What Is The Sumatran Coffee?

Sumatran Coffee

Sumatran coffee refers to any coffee that is grown and produced on the Indonesian island of Sumatra. It is a popular and well-respected variety of coffee that has gained a loyal following among coffee connoisseurs around the world.

Sumatran is the largest island in Indonesia and is situated in the western part of the country. It has a tropical climate, perfect for growing coffee. Coffee production on the island dates back to the early 17th century when Dutch colonizers introduced coffee plants from Yemen.

Origin of the Beans

The coffee beans used in Sumatran coffee come from the Coffea arabica species, which is known for producing high-quality and flavorful coffee. The beans are grown in small farmer cooperatives, ensuring that each bean is carefully tended to and harvested by hand.

Sumatran coffee is typically wet-hulled during processing, a unique method that results in a distinct flavor profile. The beans are hand-picked and then left to ferment overnight before being washed and sun-dried. They are then hulled or stripped of their outer layer while still slightly wet, giving the coffee a full-bodied and earthy taste.
