Aceh, in northern Sumatra, is an incredible region for coffee production. The average farm is one hectare, 80% of producers within northern Sumatra are women, and 95% of producers are smallholders. The region is diverse, geographically speaking. It is surrounded by beaches with a swampy inland, and the Barisan Mountains make up the inner two-thirds of the area. Coffee is grown on this volcanic mountain amongst the rainforest. One of the notable features of this area is Lake Taboa, the largest volcanic lake in the world.
