Lab Card

Flavor Wheel
The image below is a reproduction of a card we make available to customers. It's a useful tool for continuing to learn roasting skills and awareness. The Flavor Wheel is the official flavor chart developed by the Specialty Coffee Association and World Coffee Research. It visually illustrates the various flavors (and aromas) typically found in coffee, along with their relationship to one another.
Roast Color Guide
The roast color chart offers a simplified nomenclature for degrees of roast (darkness), avoiding the often used but often seemingly arbitrary terms like "full city,"etc. The numeric values are approximations of Agtron spectrometer numbers, the coffee industry's most relied upon scale to accurately measure roast degrees. Again, these colors are only approximations. For accuracy, Agtron color cards are available from Agtron, as are their laboratory spectrometers.
