The original brewing control chart is overlaid with acceptability zones describing cup flavors. However, these terminologies (strong, bitter, weak, over, and under-developed) are outdated and their definitions are not standardized in the industry. In this lecture, the newest results from the UC Davis Coffee Center will be presented, which used the WCR Sensory Lexicon in order to elucidate new flavor attributes related to coffees of different strengths and extractions. The experiment evaluated a single origin coffee roasted to three different development times in order to assess the importance of roast on the flavor at different strengths and extractions. The position of the coffees on the brewing control chart was modified by using a programmable batch brewer. A descriptive analysis panel was used to capture the sensory profile of these coffees. The results presented will be used to update the descriptive zones of the new brewing control chart.
In today’s lecture by Dr. Scott Frost, you’ll learn all about how flavor can be modified through the brewing process, and how the control chart can be used to create different flavors for a specific coffee.
Scott received his Master of Science in Viticulture and Enology and Ph.D. in Agricultural and Environmental Chemistry from the University of California, Davis. His graduate research focused on evaluating the sensory and chemical changes in wine as a result of specific enological practices. At the time of the recording, Scott worked at the UC Davis Coffee Center as a Postdoctoral Scholar. His project applies quantitative sensory methods to capture the sensory profile of brewed coffee.
