The following is and excerpt from the Specialty Coffee Association in regard to the Coffee Taster's Flavor Wheel.   

Originally published in 1995, the Coffee Taster's Flavor Wheel—one of the most iconic resources in the coffee industry—has been the industry standard for over two decades. In 2016, this valuable resource was updated in collaboration with World Coffee Research (WCR).

The foundation of this work, the World Coffee Research Sensory Lexicon, is the product of dozens of professional sensory panelists, scientists, coffee buyers, and roasting companies collaborating via WCR and SCA. This is the largest and most collaborative piece of research on coffee flavor ever completed, inspiring a new set of vocabulary for industry professionals.
