From Green Bean to Score: Inside CQI Robusta Evaluation

20. From Green Bean to Score: Inside CQI Robusta Evaluation

Introduction

Follow a Robusta lot's journey from harvest to final Fine Robusta score, and you'll see exactly how much careful evaluation stands behind that number.

Why This Matters

Seeing the full journey helps buyers appreciate the depth of quality control behind a Fine Robusta claim, beyond just the final score itself.

Main Explanation

The journey starts at the farm, where cherry selection and post-harvest processing — fermentation, drying, and sorting — set the ceiling for how high a lot can eventually score. Even excellent genetics and terroir can't overcome poor processing at this stage.

From there, a representative sample is drawn — 350 grams of green coffee for physical analysis, plus a separate portion for moisture testing and roasted quaker counting. Technicians inspect this sample for primary and secondary defects, verify moisture falls within the expected range, and check bean size consistency against contractual specifications.

If the sample passes physical grading, it moves to sensory evaluation: certified Q Robusta Graders roast and cup the coffee following standardized protocol, scoring attributes like salt/acid ratio, bitter/sweet ratio, and mouthfeel across multiple bowls to check for consistency.

Finally, physical and sensory results are combined into a formal grading report. A lot achieving a sensory score generally at or above 80 points, alongside passing physical specifications, earns Fine Robusta classification — a designation that can now follow that coffee through export documentation, contracts, and marketing all the way to the final buyer's cup.

Comparison Table

Real Examples

A cooperative that improves its fermentation consistency at the farm level may see the same genetic material and terroir produce a meaningfully higher score than in previous harvests — proof that the journey from bean to score genuinely starts long before any lab work begins.

Faq

Where does quality potential actually begin?

At the farm, through cherry selection and post-harvest processing decisions.

How much of the final score depends on processing versus genetics?

Both matter significantly, but processing consistency is often the more immediately controllable factor.

Does every lot go through the same evaluation steps?

Yes — the standardized process applies consistently to maintain comparability across lots and countries.

Can a lot be re-evaluated if initial processing issues are fixed?

Future harvests can certainly benefit from processing improvements, though re-grading an existing lot depends on specific lab and contractual arrangements.

Is this full journey documented for buyers?

Reputable suppliers typically provide documentation covering both physical and sensory grading results.

Conclusion

A Fine Robusta score isn't just a lab result — it's the final checkpoint in a journey that starts with careful farming and processing decisions long before any coffee reaches a cupping table.
