Why Storing Green Coffee Properly Matters

Green coffee’s quality depends largely on how it’s stored. Being a hygroscopic product, it is highly sensitive to air moisture.

The beans are typically dried to about 12% moisture before shipment, hence it’s vital not to let them take on excess moisture in storage.

Improper storage can lead to deterioration of quality or even mold growth. Green coffee is also absorbent and can easily adopt strong odors.

“As a result, we know that the critical moments when conventionally packed coffee is exposed to quality degradation are inland transportation, port delays, and extreme temperatures and humidity during transshipment.” – Renaud Cuchet

In addition, exposure to heat and direct sunlight can affect the freshness and quality of green coffee.

To store smaller quantities of green coffee: keep them in a cool, dry, dark place away from direct sunlight and heat; elevate them off the ground; avoid any water sources or humidity; and make sure they aren’t near anything with a strong odor.
