas flow was set at 2.7 mL/min for 0.1 min, followed by a decrease in flow of 20 ml/min to the normal 0.9 mL/min. The temperature was first held at 30 °C for 3 min and then allowed to rise to 80 °C at a rate of 7 °C/min, followed by a second ramp of 2 °C/min till 125 °C and a final ramp of 8 °C/min with a final temperature of 270 °C.

Mass acquisition range was 33 to 550 amu at a scan rate of 5 scans/s. Electron impact ionization energy was 70 eV. The interface and ion source were kept at 275 °C and 250 °C, respectively. A mix of linear n-alkanes (from C7 to C40, Supelco Co.) was injected into the GC-MS under identical conditions to serve as external retention index markers. Identification and quantification of the compounds were performed using an in-house developed R script as described in Goelen et al. and Reher et al. 87 , 88 (for package information, see Supplementary Table  S8 ). Briefly, chromatograms were analyzed using AMDIS (v2.71) 89 to separate overlapping peaks and obtain pure compound spectra. The NIST MS Search software (v2.0 g) in combination with the NIST2017, FFNSC3 and Adams4 libraries were used to manually identify the empirical spectra, taking into account the expected retention time. After background subtraction and correcting for retention time shifts between samples run on different days based on alkane ladders, compound elution profiles were extracted and integrated using a file with 284 target compounds of interest, which were either recovered in our identified AMDIS list of spectra or were known to occur in beer. Compound elution profiles were estimated for every peak in every chromatogram over a time-restricted window using weighted non-negative least square analysis after which peak areas were integrated 87 , 88 . Batch effect correction was performed by normalizing against the most stable internal standard compound, 4-fluorobenzaldehyde. Out of all 284 target compounds that were analyzed, 167 were visually judged to have reliable elution profiles and were used for final analysis.

Discrete photometric and enzymatic analysis

Discrete photometric and enzymatic analysis (Thermo Scientific TM Gallery TM Plus Beermaster Discrete Analyzer) was used to measure acetic acid, ammonia, beta-glucan, iso-alpha acids, color, sugars, glycerol, iron, pH, protein, and sulfite. 2 ml of sample volume was used for the analyses. Information regarding the reagents and standard solutions used for analyses and calibrations is included in Supplementary Table  S7 and Supplementary Table  S9 .

NIR analyses

NIR analysis (Anton Paar Alcolyzer Beer ME System) was used to measure ethanol. Measurements comprised 50 ml of sample, and a 10% EtOH solution was used for calibration.

Correlation calculations

Pairwise Spearman Rank correlations were calculated between all chemical properties.

Sensory dataset

Trained panel.

Our trained tasting panel consisted of volunteers who gave prior verbal informed consent. All compounds used for the validation experiment were of food-grade quality. The tasting sessions were approved by the Social and Societal Ethics Committee of the KU Leuven (G-2022-5677-R2(MAR)). All online reviewers agreed to the Terms and Conditions of the RateBeer website.

Sensory analysis was performed according to the American Society of Brewing Chemists (ASBC) Sensory Analysis Methods 90 . 30 volunteers were screened through a series of triangle tests. The sixteen most sensitive and consistent tasters were retained as taste panel members. The resulting panel was diverse in age [22–42, mean: 29], sex [56% male] and nationality [7 different countries]. The panel developed a consensus vocabulary to describe beer aroma, taste and mouthfeel. Panelists were trained to identify and score 50 different attributes, using a 7-point scale to rate attributes’ intensity. The scoring sheet is included as Supplementary Data  3 . Sensory assessments took place between 10–12 a.m. The beers were served in black-colored glasses. Per session, between 5 and 12 beers of the same style were tasted at 12 °C to 16 °C. Two reference beers were added to each set and indicated as ‘Reference 1 & 2’, allowing panel members to calibrate their ratings. Not all panelists were present at every tasting. Scores were scaled by standard deviation and mean-centered per taster. Values are represented as z-scores and clustered by Euclidean distance. Pairwise Spearman correlations were calculated between taste and aroma sensory attributes. Panel consistency was evaluated by repeating samples on different sessions and performing ANOVA to identify differences, using the ‘stats’ package (v4.2.2) in R (for package information, see Supplementary Table  S8 ).

Online reviews from a public database

The ‘scrapy’ package in Python (v3.6) (for package information, see Supplementary Table  S8 ). was used to collect 232,288 online reviews (mean=922, min=6, max=5343) from RateBeer, an online beer review database. Each review entry comprised 5 numerical scores (appearance, aroma, taste, palate and overall quality) and an optional review text. The total number of reviews per reviewer was collected separately. Numerical scores were scaled and centered per rater, and mean scores were calculated per beer.

For the review texts, the language was estimated using the packages ‘langdetect’ and ‘langid’ in Python. Reviews that were classified as English by both packages were kept. Reviewers with fewer than 100 entries overall were discarded. 181,025 reviews from >6000 reviewers from >40 countries remained. Text processing was done using the ‘nltk’ package in Python. Texts were corrected for slang and misspellings; proper nouns and rare words that are relevant to the beer context were specified and kept as-is (‘Chimay’,’Lambic’, etc.). A dictionary of semantically similar sensorial terms, for example ‘floral’ and ‘flower’, was created and collapsed together into one term. Words were stemmed and lemmatized to avoid identifying words such as ‘acid’ and ‘acidity’ as separate terms. Numbers and punctuation were removed.

Sentences from up to 50 randomly chosen reviews per beer were manually categorized according to the aspect of beer they describe (appearance, aroma, taste, palate, overall quality—not to be confused with the 5 numerical scores described above) or flagged as irrelevant if they contained no useful information. If a beer contained fewer than 50 reviews, all reviews were manually classified. This labeled data set was used to train a model that classified the rest of the sentences for all beers 91 . Sentences describing taste and aroma were extracted, and term frequency–inverse document frequency (TFIDF) was implemented to calculate enrichment scores for sensorial words per beer.

The sex of the tasting subject was not considered when building our sensory database. Instead, results from different panelists were averaged, both for our trained panel (56% male, 44% female) and the RateBeer reviews (70% male, 30% female for RateBeer as a whole).

Beer price collection and processing

Beer prices were collected from the following stores: Colruyt, Delhaize, Total Wine, BeerHawk, The Belgian Beer Shop, The Belgian Shop, and Beer of Belgium. Where applicable, prices were converted to Euros and normalized per liter. Spearman correlations were calculated between these prices and mean overall appreciation scores from RateBeer and the taste panel, respectively.

Pairwise Spearman Rank correlations were calculated between all sensory properties.

Machine learning models

Predictive modeling of sensory profiles from chemical data.

Regression models were constructed to predict (a) trained panel scores for beer flavors and quality from beer chemical profiles and (b) public reviews’ appreciation scores from beer chemical profiles. Z-scores were used to represent sensory attributes in both data sets. Chemical properties with log-normal distributions (Shapiro-Wilk test, p  <  0.05 ) were log-transformed. Missing chemical measurements (0.1% of all data) were replaced with mean values per attribute. Observations from 250 beers were randomly separated into a training set (70%, 175 beers) and a test set (30%, 75 beers), stratified per beer style. Chemical measurements (p = 231) were normalized based on the training set average and standard deviation. In total, three linear regression-based models: linear regression with first-order interaction terms (LR), lasso regression with first-order interaction terms (Lasso) and partial least squares regression (PLSR); five decision tree models, Adaboost regressor (ABR), Extra Trees (ET), Gradient Boosting regressor (GBR), Random Forest (RF) and XGBoost regressor (XGBR); one support vector machine model (SVR) and one artificial neural network model (ANN) were trained. The models were implemented using the ‘scikit-learn’ package (v1.2.2) and ‘xgboost’ package (v1.7.3) in Python (v3.9.16). Models were trained, and hyperparameters optimized, using five-fold cross-validated grid search with the coefficient of determination (R 2 ) as the evaluation metric. The ANN (scikit-learn’s MLPRegressor) was optimized using Bayesian Tree-Structured Parzen Estimator optimization with the ‘Optuna’ Python package (v3.2.0). Individual models were trained per attribute, and a multi-output model was trained on all attributes simultaneously.

Model dissection

GBR was found to outperform other methods, resulting in models with the highest average R 2 values in both trained panel and public review data sets. Impurity-based rankings of the most important predictors for each predicted sensorial trait were obtained using the ‘scikit-learn’ package. To observe the relationships between these chemical properties and their predicted targets, partial dependence plots (PDP) were constructed for the six most important predictors of consumer appreciation 74 , 75 .

The ‘SHAP’ package in Python (v0.41.0) was implemented to provide an alternative ranking of predictor importance and to visualize the predictors’ effects as a function of their concentration 68 .

Validation of causal chemical properties

To validate the effects of the most important model features on predicted sensory attributes, beers were spiked with the chemical compounds identified by the models and descriptive sensory analyses were carried out according to the American Society of Brewing Chemists (ASBC) protocol 90 .

Compound spiking was done 30 min before tasting. Compounds were spiked into fresh beer bottles, that were immediately resealed and inverted three times. Fresh bottles of beer were opened for the same duration, resealed, and inverted thrice, to serve as controls. Pairs of spiked samples and controls were served simultaneously, chilled and in dark glasses as outlined in the Trained panel section above. Tasters were instructed to select the glass with the higher flavor intensity for each attribute (directional difference test 92 ) and to select the glass they prefer.

The final concentration after spiking was equal to the within-style average, after normalizing by ethanol concentration. This was done to ensure balanced flavor profiles in the final spiked beer. The same methods were applied to improve a non-alcoholic beer. Compounds were the following: ethyl acetate (Merck KGaA, W241415), ethyl hexanoate (Merck KGaA, W243906), isoamyl acetate (Merck KGaA, W205508), phenethyl acetate (Merck KGaA, W285706), ethanol (96%, Colruyt), glycerol (Merck KGaA, W252506), lactic acid (Merck KGaA, 261106).

Significant differences in preference or perceived intensity were determined by performing the two-sided binomial test on each attribute.
