From 1976 to 2005, Aceh was caught in violent conflict with the Indonesian government. Many families fled their farms and moved to cities like Medan. Even after peace was declared in 2005, poverty remained widespread.
In 2006, 50 farmers from five villages founded the Permata Gayo Cooperative. Their goal was simple but urgent: rebuild the region’s coffee industry and bring economic stability back to Aceh.
Region
The region experiences a tropical climate with high rainfall and humidity, but little temperature variation. This consistent climate is beneficial for coffee growth. Coffee in Aceh is grown at altitudes ranging from 1,200m to 1,500m, which is ideal for coffee production. The volcanic soil of the region is rich in nutrients, contributing to the rich flavour of the coffee beans
Process Info
- Unique to Sumatra: This process is not widely used in other coffee-producing regions.
- Drying Stages: The beans are dried at specific humidity levels (e.g., 30%, 20%, and finally 11%) as they are transported further down the mountain.
- Blue-Green Hue: The process gives the raw coffee beans a distinct blue/green color.
- Flavor Profile: The resulting coffee often exhibits an earthy, rounded flavor with a strong body.
- Moisture Content: The Giling-Basah process is characterized by hulling the beans while they are still relatively wet (e.g., around 40% moisture).
- Fermentation: The process involves some fermentation during the drying stages, which contributes to the unique flavor profile.
