Sumatra Specialty Coffee region: A Representative of Indonesia

The history of the Sumatra Specialty Coffee region dates back to the early 17th century when the Dutch East India Company (Vereenigde Oost-Indische Compagnie) introduced coffee varieties to the colonies. The Dutch colonists began cultivating Typica and Bourbon varieties in North Sumatra, particularly in Aceh, to meet the growing demand in Europe for this novel beverage. Thanks to the unique climate and soil of the Sumatra region, coffee quickly became one of the area’s key products.

Over the centuries, Sumatra has not only maintained but also robustly developed its coffee cultivation tradition. Today, Indonesia ranks as the third-largest coffee producer in the world, with Sumatra playing a crucial role in the country’s Specialty coffee community. The region is home to approximately 40,000 coffee-growing households, each typically owning less than 2 hectares of land. Coffee cultivation here is not conducted on a large scale but is carried out by small family groups, each consisting of 60 to 130 farmers. These groups often collaborate, forming cooperatives and operating under the management of a supervisor. The supervisor is responsible for collecting coffee and transporting it to local exporters, ensuring that Sumatra’s coffee reaches the international market.

Sumatra has about 40,000 coffee farming households, each typically owning less than 2 hectares of land.

Each prominent coffee-producing area in Sumatra has its own unique flavor profile:

• Mandheling

Mandheling is located in the central-western part of Sumatra, near Padang. The mountainous terrain and fertile land, coupled with abundant rainfall throughout the year, create an ideal environment for Arabica coffee cultivation. Thanks to these natural conditions, Mandheling coffee has a smooth, thick texture often described as syrupy, with a mild acidity that balances the sweet chocolate flavors and earthy tones.

• Lintong

Another coffee-growing area, Lintong, is situated in northern Sumatra, near Lake Toba—the largest volcanic lake in the world. With an ideal elevation of over 1,200 meters above sea level, a cool climate year-round, and nutrient-rich volcanic soil, Lintong provides excellent conditions for coffee growth. Lintong coffee has a light sweetness, low acidity, and a characteristic earthy and cedar aroma, offering a complex flavor that is hard to find elsewhere.

• Aceh

Aceh, located in the northernmost part of Sumatra, is a highland region with a temperate climate and ample rainfall, making it very suitable for coffee cultivation. Aceh is renowned for its long-aged coffees that develop additional flavors, creating unique experiences for drinkers. Coffee from this area has a complex flavor profile, sometimes quite distinct from other Sumatra coffees, and is highly valued by those who appreciate diversity and rarity.

• Gayo

Gayo is the largest coffee-growing region in Sumatra, located on the Gayo Plateau surrounding Mount Gayo and Lake Tawar, with elevations ranging from 1,300 to 1,600 meters. The cool climate and ideal altitude help the coffee thrive, producing its distinctive flavors. Gayo coffee is notable for its rich spice flavors, such as clove and cardamom, along with low acidity, making it one of the most sought-after premium coffees.

Unlike many other coffees that are fully washed, most Arabica coffee from Sumatra undergoes wet hulling, a distinctive method that preserves the unique characteristics of the beans.

The process begins with crushing ripe coffee cherries, then allowing them to dry to about 35% moisture before hulling them while the beans are still soft and wet. However, this hulling process can lead to many beans being flattened and losing their perfect shape. Nevertheless, the value of the beans remains intact. On the contrary, this impact contributes to the distinctive flavor profile of Sumatra coffee.

After hulling, the coffee is dried on patios for several days. Some processors use a method of piling coffee at night and covering it with tarps to retain heat and enhance the wild flavors. Finally, to achieve the best quality before export, the coffee is dried to a moisture content of 12 to 14%, whereas other Specialty coffee regions typically require a moisture content of 10 to 12%. This flexibility in the drying process not only ensures that the coffee retains its best quality but also helps producers optimize the unique flavor characteristics of Sumatra Specialty coffee.
