Fine Robusta Sample Evaluation Checklist for New Suppliers

A new supplier should not be approved from a tasting note alone. The first sample is the start of a verification process that should connect the coffee to a lot, process, physical condition and commercial offer.

This page focuses only on sample evaluation for a new Fine Robusta supplier.

Before opening the sample

Record:

• supplier;
• sample code;
• lot code;
• origin;
• crop or harvest;
• process;
• sample date;
• sample type;
• quantity represented.

If the supplier cannot provide the lot identity, note the limitation before evaluation.

Check packaging and condition

Inspect:

• package integrity;
• unusual odor;
• moisture exposure;
• contamination;
• labeling consistency.

A damaged sample should not be treated as representative without qualification.

Physical review

Depending on the buyer’s method, record:

• visible defects;
• foreign matter;
• moisture;
• water activity where available;
• size distribution where relevant;
• color;
• storage-related concerns.

Use a named method rather than a universal Fine Robusta threshold.

For the broader framework, continue to Fine Robusta grading.

Prepare a repeatable sensory test

Record the preparation method so the team can repeat it.

Useful fields include:

• roast date;
• rest time;
• grind;
• dose;
• water;
• temperature;
• contact time;
• evaluator;
• number of cups.

Separate description from approval

First describe the coffee:

• aroma;
• flavor;
• sweetness;
• bitterness;
• acidity;
• body;
• aftertaste;
• defects;
• cup-to-cup variation.

Then make the decision:

• reject;
• request another sample;
• approve for application testing;
• approve for commercial discussion.

Test the intended product

If the coffee is intended for espresso, milk drinks, filter, cold brew or blending, test that use.

A cupping result does not automatically predict operational performance.

Review process disclosure

Ask whether the sample documentation clearly explains:

• natural / washed / honey or other base process;
• fermentation where relevant;
• unusual substrates or interventions;
• drying;
• storage.

For broader processing disclosure, use Fine Robusta processing transparency.

Verify the commercial lot

Ask:

• Is this sample drawn from the lot that is for sale?
• How much of that lot is available?
• Has the lot been fully processed and stored?
• Will it be blended or altered before shipment?

This prevents showcase samples from being mistaken for shipment samples.

Request current commercial terms

Only after the sample is technically interesting should the team compare:

• quantity;
• minimum practical shipment;
• price;
• delivery basis;
• payment terms;
• lead time;
• packaging.

The quality decision and commercial decision can then be documented separately.

New-supplier risk flags

Flag:

• changing lot information;
• score claims without sample identity;
• unexplained producer names;
• unverified certifications;
• refusal to provide a pre-shipment sample;
• unclear exporter role;
• inconsistent documents.

Re-sampling trigger

Require a new sample if:

• lot changes;
• crop changes;
• process changes;
• storage changes materially;
• supplier substitutes coffee;
• the original sample is no longer representative.

Evaluation template

OCC application

For Cambodian Fine Robusta, a disciplined sample workflow can make a smaller origin easier for buyers to trust. The sample should lead upward to the formal supplier due-diligence Owner and then to Wholesale, not create another generic sourcing Owner.

Bottom line

A new-supplier sample is valuable when it is identified, repeatably evaluated, connected to the saleable lot and followed by clear commercial verification.
