The Coffee Taster's Flavor Wheel is the vocabulary the coffee trade uses to describe taste. This article explains what it is, where it came from, how to use it, and — importantly for anyone thinking of reproducing it — what its licence actually permits.

The wheel above is this encyclopedia's own simplified version. It is not the Specialty Coffee Association flavour wheel and does not reproduce it.

What the Wheel Is

A flavour wheel is a vocabulary tool, not an answer key. It does not tell you what is in the cup. It gives you a structured way to name what you are already tasting.

You start at the centre with broad categories and work outward to increasingly specific ones. A coffee that reads as "fruity" at the hub becomes "berry" one ring out and "blueberry" at the rim. You can stop anywhere. The further out you go, the more precise the description — and the more easily you can be wrong.

The critical point, and the one most often missed: it is descriptive, not evaluative. It lets you say a coffee tastes of molasses. It says nothing about whether that is good.

1995, and the 2016 Rebuild

The original Coffee Taster's Flavor Wheel was published in 1995 by the Specialty Coffee Association of America, and it was the industry standard for more than two decades.

In 2016 it was rebuilt from the ground up, in a collaboration between the Specialty Coffee Association — by then formed from the merger of the SCAA with its European counterpart — and World Coffee Research.

The rebuild was not a redesign of the graphic. It was a reconstruction of the vocabulary underneath it, and the method is worth stating because it is unusually rigorous for a tasting reference. Seventy-two experts sorted the lexicon's flavour attributes in a structured exercise without tasting anything, and the resulting data were clustered statistically to determine which flavours belong near which. The arrangement of the modern wheel is the output of that analysis rather than of an editor's judgement.

The Sensory Lexicon

Underneath the wheel sits the World Coffee Research Sensory Lexicon, developed by sensory scientists at Kansas State University with coffee professionals from thirteen countries. Its first edition contains 110 attributes. A second edition, published in 2017, added references for a further 24.

Three properties make it different from an ordinary list of tasting words.

It is descriptive. It records what a coffee smells and tastes of. It makes no quality judgement.

It is quantifiable. Every attribute carries an intensity score on a scale of 1 to 15, so two coffees can be compared by degree rather than by adjective.

It is replicable. Every reference is tied to a specific, repeatable physical food sample rather than to a word. Used properly, an evaluator in one country and an evaluator in another arrive at the same number for the same attribute.

That last property is what turns a vocabulary into a measurement, and it is why the lexicon matters more than the poster.

The Nine Categories

The wheel's outer structure resolves into nine broad flavour categories, each branching into progressively more specific descriptors. A reader working with it moves from the general to the particular, stopping at whatever level they can honestly defend.

Acidity, Body and Mouthfeel

The wheel covers flavour and aroma. Two other dimensions of a cup are described separately.

Acidity is not sourness. It is the brightness that makes a coffee taste lively rather than flat, and tasters describe its character — citric, malic, tartaric, phosphoric — as well as its intensity.

Body, or mouthfeel, is the physical sensation: how heavy the liquid feels, whether it coats the mouth, whether it finishes clean or lingers.

The two are independent. A coffee can be bright and thin, or soft and heavy, or any combination. Describing them separately is more useful than collapsing them into "smooth".

Origins Do Not Have Flavour Profiles

This encyclopedia previously published a section here called Common Descriptors by Origin, giving eight coffee origins a fixed flavour profile each, in the encyclopedia's own voice, with no source. Puerto Rico was among them, and a second passage attributed nutty and cocoa descriptors to Latin American coffees generally, naming Brazil, Colombia and Puerto Rico.

All of it has been removed, and this page is the reason the removal matters most.

An origin is not a flavour. A country contains thousands of farms at different altitudes, growing different varieties, processed differently, roasted differently, and picked in different years. The range within any one origin is wider than the average difference between origins.

Worse, on this page of all pages, the claim contradicts the tool the article exists to explain. The wheel is a device for describing the coffee in front of you. An origin profile is a device for deciding in advance what you are going to taste, which is the opposite thing — and a taster who knows what a coffee is supposed to taste like will find it.

If a description is worth publishing, it names the lot, the assessor and the protocol. Without those three it is not a description, it is an expectation.

What the Licence Permits

This matters to anyone reproducing the wheel, and this encyclopedia previously got it wrong.

Each of those three terms is a real restriction:

Attribution — the SCA and WCR must be credited.
NonCommercial — it may not be used for commercial purposes. A site carrying advertising or selling a product is commercial use.
NoDerivatives — it may not be altered, cropped, redrawn or adapted.

The SCA also distributes its digital file password-protected, states that it may not be printed larger than the size supplied, and describes it as intended for personal digital use.

This encyclopedia previously described the wheel as "free online through SCA and WCR". It can be obtained without payment, which is not the same as being free to reuse, and the earlier wording invited exactly the misunderstanding this section now closes. That is why the wheel at the top of this page is this encyclopedia's own simplified version rather than the SCA's.

A portion of the proceeds from every SCA flavour wheel poster and digital file sold supports World Coffee Research.

Key Facts

The Coffee Taster's Flavor Wheel was first published in 1995 by the SCAA.
It was rebuilt in 2016 by the SCA with World Coffee Research.
It rests on the WCR Sensory Lexicon: 110 attributes in its first edition, plus 24 more in the 2017 second edition.
The lexicon was developed at Kansas State University with professionals from thirteen countries.
Attributes carry intensity scores from 1 to 15, each tied to a repeatable physical reference.
Seventy-two experts sorted the attributes to determine the wheel's arrangement.
The wheel is descriptive, not evaluative.
Licence: CC BY-NC-ND 4.0. Attribution required, no commercial use, no derivatives.
The wheel on this page is this encyclopedia's own simplified version, not the SCA wheel.

Frequently Asked Questions

Is the wheel on this page the SCA flavour wheel? No. It is this encyclopedia's own simplified version and it does not reproduce the SCA wheel.

Can I use the SCA flavour wheel on my website? Not if your site is commercial, and not in altered form. It is licensed CC BY-NC-ND 4.0 — attribution required, non-commercial use only, no derivatives. Check the licence terms against your own use.

Does the wheel tell me if a coffee is good? No. It is descriptive. It records what a coffee tastes of and makes no quality judgement.

What is the Sensory Lexicon? The research underneath the wheel: 110 attributes in its first edition, each with an intensity scale from 1 to 15 and a repeatable physical reference sample.

Does Puerto Rican coffee have a typical flavour profile? No, and neither does any other origin. This encyclopedia previously published profiles for eight origins on this page and has removed all of them.

Where do I start when tasting? At the centre of the wheel, and work outward only as far as you can honestly defend.

Claims this encyclopedia could not source

Fixed flavour profiles for eight named coffee origins, including Puerto Rico, previously published on this page in the encyclopedia's own voice. No sensory data across any origin was located, and the claim contradicts the descriptive purpose of the wheel itself.
That nutty and cocoa descriptors are characteristic of Latin American coffees generally. The same shape, applied to a region.
That the SCA flavour wheel is "free online". It can be obtained without payment; it is licensed CC BY-NC-ND 4.0 and is not free to reuse.
That the wheel is used in Q Grader certification training. Plausible and widely stated; no citation located.
The acidity, body and palate-training guidance in this article. Sound and standard, but not traced to a published source.
