About This Coffee
The Mandailing region of North Sumatra is famous for giling basah, the wet-hulled process unique to Indonesia. Because the parchment is hulled while still moist, Sumatran coffee develops its signature deep body, low acidity and earthy, spicy character.
After pulping, the beans rest overnight in their own mucilage, are washed, then dried only briefly before hulling at high moisture. This lot is “triple picked” — sorted and cleaned three times — for a clean, defect-free G1 grade. The result is a rich, comforting cup with dark chocolate, herbal spice and a full, syrupy mouthfeel.
