Indonesia Coffee Buying Made Simple

Coffee regions in Sumatra

No one needs convincing about the appeal of Indonesia’s coffees—or of how synonymous this origin is with coffee. (Java, anyone?) But in case you could use a little help selecting between its extensive offerings, we’ve put together some quick island summaries and coffee one-liners.

Our Indonesia offerings represent regions, farms and individuals. And from the country celebrated for giling basah (or, wet hulled, in the Bahasa language), we even have a honey-processed option. Three things all these coffees do have in common, though, is that they were carefully processed by trusted partners, are fully traceable and are fantastic values. And of course, they're all delicious!

We hope you're encouraged to learn more about Indonesia—and to find the cup that's right for you.


Sumatra is the second largest of Indonesia's more than 17,000 islands.

Sumatra map

Its best-known coffee areas include Aceh, its most northern region; Lake Toba, farther south in the North Sumatra region and below the capital city of Medan; Batak, in northwestern Sumatra, near the shores of Lake Toba; Lintong, at the southwestern edge of Lake Toba; and Kerinci, at the southern border of the West Sumatra region. (Mount Kerinci, the focal point of Kerinci, is the highest of Indonesia’s 400 or so volcanoes.)

In Aceh, the Leuser mountains — said to host one of the world’s richest and most ancient ecosystems — run from the Gayo highlands, down and south through Batak. Mandheling coffees (named after the Mandailing people, but spelled differently) are grown on the slopes of Mount Leuser, in soil that’s mineral-rich from volcanic ash.

The classic “Sumatra” cup profile—earthy, fruity, herbal and creamy—is the result of Giling Basah, a processing method specific to Indonesia. Coffee is dried to 50 percent (versus the more common 10 or 12 percent) and then hulled and bagged and stored to rest. Elsewhere, hulling typically happens after the coffee has rested and just before it’s sent to the port.

Java is Indonesia’s fifth-largest island. It's dotted with volcanos and home to more than half of the entire country’s population. Java also has a few large estates that were established under Dutch colonial rule. They're optimally situated high on the Ijen Plateau and today are state run. (The Jampit Estate, for example, hosts programs that focus on plant healing and business benchmarking, and includes a cupping room, strawberry farm and guest house.)

Most coffee on Java is grown on its eastern end, around the Ijen volcano, and is harvested between July and September. More recently, Arabica has been planted in West and Central Java, and production is increasing each year.

Sulawesi has four long peninsulas that radiate from its mountainous center. Most Arabica is grown around Tana Toraja, home of the Toraja people (who are fabled to be the descendants of divine beings who arrived on this outrageously gorgeous island via a stairway from heaven). Toraja communities are instantly recognizable by their distinctive peaked-roof houses (tongkonan) and wood carvings.
