Green coffee descriptors wheel
Exploring flavors and aromas in sensory evaluation
Sensory evaluation tool
The descriptor wheel is a fundamental tool for the person who is going to evaluate a coffee through sensory evaluation or cupping, whether professional or for those people who are just starting out in the world of coffee. It is during this practice that the cupper, by means of tasting and smell, determines and values each of the characteristics that define a coffee.
The cupper is capable of identifying unique characteristics and descriptors in coffee, but sometimes these olfactory sensations are complex and difficult to catalog, therefore the objective of the descriptor wheel is to serve as an aid, a complement and a tool that supports the sensory memory in the description of a coffee.
Explore the sensory nuances and enrich your coffee experience.
What is the reading process?
For a correct reading of the descriptor wheel, it must be read from the center to the outside. Starting with the three basic groups of olfactory and taste sensations: enzymatic, caramelization and dry distillation, the 145 most common descriptors usually found in coffee have been compiled:
Enzymatic: those compounds that are mainly the result of enzymatic reactions that the grain has undergone while it was still a living organism, such as herbal, floral or fruity aromas. In this group we can highlight the most perfumed aromas.
Caramelization: they are the result of the caramelization of sugars that occurs during the roasting process, here we find chocolates, caramels and sugars.
Dry distillation: They result from higher roasting processes, although they are also characteristic of certain origins.
If one moves from the first circle, corresponding to the center of the wheel, to the back circle through each of the 3 more general groups, the precision of the sensations is increased, differentiating up to 9 subgroups.
The enzymatic group is divided into fruity, fragrances, alcohols, fermented and vegetable; the dry distillation group is divided into spices, and the caramelization group is subdivided into sweets, nuts and chocolates.
