These beans are some of the heaviest, smoothest, and most complex coffees in the world. Most of the coffees from Sumatra are dry-processed, but some are semi-washed. The majority of Sumatran coffee is marked Mandheling or Lintong and is grown inland from the southern coast. Sumatra coffee grown farther west is usually marked Gayo Mountain. Sumatra Gayo coffee is described as sweet and clean.
Sumatra is one of the great romance coffees of the world. It is not simply that the Indonesian Island of Sumatra embodies a Conradian romance of the unfamiliar. When it is at its best the coffee itself suggests intrigue, with its complexity, its weight without heaviness, and an acidity that resonates deep inside the heart of the coffee, enveloped in richness, rather than confronting the palate the moment we lift the cup.
