This is an estate-grown coffee from Aceh Province, Sumatra’s most famous and prolific production area for specialty wet-hulled profiles. Unlike most coffee in the area, which is traditionally grown by hundreds of smaller farmers and gradually consolidated through processing, collection, and milling, Central Sumatera Coffee operates a 100-hectare estate right in Bener Meriah regency, where they can control the genetics, harvesting, and post-harvest techniques to perfection.
This is a super unique processing style that uses anaerobic fermentation, yeast inoculation and a co-fermentation with powdered dried fruit to achieve a totally distinct, heavily flavored coffee with perfume like fragrances and sweet, fresh, lychee fruit.
CSC manages processing on their own estates. The Bener Meriah estate employs 30 pickers during harvest months, and six specialists for processing. Most of their estate coffee is wet-hulled in the traditional fashion, but this microlot took an entirely different route, blending multiple unique fermentation techniques to augment the final cup, and ultimately processed as a semi-washed.
After picking, the cherry was depulped and fermented anaerobically in sealed containers with the addition of Lallemand Saccharomyces cerivisiae, for a total of 48 hours. Once the first fermentation cycle was complete, the containers were opened, dried lychee fruit powder was added, and then they were resealed for another 12 hours. After the full multi-stage 60-hour fermentation, the containers were opened, the parchment washed clean and moved directly to raised screen tables to dry. Once the parchment dried to 35% moisture content it was de-hulled (this is the wet-hulled part) and allowed to finish drying as a raw seed on the raised tables.
Central Sumatera Coffee (CSC) is a young group, with young leadership. It was originally founded in 2015 by Enzo Sauqi Hutabarat, then a University student with family ties to Bener Meriah. Aware of the growing demand across greater Indonesia for Sumatra’s best coffees, he gravitated toward Aceh as a culture and potential business environment. Until 2020 CSC only sold coffee domestically, but starting in 2021 they began to export as well, selling bits of coffee to the Middle East, Europe, Asia, and finally, in 2024, the United States, via Royal Coffee, for the first time.
CSC buys coffee from smallholders like a typical processor does. However, CSC also operates 3 large estates of about 100 hectares each: one in Bener Meriah, where this lot was produced; as well as 2 others in North Sumatra province, near Lake Toba. Their farms are organized varietally, allowing them to maintain unique genetic separations during harvest and processing.
Typical smallholder coffee in Aceh tends to be a blend of traditional heirloom cultivars, most of which are catimor hybrids, and this gives much of the area’s coffee a set of common characteristics that can be hard to transcend for a single producer. In CSC’s case, they have the genetic isolation, and the volume from such a large estate, to help them produce something unique. Even with similar processing styles as the collectors and coops around them.
