Anatomy of the wheel
Three rings, one vocabulary

Ring 1 (center) names broad families β Fruity, Floral, Sweet, Nutty/Cocoa, Spicy, Roasted, Sour/Fermented, Green/Vegetative, Other. Ring 2 splits each family into groups (Fruity β Berry, Citrus, Stone, Tropical). Ring 3 names specific descriptors (Berry β Blueberry, Strawberry, Raspberry, Blackberry). Colors echo the sensation β red for ripe fruit, pink for floral, brown for roast.
CRAFT NOTE
The wheel was published by the SCA & World Coffee Research in 2016, built from a sensory lexicon of 110 attributes. Every word was tested with reference samples β 'blueberry' means the same thing in Oslo and Addis Ababa.
