Sumatra Espresso:
Flavor Profile & Dial-In Guide
Sumatran coffees, processed via the unique wet-hulling method, produce some of the earthiest, most complex profiles in the world. Mandheling and Gayo coffees have a distinctive cedar, earth, and dark chocolate character. As espresso, Sumatra provides exceptional body and works beautifully as a base in dark blends.
