The Q Robusta program (formerly R Grader) creates a skilled and credible body of Robusta coffee cuppers. The Coffee Quality Institute started this program with the goal of cuppers accurately and consistently assessing Robusta coffee cup quality. The Q Robusta program is the only recognized certification system for Fine Robusta coffee cuppers today. It’s the same as its Q Arabica counterpart, with slightly varied exams (general knowledge, matching pairs of acids, olfactory scents, and coffees).

R Graders are Robusta cuppers recognized as skilled to:

  • Objectively assess coffee quality
  • Identify, quantify, and articulate coffee characteristics
  • Detect coffee defects
  • Communicate coffee characteristics using standard industry terminology

After completing the Q Robusta (R Grader) program, certified Q Robusta Graders may grade coffees for CQI or an in-country partner. A Q Robusta Grader certificate is valid for three (3) years and is renewable upon completion of an accredited calibration.

A Q Robusta Course is a five (5) day exam consisting of twenty-two (22) individual tests that must be passed to qualify for certification. Candidates failing any sections may retake those tests anytime within eighteen (18) months.

Note: Presently licensed Q Arabica Graders must take all Q Robusta Grader exams to qualify as Q Robusta Graders.
