Key Criteria CQI Uses to Score Fine Robusta Beans

6. Key Criteria CQI Uses to Score Fine Robusta Beans

Introduction

Fine Robusta scoring rests on a specific set of criteria — here's a closer look at what graders are actually evaluating.

Why This Matters

Knowing the specific criteria helps buyers and roasters understand what a high score actually represents in terms of flavor and quality.

Main Explanation

CQI's Fine Robusta protocol evaluates coffee across attributes adapted specifically for Robusta's sensory profile. Fragrance and aroma capture the coffee's smell both dry and after brewing. Flavor and aftertaste assess the taste experience during and after tasting. Salt/acid ratio replaces the traditional acidity score used for Arabica, reflecting Robusta's different chemical composition. Bitter/sweet ratio similarly captures Robusta's characteristic balance between bitterness and sweetness, rather than relying on sweetness alone.

Additional criteria include mouthfeel (body and texture), uniformity (consistency across cups from the same lot), and overall balance — how well the individual attributes work together rather than in isolation.

On the physical side, criteria include primary and secondary defect counts, moisture percentage, and bean size uniformity — all assessed against strict thresholds specifically calibrated for Fine Robusta classification, distinct from standard commercial grading criteria.

Comparison Table

Real Examples

A lot with excellent flavor and aftertaste but a poor bitter/sweet balance might still score respectably, but likely below the Fine Robusta threshold if that imbalance is pronounced.

Faq

Why does Robusta use salt/acid ratio instead of acidity?

Because Robusta's chemistry produces a different, less acidity-driven flavor profile than Arabica.

Is uniformity really part of the score?

Yes — consistency across cups from the same lot is an important quality indicator.

Do all criteria carry equal weight?

Weighting can vary somewhat, but each criterion contributes meaningfully to the total score.

Are physical criteria as important as sensory ones?

Yes — a lot must pass both physical and sensory criteria to earn Fine Robusta status.

Can a lot excel in some criteria but still miss Fine Robusta status?

Yes — the cumulative score and defect limits both matter for final classification.

Conclusion

Fine Robusta's criteria are designed specifically around Robusta's own chemistry, not simply borrowed from Arabica standards — which is exactly why the category feels genuinely distinct in the cup.
