How Moisture and Storage Affect Robusta Trade Quality

Moisture and storage determine how well green Robusta preserves its physical and sensory condition between milling and roasting.

Coffee that is too wet or exposed to humidity can face instability, mold risk, and quality deterioration. Very dry coffee may roast and age differently.

Warehouse temperature, odors, packaging, and storage time also matter.

Buyer takeaway: request current moisture data, storage conditions, packaging, and a representative sample. Trade quality is not fixed at export grading; it can change before the coffee reaches the roaster.
