The Sumatra Lintong Mutu Batak originates from carefully selected smallholder farmers near the town of Lintongnihuta in North Sumatra Province. Nestled on the southern shores of Lake Toba—the world’s largest volcanic lake—this region benefits from fertile volcanic soil and elevations ranging from 1,000 to 1,300 meters, creating ideal conditions for coffee cultivation. Each farmer tends to small plantations of two to four hectares, with about 1,000 coffee trees per hectare. These dedicated producers grow, harvest, and depulp their coffee on-site. After depulping, the coffee is fermented overnight, washed the following day, and partially dried to reduce surface moisture before being delivered to the production facility.

Once at the facility, every batch undergoes strict inspection to meet quality standards. Approved lots are initially dried in greenhouses to around 40% moisture, then hulled and returned for further drying until they reach 12–13% moisture content. The coffee is then sent to the warehouse in Medan, where it is inspected again and stored for two months to stabilize. Finally, it undergoes meticulous hand-sorting, final grading, and bagging in preparation for export. Known for its larger screen size (15/16), Mutu Batak offers vibrant acidity, a full-bodied profile, and a sweet, lingering finish.
