SCA Golden Cup Technician - Probat Lab (more photos)
Attended the Specialty Coffee Assignation’s Golden Cup Technician Educational Pathway at the Probat Lab outside of Chicago. This was is the third class offered by Firedancer Coffee Consultants that I have taken now and it was just as well taught as the roasting and green coffee buying classes.
In our lab time we brewed on the Chemex, Hario V60, and in the French Press. We practiced tasting the coffee brewed on spec, as well as with adjustments made to the grind, quantity of ground coffee, temperature, and time of contact with between the water and ground coffee. Each of these adjustments through the flavor profile off, which helped us develop discernment between coffee brewed on spec and coffee brewed incorrectly.
We also used a TDS Meter to measure the total dissolved solids in the coffee to see where the extraction fell on the SCA Golden Cup chart. After this we practiced adjusting the brewing profile to move it to different points on the chart. Although part of the Coffee Roasting class, while cupping, we also practiced disinterment in tasting defects in the water that will effect the flavor of the coffee.
Suggestions for Changing the Curriculum
While I did find the the hands on use of the brewing devices, learning to taste brewing defects, using the TDS Meter with the Golden Cup chat, and tasting the water defects useful there were a number of things that could have been added.
- Including information on the green coffee type, date of harvest, storage information, roast profile, Agtron number, and days off harvest. All of this information adds to the depth of understanding the final flavor profile produced by the brew.
- Including more details of the brewing profile including as the grind size, grind weight, water quality, water start and end temp, pour profile chart, pour technique used, water flow rate, retention of water in the grounds, and challenging information. As each of these elements of the brew can greatly effect the final extraction, it is useful to record it.
- Including full tasting of the coffee using the SCA Cupping form, with the addition of areas to record the paper taste or sediment. Doing sampling brewing taste tests between (1) three different coffees using the same brewing device and (2) the same coffee brewed in three different devices would help students better discern the effect the brewing devices is having on the flavor profile. Going through this process help us move past choosing the brewing device that we like best and towards choosing the one that helps the natural characteristics of the coffee best shine.
When we start collecting the pre-brewing data of the coffee, more detailed brewing profile data, and advanced tasting profile data we are able to better adjust the elements to improve the final quality of the coffee. Over time, using this data can help us improve our best practices for brewing Coffeehouse and drawing the best flavors out of the been. Without doing such things I feel like we do Brewbar flying blind or in a Willy Nilly fashion. Our costumers deserve better, not to mention the coffee farmers and roasters who put a lot of hard work into proving us with great coffee to work with.
My hope is that in time, the SCA and coffee industry as a whole will start taking manual coffee brewing as seriously as they do roasting, batch, cupping, batch brewing, and espresso extraction.
