Indonesia is one of the world’s largest coffee producers, famous for its diverse islands and unique processing methods. Among its many regions, Sumatra and Java stand out as icons of Indonesian coffee culture.
The History of Indonesian Coffee Culture
Coffee was introduced to Indonesia in the late 1600s by Dutch colonizers, who recognized the fertile volcanic soils of Java as ideal for cultivation. By the early 1700s, large plantations were established, and Java quickly became synonymous with coffee worldwide.
- 17th Century: Arabica seeds from Yemen were planted in Java under Dutch East India Company control.
- 18th Century: Java coffee gained fame for its rich, full‑bodied flavor, exported across Europe.
- 19th Century: Coffee spread to Sumatra, Sulawesi, and other islands, diversifying Indonesia’s production.
- 20th Century: Robusta became dominant after leaf rust disease devastated Arabica crops.
Indonesian coffee culture reflects both colonial history and local adaptation. Coffeehouses in cities like Jakarta and Yogyakarta now blend modern café trends with traditional brewing, keeping the heritage alive.
How Indonesian Coffee Is Processed (Giling Basah Method)
One of the most distinctive aspects of Indonesian coffee is its unique wet‑hulling process, locally known as giling basah. In this method, farmers hull the beans while they are still wet — at around 30–40% moisture — instead of waiting until they are fully dried.
- Step 1: Coffee cherries are pulped to remove skin.
- Step 2: Beans are partially fermented and dried to about 30–40% moisture.
- Step 3: The parchment layer is hulled while still wet (unlike fully washed methods).
- Step 4: Beans are dried again to 12–13% moisture before export.
Advantages:
- Faster drying in humid regions.
- Produces distinctive earthy, herbal flavors.
- Creates the heavy body associated with Sumatra coffee.
Limitations:
- Less consistency compared to fully washed methods.
- Can introduce variability in flavor.
This method is a defining feature of Indonesian coffee, giving it a taste profile unlike any other origin.
