Cupping is the standardised method the coffee trade uses to taste and score coffee. This article sets out the protocol, the scoring system, what replaced it, and what a score does and does not tell you — with the source named for each figure, and with the claims this encyclopedia could not trace stated plainly at the end.

What Cupping Is

Cupping exists so that two people in different countries tasting the same coffee arrive at comparable conclusions. Everything about it — the dose, the water, the temperature, the timing, the number of cups — is fixed so that the coffee is the only variable.

Coffee is ground, hot water is poured directly onto the grounds, a crust forms, the crust is broken and the aroma assessed, and the liquid is then tasted by slurping from a spoon. Slurping aerates the coffee across the whole palate; it is technique, not theatre.

The Protocol

These are the parameters of the Specialty Coffee Association's 2004 Cupping Protocol and Form:

Parameter	Specification
Coffee dose	8.25 g per cup
Water	150 ml per cup, a ratio of about 1:18
Water temperature	93 °C (200 °F)
Cups per sample	5
Crust break	at 4 minutes

Five cups per sample is the part outsiders miss. It is not generosity — it is how the taster detects a defect present in one bean out of a batch. A taint in one cup of five tells you something a single cup cannot.

The 100-Point Form, and What Replaced It

The 2004 form scored ten attributes out of ten, for a total out of 100: fragrance and aroma, flavour, aftertaste, acidity, body, balance, uniformity, clean cup, sweetness and overall.

That form is no longer the SCA's standard, and this encyclopedia previously described it as current. The SCA has adopted the Coffee Value Assessment, whose components — SCA Standard 102, Sample Preparation and Cupping Mechanics; SCA Standard 103, Descriptive Assessment; and SCA Standard 104, Affective Assessment — supersede the 2004 Cupping Protocol and Form.

Dates differ between sources and both are given. The Coffee Value Assessment was released in beta at the Specialty Coffee Expo in Portland in April 2023, and its standards carry 2024 numbering. Industry reporting placed adoption of the descriptive and affective components in November 2024; the SCA's own announcement of adoption is dated to 2025.

The Coffee Value Assessment works across four dimensions rather than one number:

Physical — green coffee: moisture, appearance, visible damage.
Extrinsic — identity, certification, origin.
Descriptive — what the coffee tastes like, rated for intensity rather than quality.
Affective — how desirable those attributes are, rated 0 to 9 across eight categories.

The affective form caps at 72 points, not 100, which is why the SCA published a calculator to translate scores onto the older scale. The stated reason for the change is that a single number was never an adequate description of a coffee's value.

The 2004 form remains in wide use as industry custom during the transition. An article describing it is not wrong; an article describing it as the current standard is.

The 80-Point Line

Under the 2004 protocol, specialty grade required two things, and most writing about it mentions only the first.

A cupping score of 80 or above.
A physical grade: zero primary defects and no more than five secondary defects in a green sample, and no quakers in a roasted sample. Published sources give the green sample size as 350 grams, and some give 300.

This encyclopedia previously gave the 80-point line without the physical grade, and it also gave a band labelled "75–79 (Premium)". There is no SCA band called Premium. The legacy form names no tier below specialty. That label has been removed.

Scores and Prices

This encyclopedia previously stated that each point above 85 roughly doubles wholesale price, and in the next breath that a 90-point coffee sells for four to eight times an 80-point coffee. Those two statements cannot both be true: doubling for each of five points is a factor of thirty-two, not four to eight. Neither figure carried a source. Both have been removed.

What can be said without inventing a multiplier is the shape of it. Score correlates with price, the relationship is steeper at the top of the scale than the bottom, and the commercial practice many roasters now follow is to buy at 84 points and above while 80 to 83 remains specialty grade. That is a purchasing convention, not a change in the rule.

Q Graders

Placeholder graphic. No photograph is available for this section.

A Q Grader is a cupper licensed by the Coffee Quality Institute to evaluate arabica coffee using the SCA system. The programme was launched by CQI in 2004.

Certification is a six-day course ending in a series of examinations across sensory skills, cupping skills, green and roast grading, organic acid identification, triangulation and general coffee knowledge. CQI's own current course description gives 20 examinations. This encyclopedia previously gave 22, which is widely repeated; the figure is reported here as CQI states it, and the discrepancy is recorded at the end.

On renewal, this encyclopedia previously said Q Graders must retake certification every three years. That compresses two different requirements, and CQI's guidebook separates them:

The certificate is valid for 36 months.
Renewal is by attending and passing a Q Calibration Course — three cupping flights of six samples each, one Washed Milds, one Naturals, and one of either Africa or Asia. A grader must pass at least two of the three flights.
The window to calibrate opens six months before expiry and closes six months after it.
The 18-month figure that circulates is something else entirely: it is the time allowed to complete all written and practical examinations from the original course enrolment date.

So it is recalibration every three years, not a retake of the whole certification.

On how many exist, sources differ. This encyclopedia previously gave roughly 10,000 as of the mid-2020s with no citation; trade reporting in 2023 gave more than 7,000. No authoritative current count was located and neither figure is asserted here.

Cupping Puerto Rican Coffee

Puerto Rican coffee is cupped by the same protocol as any other origin. There is nothing distinctive about the method when the coffee is Puerto Rican.

Three claims previously on this page have been removed, and the removals matter more than what replaced them.

"Authentic Puerto Rican coffee from quality producers consistently scores in the 82–88 range." No cupping records supporting this were located. The same claim, in a narrower band, was removed from two other articles in this encyclopedia earlier this month. This page carried the last surviving instance of it.

"Puerto Rican cupping notes typically include chocolate, caramel, nuts, balanced acidity and medium body." A sensory generalisation across an entire origin, with no cupping data behind it. Origins do not have flavour profiles; lots do.

"Puerto Rican coffees increasingly appear in international competitions, with some achieving notable scores." No competition, year, producer or score was named, and none could be located. For the record, the Cup of Excellence programme has never been held in Puerto Rico.

What can honestly be said is narrower and more useful: a score is meaningful only when the assessor and the protocol are named. A number with neither attached is not a measurement.

Key Facts

Cupping standardises dose, water, temperature and timing so the coffee is the only variable.
2004 SCA protocol: 8.25 g per cup, 150 ml water, about 1:18, 93 °C, 5 cups per sample, crust broken at 4 minutes.
The 2004 form scored ten attributes out of ten, totalling 100.
It has been superseded by the Coffee Value Assessment: SCA Standards 102, 103 and 104.
The CVA affective form caps at 72 points, not 100.
Specialty grade under the old rule needed 80 points and a physical grade.
There is no SCA band called "Premium".
Q Grader certificates are valid for 36 months, renewed by calibration, not by full retake.
CQI's current course description gives 20 examinations.

Frequently Asked Questions

Is the SCA 100-point scale still the standard? Not as the SCA's own standard. It has been superseded by the Coffee Value Assessment. It remains in wide use as industry custom during the transition.

What score makes a coffee specialty? Under the superseded protocol, 80 points and a physical grade. Under the Coffee Value Assessment there is no single score.

Why five cups per sample? To catch a defect present in some beans and not others. One tainted cup out of five is information a single cup cannot give.

Do Q Graders have to retake the whole certification every three years? No. The certificate is valid for 36 months and is renewed by passing a calibration course — two of three cupping flights.

Does Puerto Rican coffee have a typical cupping score? No source establishes one. This encyclopedia previously published a range on three separate pages and has withdrawn it from all of them.

Why does slurping matter? It aerates the coffee across the whole palate at once. It is technique, not performance.
