Indonesian Golden Mandheling Coffee Beans: Flavor and Audience

Golden Mandheling is a wet-hulled coffee from the highlands of Sumatra, near Lake Toba and the Gayo region. The unusual Giling Basah process, where parchment is removed while the bean is still moist, gives the coffee its deep green color and heavy body. Growers pick ripe cherries and ferment them briefly before the wet-hulling step, which shapes the earthy, savory cup the region is known for.

The taste is bold rather than delicate, so it suits drinkers who enjoy espresso, moka pot, or French press.
