The Scientific Basis For The Coffee Flavor Wheel

In 2016, SCAA updated and compiled the vocabulary of coffee flavor description, helping people to transform their subjective feelings about coffee into objective and acceptable descriptions.

Emma Sage, SCA’s Coffee science Manager, and Hanna Neuschwander, World Coffee Institute, take an in-depth look at the science behind the new flavor wheel in SCA’s 2016 chronicle. The ultimate goal of the project is to understand the overall quality of coffee in a very different way than cup testing. This is quantifiable and will not make much of a difference even to most cupologists who have had their taste corrected.

Despite intensive cupping training, the sensory experts actually tasted more flavor than the certified cuppers in the first round of tests. After tasting 13 Colombian coffees, the cup testers used 59 words to describe flavor, while the sensory experts agreed 100 percent on 92 words. This proves that no matter how rigorous the cupping process is, it cannot trump the aid of science.

In the absence of caffeine, symptoms such as headache, drowsiness, decreased concentration, and nausea can occur if you are already dependent. Don’t take caffeine dependence lightly, it can have an adverse effect on your health. Using a caffeine calculator - https://roastercoffees.com/caffeine-calculator/ can help you control your caffeine intake to avoid these adverse effects.

In order to start the experiment, we did some basic preparation work. At Kansas State University, five sensory scientists spent 150 hours analyzing 105 coffee samples from 14 countries. To avoid the distraction of unintelligible cupped flavor descriptions, these flavors are paired to specific flavor perceptions.

For example, instead of being described as a berry that grows on a mountain wall in Argentina and served as an appetizer at a lavish dinner, blackberries would be described as Smuckers -- blackberry jam. These specific reference words allow the cup tester to measure and quantify the strength of each flavor. After identifying 99 words, another team of sensory scientists confirmed them.

To find words that fit the 99 flavor descriptions on the flavor wheel, SCAA and the University of California, Davis, gathered sensory scientists and coffee industry experts to connect the dots. The results divided the words into nine categories within the flavor wheel (sweet, floral, fruity, etc...).

While there may seem to be a lot of science involved in describing coffee flavors, that doesn’t kill the baked beans. Compiling flavor words is just the first step. The goal is to be able to describe flavors in the same language, through deeper research into coffee varieties, and to understand what makes them good. These words are the beginning of an experiment to find out whether certain chemicals in coffee reflect certain flavors or are the result of factors more influenced by the environment.

Once the nature problem is solved, the nurture problem can be solved, which means that the scientific way can be taken to the farming stage to show farmers that they can highlight certain flavors and open up new ways of growing. Perhaps soon baked bean makers will be able to roast coffee varieties with aromas as subtle as a ’72 Mustang cushion leather.

You may have come into contact with the coffee flavor wheel, which is a tool diagram designed by the American Fine Coffee Association in order to provide guidelines and basis for coffee flavor correction. The importance of the flavor wheel is to unify the language that different people use to describe the taste of coffee. This consistency and the results of the research on the taste sense helps the practitioners to communicate about the taste of coffee.
