Structure and function

The SCA Coffee Taster’s Flavor Wheel was first published in 1995 and fundamentally revised in 2016 in collaboration with World Coffee Research. It is the most widely used tool in sensory coffee analysis.

The circle works like a map: in the center are broad categories — fruity, floral, sweet, nutty, spicy, chocolatey, roasted, vegetative. The further you go outward, the more specific the description becomes. “Fruity” becomes “berry”, then “blueberry” or “blackberry”. This is how you learn to translate vague impressions (“tastes somewhat like fruit”) into precise terms.

The colors and distances between the segments are deliberately chosen: closely spaced aromas are sensorially related, widely separated ones are clearly distinguishable. This helps during cupping — if you perceive “stone fruit,” you look in the neighboring segment to see if it’s more peach or apricot.

How to use it

You don’t need to memorize the Flavor Wheel. Hang it in the kitchen or look at it while drinking coffee. If you can’t name a taste, go from the inside out: is it more sweet or sour? Fruity or nutty? Which fruit? After a few weeks, you’ll have a vocabulary that goes beyond “strong” and “mild.”

In practice at Green Wall Coffee

At Sophienstraße 27 in Berlin-Lichtenberg, we don’t actually have a giant Flavor Wheel hanging on the wall, but we apply the principles behind it every day. When guests ask, “What does this taste like?”, we try to find the fitting terms together. This makes coffee more concrete and the conversation about taste easier — without it becoming academic.
