Green Coffee Storage
How temperature, humidity, packaging, oxygen exposure and time affect green coffee during storage and transport.
The goal of storage
Good storage aims to preserve physical integrity and minimise unwanted chemical and moisture changes before roasting.
Temperature and humidity
Heat and changing humidity can accelerate deterioration and moisture exchange. Stable, moderate conditions are generally preferable to large environmental swings.
Packaging
Jute, GrainPro-type barrier bags and other packaging systems are used according to supply-chain requirements. Barrier packaging can reduce moisture and odour exchange compared with traditional woven sacks.
Ageing
Green coffee does not remain unchanged indefinitely. Storage time, oxygen, moisture, temperature, packaging and the coffee's initial condition all influence how it develops.
