Coffee Value Assessment (CVA) Calculator

The Coffee Value Assessment (CVA) is the SCA's updated coffee evaluation framework, formalised in 2024 as SCA Standards 102, 103, and 104. The Affective Assessment (Standard 104) asks evaluators to rate their personal preference for each sensory attribute using a 9-point hedonic scale, from 'Dislike Extremely' (1) to 'Like Extremely' (9). This shifts the focus from objective quality measurement to measurable consumer preference.

A hedonic scale measures liking or preference rather than quality. The 9-point hedonic scale, developed by sensory scientists at the U.S. Army Quartermaster Corps in the 1950s, is one of the most widely validated tools in consumer research. The SCA adopted it for the CVA to align coffee evaluation more closely with how consumers actually experience and purchase coffee, making the data more actionable for producers and buyers.

The Affective Score is the mean of all eight attribute hedonic ratings, expressed as a percentage of the maximum possible score (9). Formula: Score = (mean rating / 9) × 100. A coffee where every attribute is rated 7 ('Like Moderately') would score approximately 77.8. A perfect score of 100 requires all eight attributes rated at 9 ('Like Extremely').

The 2004 cupping form asks 'how good is this coffee?' It uses a 6–10 quality scale across seven scored attributes, plus per-cup checks for uniformity, cleanliness, and sweetness, and subtracts defect penalties. The CVA asks 'how much do I like this coffee?' It uses a 1–9 preference scale across eight attributes and applies deductions for non-uniform cups and defective cups. The 2004 form targets trained judges assessing commercial quality; the CVA is designed to capture both expert and consumer preference data.

The CVA Affective Module (SCA Standard 104-2024) evaluates eight attributes: Fragrance (orthonasal aroma of the dry, ground coffee), Aroma (orthonasal aroma of the brewed coffee), Flavor, Aftertaste, Acidity, Sweetness, Mouthfeel (the tactile perception of viscosity, texture, and astringency in the cup), and Overall. Each is rated independently on the 9-point hedonic scale.

The CVA does not use the same 80-point specialty threshold as the 2004 form. The affective score reflects personal preference, not a pass/fail quality standard. Coffees with a mean affective rating of 7 or above (scoring approximately 77.8 and higher) generally represent coffees that trained evaluators like moderately to extremely. The CVA is intended to complement, not replace, grading systems used for commercial classification.

In a standard CVA flight, five cups of each coffee are prepared. Cup-level quality issues reduce the final score. Non-uniform cups (where the flavor in one cup differs noticeably from the others) deduct 2 points each. Taint-level defects, which are detectable off-notes that do not make the cup unacceptable, deduct 2 points per affected cup. Fault-level defects, which are severe defects that render a cup unacceptable or undrinkable, deduct 4 points per affected cup. These deductions are applied after the affective score is calculated: Total Score = Affective Score minus (non-uniform x 2) minus (taint-level x 2) minus (fault-level x 4).

A taint-level defect is an off-flavor or off-aroma that is detectable but does not make the cup unacceptable. Examples include slight fermentation notes, mild mustiness, or subtle phenolic hints. A fault-level defect is a severe defect that makes the cup unacceptable to consume. Examples include strong fermentation, full phenolic/medicinal character, mold, or foreign contamination. Taint-level defects subtract 2 points per affected cup; fault-level defects subtract 4 points per affected cup.

This calculator uses the CVA Affective Module scoring logic (SCA Standard 104-2024) for reference and practice. Official SCA competitions and Q Grader exams use calibrated protocols, certified forms, and licensed evaluators.
