Gayo Highlands (Aceh) Coffee
The Gayo Highlands around Lake Tawar in Aceh province form Sumatra's largest and most quality-consistent Arabica region. Smallholders — organized in some of the world's biggest Fairtrade-organic cooperative structures — process by giling basah (wet-hulling), the uniquely Indonesian method behind Sumatra's heavy, earthy signature.
Gayo's higher altitudes and cooperative quality systems produce a cleaner take on the Sumatran style than classic Mandheling, and full-washed experiments increasingly reveal a bright, fruited side the wet-hulled tradition conceals. The region holds a protected geographical indication.

Gayo Highlands (Aceh) — frequently asked questions
What makes Gayo different from Mandheling?
Higher average altitude, cooler climate, and strong cooperative processing standards — the same wet-hulled style, executed with more consistency and cup clarity.
What is wet-hulling?
Giling basah: parchment is stripped at ~35% moisture and the naked bean finishes drying exposed — compressing drying time in Sumatra's humidity and creating the region's heavy, low-acid profile.
