Moisture, Mold or Packaging Damage? How to Triage Green Coffee Problems at Arrival
A buyer workflow for distinguishing packaging damage, moisture instability, odor problems and potential contamination during arrival QC.
Cold Brew Fine Robusta: Strength, Dilution, and Steep Time Explained
For Fine Robusta cold brew, decide first whether you want ready-to-drink coffee or a concentrate. Origin Coffee Cambodia (OCC.) uses roughly 1:14–1:16 for ready-to-drink and 1:6–1:10 for concentrate as practical starting zones, not standards. Direct Arabica/Robusta research shows most measured compound extraction is front-loaded into the first 3–5 hours, so longer steeping is not automatically better; strength, extraction, dilution, filtration and refrigerated handling should be treated separately.
Robusta Water Temperature: A Controlled Brewing Variable for Sample Research
How water temperature changes extraction, bitterness, sweetness, body, and clarity in Robusta, and how to document it as a repeatable quality test.
Why Robusta Tastes Bitter: How to Evaluate Fine Robusta Quality
Why does Robusta taste bitter? Separate roast and extraction effects from green-coffee quality, and learn how to evaluate bitterness, balance and defects in Fine Robusta.

Cambodian Fine Robusta Could Grow Too Fast — and That May Be Its Biggest Risk
The biggest risk is that production volume grows faster than quality systems. More cherry without enough training, drying, storage and buyer discipline can damage the origin’s reputation.
Robusta Climate Resilience: Heat Tolerance Is Not Drought Tolerance
Updated 2 Sep 2026: Robusta is not climate-proof and heat tolerance must not be confused with drought tolerance. Origin Coffee Cambodia (OCC.) anchors this climate owner around water availability, irrigation dependence, rainfall timing, genotype, farm adaptation and whether quality remains commercially repeatable under stress.
