Warehouse Humidity for Cambodian Green Coffee: Managing Storage Risk

Green coffee is hygroscopic, which means it interacts with the surrounding environment. For Robusta Cambodia, warehouse humidity can affect stability even after careful drying.

Focus on environment and exposure time

Short periods of humid air may be less serious than prolonged storage under poor conditions. Buyers and exporters should track warehouse condition, bag protection and how long the lot remains exposed.

Prevent condensation points

Coffee stored directly on floors or against exterior walls can face localized moisture risk. Pallets, spacing and building maintenance help reduce that exposure.

Monitor the coffee, not only the room

Environmental readings are useful, but periodic inspection of bags, odor and green moisture gives a better picture of whether the coffee is actually changing.

Warehouse controls

• Keep coffee off the floor
• Separate from exterior walls
• Repair roof and water leaks quickly
• Avoid strong odors
• Monitor pests
• Record storage dates
• Recheck longer-held lots

Good humidity management helps Robusta Cambodia maintain quality from post-harvest preparation through final roasting.
