What Is a Q Grader? The Coffee Tasters Behind SCA Scores

Behind every SCA score on a specialty bag is a trained taster. Here is who they are and what they do.

The Short Answer

Bottom line
A Q Grader is a coffee taster licensed through the Coffee Quality Institute to score coffee on the 100-point SCA scale. 38 of the 619 coffees in our index (6%) publish a score, from 11 roasters.

How Q Graders Are Certified

Candidates attend a multi-day course and sit a series of exams on sensory skill and green coffee knowledge. Passing earns a license, and it has to be renewed by recertifying, so scores stay calibrated between tasters.

That shared calibration is the point: a 88 from one Q Grader should mean roughly the same as an 88 from another. See the full scale in What Is a Good Coffee Cupping Score?

What a Q Grader Scores

AttributeWhat it covers
Fragrance and aromaThe smell of the dry grounds and the wet coffee after water is added.
Flavor and aftertasteThe main taste impression, and what lingers after you swallow.
Acidity and bodyBrightness on the palate, and the weight or texture of the liquid.
Balance and sweetnessHow the parts fit together, and how much natural sweetness shows.
Uniformity and clean cupConsistency across cups, and freedom from off-tastes.
Overall and defectsThe taster’s final impression, with points removed for flaws.

They rate attributes like fragrance and aroma, flavor, aftertaste, acidity, body, balance, sweetness and overall impression, then subtract points for defects, to reach a score out of 100.
Is a Q Grader score the same as a rating?
