Sumatran coffee has long been recognized worldwide as one of the coffees with a distinctive character and flavor profile. Its uniqueness lies in the combination of subtle dark chocolate notes and a low level of acidity.
The diversity of coffee variants from various highlands in Sumatra offers a different authentic sensation in every sip. Ranging from touches of spice to chocolate, these coffees are the result of natural wealth and the traditional processing styles unique to the island of Sumatra.
History and Uniqueness of Sumatran Coffee
The history of coffee in Sumatra began during the Dutch colonial era, specifically when Arabica coffee seeds were first planted in the Mandailing region in the 19th century. Since then, Sumatra has transformed into one of the high-quality coffee producers supplying global market demands.
The primary uniqueness of Sumatran coffee compared to others lies in its processing method called Giling Basah or wet-hulled. This technique produces coffee beans with low acidity but a thick and intense body.
Farmers typically grow the coffee under the shade of other trees and manually harvest only the red cherries to maintain quality. The combination of fertile volcanic soil and high rainfall gives Sumatran coffee its legendary earthy and spicy aroma.
