Oren's Sumatra Mandheling is low in acidity and takes on the earthiness of its surroundings. Sumatra is the world's most full-bodied coffee. We have been purchasing Sumatran coffee since we opened and this one is a very nice and archetypal Sumatran coffee. It is rustic and herbal, with a syrupy and heavy body. Mandheling style coffees come from Aceh and other northern parts of the island.
