CQI Robusta Cupping Form: Understanding the 10 Scoring Criteria for Fine Robusta

Introduction: The Science of Robusta Cupping

The CQI Robusta Cupping Form represents a systematic approach to evaluating Robusta coffee quality. Developed by CQI in collaboration with the Uganda Coffee Development Authority (UCDA)—recognizing that Robusta originated in Uganda—this specialized form differs significantly from the Arabica cupping form. Understanding these criteria is essential for producers, traders, and coffee professionals seeking to navigate the Fine Robusta certification process.

The 10 Scoring Attributes

The CQI Robusta Cupping Form evaluates ten important flavor attributes:

1. Fragrance/Aroma

This category assesses the olfactory sensations of the dry grounds (fragrance) and the wet crust (aroma). Evaluators note the intensity and quality of the aromatic profile.

1. Flavor

Flavor represents the combined perception of the coffee's taste characteristics—the overall sensory impression from the first sip through swallowing.

1. Aftertaste

Aftertaste measures the duration and quality of positive flavor sensations that remain after the coffee is expectorated. A long, pleasant aftertaste indicates higher quality.

1. Salt/Acid Aspect Ratio

This is a distinctive feature of the Robusta cupping form. CQI considers that Robusta contains more potassium than Arabica. This criterion reflects the reality of Robusta's chemical composition and evaluates the balance between salty and acidic notes.

1. Bitter/Sweet Aspect Ratio

Another Robusta-specific criterion, this evaluates the balance between bitterness and sweetness. Unlike Arabica cupping, where bitterness is typically considered a defect, in Robusta it is evaluated as a qualitative aspect.

1. Mouthfeel

Mouthfeel assesses the tactile sensation—the body and texture of the coffee on the palate. This includes factors like viscosity and weight.

1. Balance

Balance evaluates how well the various flavor attributes work together harmoniously. A well-balanced coffee has no single attribute dominating in an unpleasant way.

1. Uniform Cups

This criterion checks for consistency across multiple cups from the same sample. Significant variation suggests quality control issues.

1. Clean Cups

Clean cups measures the absence of defects or off-flavors. A clean cup is free from taints and foreign tastes.

1. Overall (Personal Evaluation)

This is the cupper's holistic assessment of the coffee, integrating all previous attributes into a final personal score.

Scoring Scale and Quality Classification

Each attribute is scored on a scale, and the total score determines the coffee's classification:

Score Range | Classification

70-80 points | Premium Robusta

80-90 points | Fine Robusta

90+ points | Very Fine Robusta

Robusta-Specific Cupping Protocols

The Robusta cupping protocol includes several specific requirements that differ from Arabica cupping:

Roast Profile: Robusta beans are considerably denser than most Arabica beans and present greater resistance to heat. The surface of Robusta whole beans needs to reflect a considerably darker roast than Arabica whole beans to achieve similar flavor development.

Roast Color: Robusta whole bean roast color should be medium to medium-dark, not light to medium-light as is common for Arabica cupping roasts. On the M-Basic Agtron scale, a Robusta whole bean reading of approximately 48 is needed to produce a ground reading of approximately 78.

First Crack: Those accustomed to sample roasting Arabica should note that the first crack is not as pronounced and dramatic in Robusta. With Robusta, the first crack seldom reaches a crescendo, and the second crack is also very subdued.

The Role of the Q Robusta Grader

A Q Robusta Grader is a highly trained and calibrated coffee taster who evaluates coffee using the SCA's cupping standards and protocols. The Q Robusta course includes 20 exams in 9 modules to assess students' job skills, including cupping protocols, olfactory and gustatory senses, identification of defects in green coffee, identification of defects in roasted samples, and the combination of coffee acids.

Conclusion

The CQI Robusta Cupping Form represents a sophisticated framework for evaluating Robusta quality on its own terms—not as a lesser version of Arabica, but as a distinct coffee species with its own quality parameters. Understanding these ten scoring criteria is essential for anyone seeking to produce, evaluate, or trade Fine Robusta coffees.
