Certified Q Arabica 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 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. The sessions include one of Washed Milds, one of Naturals and one of either Africa or Asia. All Q Graders must be in calibration and pass two of the three flights in order to renew their certifications and continue as Certified Q Graders. Upon passing, the Q Grader certification will remain valid for another 36 months, starting from the day of the calibration course.

This course will also feature the new flavoractiv calibration. A set of 6 flavors must be identified from a choice of 14 possible flavors.
