What Is a Q Grader? How Coffee Is Professionally Scored
Share
When a coffee bag says “86 points,” somebody had to taste it and put a number on it. Very often that person is a Q Grader. So what is a Q grader? It is a coffee taster who has passed a demanding certification in sensory skills and green coffee grading, and who scores coffees using a shared, standardized protocol. The point of the system is a common language: a Q Grader in Colombia and one in Kenya should give the same coffee a similar score, so buyers and farmers can trade on quality, not just volume.
Here is how the scoring works, what the exam involves, how the program changed in 2025 and what those scores mean for the coffee in your cup.
Key takeaways
- Q Graders are certified cuppers trained to evaluate coffee consistently against a written protocol.
- Coffees scoring 80 points or more out of 100 under the traditional cupping form, with very few defects, are generally classed as specialty.
- The certification was created by the Coffee Quality Institute (CQI). In 2025, the Specialty Coffee Association (SCA) announced it was taking over the program.
- A score describes quality under test conditions, not personal taste. A lower-scoring coffee can still be the one you like best.

What is a Q grader and what do they actually do?
A Q Grader works at the point where green coffee changes hands. Typical employers are importers, exporters, cooperatives, roasters and quality labs. Their day-to-day work includes:
- Grading green coffee: counting and classifying physical defects in a sample of unroasted beans (insect damage, black or sour beans, broken beans, stones and sticks).
- Cupping: roasting a sample lightly, brewing it in a standard way and tasting it methodically.
- Scoring and describing: filling in a standardized form and writing tasting notes that buyers can rely on.
- Calibrating: cupping alongside other graders so their scores stay consistent with the group.
The letter Q simply stands for quality. The idea is similar to wine certification, but with one key difference: Q grading is designed for trade, especially to help producers prove that a lot deserves a better price.
How coffee is scored
Under the long-used SCA cupping protocol, which Q Graders were trained on, a coffee is roasted to a light, standard level, ground, and steeped in cups with hot water. After a few minutes the cupper breaks the crust of grounds, smells the aroma, skims, and tastes with a loud slurp as the coffee cools.
The form scores a list of attributes, each on a scale with fine increments, then adds them up:
- Fragrance and aroma
- Flavor and aftertaste
- Acidity and body
- Balance and overall impression
- Uniformity, clean cup and sweetness, checked across several cups of the same sample
Defects found in the cup reduce the total. Tasting at several temperatures is part of the method, because a coffee can taste very different as it cools. Our guide to coffee cupping shows how to try the process at home.
The green grading part
Physical grading matters as much as taste. Under SCA green grading standards, a sample of 350 g of green coffee is inspected. To be graded specialty, it must have zero primary (category 1) defects and no more than five full defects in total, along with other moisture and uniformity requirements. A delicious cup with too many defective beans still fails. For how countries grade beans by size and altitude, see our guide to coffee grades.
What the numbers mean
| Score (100-point scale) | Common description | Where you usually find it |
|---|---|---|
| 90 and above | Outstanding | Competition lots, rare micro-lots, auction coffees |
| 85–89.99 | Excellent | High-end single origins |
| 80–84.99 | Very good | Most specialty coffee and quality blends |
| Below 80 | Below specialty grade | Commercial and supermarket coffee |
Two things to keep in mind. First, scores are assessed on lightly roasted samples, not on the roast you drink. Second, the scale is not linear in price: a coffee at 88 can cost several times one at 84. If you want to know what “specialty” means beyond the number, read what is specialty coffee.
The Q Grader exam
Getting certified has traditionally meant an intensive course of about a week, ending in a series of roughly twenty tests. Candidates typically had to pass areas like these:
| Test area | What it checks |
|---|---|
| Olfactory | Identifying aromas from a reference kit by smell alone |
| Triangulation | Spotting the odd cup out among three, repeatedly |
| Sensory skills | Detecting and ranking sweet, sour and salty solutions at different strengths |
| Organic acids | Telling apart acids such as citric, malic, acetic and phosphoric in coffee |
| Cupping calibration | Scoring coffees close to the expert reference scores |
| Green grading | Identifying and counting defects in green coffee |
| Roast identification | Recognizing roast-related defects and sample roast quality |
Many candidates did not pass every section on the first attempt and returned for retakes. Certified graders also had to recalibrate periodically, traditionally every three years, to keep their license.
What changed in 2025
In April 2025, Daily Coffee News reported that the Specialty Coffee Association was taking over the Q Grader program from the Coffee Quality Institute. The SCA now presents an updated Q Grader course on its education site, aligned with its newer Coffee Value Assessment, which separates descriptive tasting, affective (liking) scores and physical grading more clearly than the older single-form system.
Course formats, test lists and fees are evolving, so if you are thinking of becoming a Q Grader, check the SCA’s current requirements rather than older guides. For trade purposes, the long-used 80-point threshold for specialty coffee remains the familiar reference in most of the industry.
What this means when you buy coffee
- A score is a starting point, not a verdict. It tells you a coffee is clean and well made. Whether you love bright citrus or deep chocolate is up to you.
- Tasting notes are more useful than numbers. Notes written in the cupper’s shared vocabulary tell you what to expect.
- Freshness changes everything. An 87-point coffee that is three months past roast can taste worse than a fresh 83.
To explore how professionals describe origin character, try coffees with very different profiles side by side: our Kenya Nyeri (washed, SL28 and SL34 varieties, orange, lemon and floral notes), the Ethiopia Natural from Sidama (heirloom varieties, ripe fruit, milk chocolate and caramel) and Guatemala Antigua (dark chocolate, bright fruit, butterscotch). Cupping them together is the best way to understand what graders listen for.
Q Grader FAQ
How long does it take to become a Q Grader?
The course itself has traditionally taken about a week, but most successful candidates spend months or years cupping beforehand.
Is there a Q Grader for Robusta?
Yes. A separate Robusta track (often called R Grader) has existed alongside the Arabica program.
Do Q Graders work in coffee shops?
Some do, but most work in buying, quality control and roasting, where scores influence purchase decisions.
Can a coffee scoring under 80 taste good?
Yes. Many enjoyable everyday coffees and dark-roast blends sit below 80. The score measures quality under a protocol, not enjoyment.
