The fine robusta standards are a two-part test developed by the Coffee Quality Institute (CQI) with the Uganda Coffee Development Authority (UCDA): a physical grading of a 350 g green sample that allows no primary defects and only a few secondary ones, and a sensory evaluation on a dedicated robusta cupping form where 80 points or more, scored by licensed Q Robusta graders, earns the “Fine Robusta” label.
This explainer takes the standard apart: its origin, the green grading, the ten cupping attributes, the score bands, how to read a score sheet, and where the system has limits. For the wider trend and sourcing advice, see our pillar on fine robusta Vietnam.

Where Do the Fine Robusta Standards Come From?
CQI began developing robusta quality protocols in Uganda in 2010, and Q Robusta grader and instructor courses followed from 2012. The result was a robusta-specific version of the specialty arabica system: green grading, a cupping form, a sensory lexicon and licensed graders.
The grader program itself has just changed hands. Since 1 October 2025 the Specialty Coffee Association (SCA) operates the “evolved” Q Grader program, built on its Coffee Value Assessment (CVA) introduced in 2023. Both Q Arabica and Q Robusta graders qualify for the evolved program, and existing certifications stay valid until their printed expiry date.
As of October 2026, scores on Vietnamese fine lots, including our own 84.5-point lot, come from the CQI robusta form, so this post describes that form.
What Does the Green Grading Require?
A 350 g green sample is spread on a tray, every defective bean is sorted into one of two categories, and the counts are converted to “full defect” equivalents. Category 1 (primary) defects are the serious ones: full black, full sour, dried cherry or pod, fungus-damaged beans, foreign matter and severe insect damage. Category 2 (secondary) defects are partial blacks and sours, parchment, floaters, immature beans, withered beans, shells, broken or chipped beans, hulls and slight insect damage (see our entry on defects in coffee beans).
In the arabica system the robusta protocol follows, one bean equals one full defect for most Category 1 types, while Category 2 types need three, five or ten beans per full defect. Our reading of the CQI/UCDA robusta protocol is that Fine Robusta allows zero Category 1 defects and no more than five full Category 2 defects, with a looser allowance for the Premium tier; confirm the exact current limits with your grader. The roasted sample is also checked for quakers, the pale, underdeveloped beans from unripe cherry.
The protocol also sets a moisture window. In practice, Vietnamese exporters ship at 12.5% or below, the ceiling in ICO Resolution 420, which sets 8–12.5% moisture and a target of no more than 150 defects per 300 g for commercial robusta graded by the Vietnam and Indonesia methods. That gap shows how far a fine grade sits from a commercial one.
| Tier | Cupping score | Green grading (350 g) | Who scores it |
|---|---|---|---|
| Fine Robusta | 80 or above on the robusta form | No Category 1 defects; limited full Category 2 defects (our reading: max five) | Licensed Q Robusta graders |
| Premium Robusta | 70–79.99 | Looser defect allowance | Licensed Q Robusta graders |
| Commercial (ICO Res. 420 target) | Not cupped for grade | Up to 150 defects per 300 g; moisture 8–12.5% | Exporter/inspector by national standard |
What Does the Robusta Cupping Form Measure?
Ten attributes, each scored on a quality scale, modeled on the specialty arabica form but with two attributes that exist only for robusta: salt/acid and bitter/sweet.
| Attribute | What the grader is judging |
|---|---|
| Fragrance/Aroma | Dry grounds and the “break” after adding water; intensity and quality |
| Flavor | Taste and retronasal aroma together: intensity, quality, complexity |
| Aftertaste | Length and quality of what remains after swallowing |
| Salt/Acid | Balance between salty and acidic perception; acid preferred over salt |
| Bitter/Sweet | Balance between bitterness and sweetness; sweet preferred over bitter |
| Mouthfeel | Weight and texture of the liquid on the palate |
| Balance | How flavor, aftertaste, the two ratios and mouthfeel work together |
| Uniform Cup | Consistency across the five cups of the sample |
| Clean Cup | Absence of off-flavors and defects in each cup |
| Overall | The grader’s holistic rating of the sample |
The mechanics follow the arabica form the robusta form was built from. Quality attributes run on a 6–10 scale in quarter-point steps (6 “good”, 7 “very good”, 8 “excellent”, 9 “outstanding”), and uniform cup and clean cup award 2 points per clean cup across five cups.
Salt/acid, bitter/sweet and mouthfeel also carry intensity marks (high or low, heavy or thin) that describe the cup without changing the score. Defective cups are deducted as a taint or a fault, multiplied by the number of affected cups; the final score is the attribute total minus those deductions.
Samples are roasted to a standard level, cupped as five cups at a fixed coffee-to-water ratio, and scored by licensed graders who calibrate together; a certified lot score typically comes from several graders, not one.
Score Bands: What 80, 84 or 86 Points Mean
The form’s final-score key, as reproduced by the Swiss roaster-trainers at Kaffeemacher, reads as follows.
| Final score | Classification |
|---|---|
| 90–100 | Outstanding (Very Fine) |
| 80–90 | Fine |
| 70–80 | Very Good (Premium) |
| 60–70 | Average (Usual Good Quality) |
| Below 60 | Fair, commercial and exchange grades |
For scale: the top robusta entries at the 2026 Vietnam Amazing Cup scored 85.94, and our fine robusta anaerobic Vietnam lot scored 84.5 under the CQI protocol. Most fine Vietnamese export lots sit between 80 and 85; anything quoted above 87 deserves a second cupping.
How Buyers Read a Score Sheet Against the Fine Robusta Standards
- Check the header first: form used, date, roast level, sample or lot ID, and the grader’s license number. A score without these is a number, not a certificate.
- Look at where the points come from. Uniform cup and clean cup are near-automatic 10s for a sound lot, so an 80 built on them with 7.0s in flavor and aftertaste is a weaker coffee than an 80 with 7.75 flavor and a small clean-cup deduction.
- Read the intensity marks. “Acid high, salt low” and “sweet high, bitter low” tell you more about espresso behavior than the score does.
- Check the defect line and cup count. One tainted cup out of five is a warning about lot uniformity, not a rounding error.
- Match it to the green report and the sample. The score should travel with a green grading report, and the pre-shipment sample (PSS) should match the type sample you approved.
- Cup it yourself. Use the same form, blind, next to your current robusta.

Where the Standards Fall Short
- Panel variation. Calibrated graders still differ by a point or two, and roast level, water and sample age move scores. Treat 83.5 versus 84.5 as the same coffee.
- Sample versus lot. A score describes the cups on the table. Tank-to-tank variation in fermented lots can be larger than the margin that separates “fine” from “premium”.
- Form differences. A CQI robusta-form score, a legacy SCA-form score and a CVA affective score are not interchangeable.
- No safety or traceability content. The standards say nothing about moisture at loading, water activity, mold risk, residues or farm location; ask for a certificate of analysis and EU Deforestation Regulation geolocation data separately.
- Espresso is not on the form. Some robustas scoring 78–80 pull better shots than lighter 83s; score first, then test the brew method you sell.
Frequently Asked Questions
What are the fine robusta standards in one sentence?
A 350 g green sample with no primary defects and only a few secondary ones, plus a cupping score of 80 or more on the CQI robusta form from licensed Q Robusta graders. Lots scoring 70–79.99 fall in the Premium band, and both parts of the test must be met.
Who can issue a Fine Robusta score?
Licensed Q Robusta graders, historically trained and licensed through CQI and, since October 2025, through the SCA’s evolved Q Grader program. Existing licenses remain valid until their expiry date. Suppliers cup internally too, as we do, but a score presented as a Fine Robusta result should name the graders and the form used.
Does an 80-point score guarantee a clean, safe lot?
No. The score covers sensory quality and the green grading covers visible defects. Neither certifies moisture at shipment, water activity, mold or residue status, or traceability. Request a certificate of analysis, the moisture reading at loading and, for EU buyers, farm geolocation data.
How do the SCA’s CVA changes affect robusta scores?
Since 1 October 2025 the SCA runs the Q Grader program on its Coffee Value Assessment, which separates physical, descriptive, affective and extrinsic assessments. Q Robusta graders qualify for the evolved program. For now, most Vietnamese fine lots still carry CQI robusta-form scores; when comparing offers, make sure the scores come from the same form.
Bottom Line
Fine robusta standards are useful precisely because they are specific: a defect count, a form, a threshold and a licensed grader. Use them as a filter, not a verdict. Read the full sheet, match it to the green report and sample, and cup the coffee as you will sell it. Related reading: anaerobic robusta coffee for how fermented lots are evaluated before purchase.
