Dark roast. Sumatran coffees are some of the heaviest, smoothest, and most complex coffees in the world. The Sumatra coffee is rich in flavor as it is rich in coffee history. Amazingly enough, it was once thought to be lost to the world and it took over 100 years for the rare cultivar to be rediscovered, hidden amongst the lush jungle of Sumatra. This coffee has a thick and syrupy chocolaty mouth feel with a rich brown sugar taste. This gourmet coffee is widely known for its full-bodied texture, mild earthy notes, and deep-toned coffee aroma. It is low in acidity with a slight black pepper finish.
