Sumatra Mandheling Green Coffee Beans

Sumatra green coffee beans are some of the most distinctive and unique coffees. Grown in the Aceh highlands of the Sunda Islands, of which Sumatra is the second largest, unroasted coffees from Sumatra are often described as low-toned, highly aromatic, and packed with flavor.


Wet-hulled Coffee Process (Giling Basah)

Most green coffee in Sumatra is processed using the wet-hulled process (also known as Giling Basah). The process contributes to the unique character of Sumatra Mandheling green coffee. The wet-hulled process shares some similarities with washed processing but also takes into account Indonesia's humid climate. De-pulped coffee beans are first dried to 30-40% moisture (usually 11-12% in the washed processing) and then hulled to remove the parchment layer. The resulting raw green coffee beans can be more susceptible to moisture and temperature fluctuations.


Sumatra coffee flavor notes that arise from the wet-hulled process usually include earthy and spicy tones that express rich, rustic, and sweet characteristics in the cup.


Coffee Production in Sumatra

Sumatran coffee production has a long history, extending to the 17th century when the Dutch East India Company imported coffee to Indonesia. Today, Sumatran coffee quality is defined by a graded scale from G1 to G6, with G1 being the highest designation. Quality classifications are further separated into double-picked (DP) or triple-picked (TP). The designation refers to the number of times the Indonesian coffee beans are hand-sorted to remove defects.


Indonesian Green Coffee

The key regions that produce Indonesian green coffee are Aceh, North Sumatra, South Sulawesi, West Java, Bali, and Flores. Green coffee from Java is exceptionally well-known for its role in disseminating Indonesian coffee production throughout the archipelago. In contrast to the long history of coffee from regions like Sulawesi and Sumatra, green coffee from Bali, a relatively newer coffee region in Indonesia, mainly produces small-batch, limited-scale coffee quantities.
