A Broker’s Insider Advice
Finding the right green coffee supplier can make or break your roasting business. As a broker working with 200+ European roasters, I’ve seen buyers lose thousands on poor-quality beans. Here are the 5 most costly mistakes – and how to avoid them.
Red Flag #1: Vague Origin Details
What to watch for:
- No farm names/GPS coordinates
- Just “Colombian” or “Ethiopian” (no region/cooperative)
- Unverifiable “direct trade” claims
What to ask instead:
- “Can you share harvest photos or farmer contracts?”
- “What’s the elevation and processing method?”
Red Flag #2: No Moisture Testing
The risk:
- >12% moisture: Mold risk, stale flavors
- <10% moisture: Brittle beans, baked-tasting roasts
How to verify:
✔ Demand recent (≤30 days) lab reports
✔ Use a handheld moisture meter on samples
Red Flag #3: Defect Evasiveness
Critical defects per 300g:
|
Grade |
Allowable Defects |
Cost Difference |
|---|---|---|
|
Specialty |
0-5 |
+20-30% |
|
Commercial |
10-15 |
Base price |
Supplier red flags:
- “Roughly Grade 1” (no exact count)
- Rejects defect checker boards
Red Flag #4: “Too Good to Be True” Pricing
2024 Global Price Benchmarks:
- Colombian Excelso (Grade 1): 3.80 − 3.80−4.20/kg
- Ethiopian Yirgacheffe: 5.50 −5.50−6.80/kg
If prices are 15% below market:
Likely mixed-origin or old crop
or
May lack phytosanitary certificates
Red Flag #5: No Reshipment Guarantee
Essential contract terms:
- Quality arbitration (SCA standards)
- Replacement for lab-proven variances
- Force majeure clauses

FAQ
1. How common are defective green coffee shipments?
Industry data shows 30% of bulk orders have undisclosed defects (SCA, 2023). At Flavy, we reject 1 in 5 lots during pre-shipment checks.
2. Can’t I just trust "Grade 1" labels from suppliers?
No. “Grade 1” has no universal standard. Always:
- Request defect count per 300g
- Verify with photos/videos of sorted beans
- Our practice: We provide [before/after sorting images] for every lot.
3. What’s the biggest moisture-related mistake?
Assuming “dry climate = safe.” Even in arid regions, poor storage causes moisture spikes. Always:
✔ Test with a $150 moisture meter (like the [model we use])
✔ Reject bags with condensation inside
