Licensed Q Robusta Graders must calibrate with each other every three years in order to test their abilities to accurately evaluate coffee quality based on their gained experience, knowledge, and standards/protocols learned in Q training. It is mandatory for all Q Graders to participate in a calibration if they wish to remain active as a Q Grader in good standing.
The calibration consists of three cupping flights, (or tables- 6 samples each) of coffees with distinct attributes. All Q Graders must be in calibration and pass two of the three flights in order to renew their licenses and continue as Licensed Q Graders. Upon passing, the Q Grader license will remain valid for another 36 months, starting from the day of the calibration course.
During the course, students will also participate in the new Flavor Calibration which will not be graded but counted as practice only.
