About coffee from Indonesia

Indonesian coffee, especially from Sumatra, is often wet-hulled, a local method that hulls the beans while they're still wet. That gives the earthy, full-bodied, low-acid cup Sumatra is known for.

What the process means

In a natural (dry) process, the whole coffee cherry dries in the sun with the fruit still on the bean. That usually gives a heavier body and riper, fruitier flavors like berry and tropical fruit.
