Indonesian coffee guide

Every cup of our Master Origin coffee is the perfect balance of coffee craftsmanship, ancient tradition and mother nature. There’s no better example of this than on the coffee farms of Indonesia. Tucked away in the farmlands of northern Sumatra, local coffee growers use a fusion of new and ancient techniques to produce beans unlike any other.

Discover all this and more in our Indonesian coffee guide.


How is our Indonesian coffee harvested?

The hot temperatures and high humidity levels in Sumatra create a unique coffee processing environment for local farmers. Producers have embraced Indonesia’s distinctive climate and, in fact, use it to their advantage through a rare process known as wet hulling.

What is wet hulling

Sumatran farmers race against the rain to wet-hull their coffee in the wet and humid Indonesian climate. Coffee cherries are harvested, pulped, and fermented overnight as normal, but the real Indonesian magic starts once they have been rinsed the following day. Instead of drying the beans, farmers hull them while still wet (at about 40 percent moisture). They remove the parchment when the coffee is soft and moist because exposed beans dry faster.

This uniquely Indonesian approach may have been a process born of necessity as a way to accelerate the drying process in Sumatra's hot, damp environment, but the results are extraordinary.

What does Indonesian coffee taste like?

Our Master Origin Indonesia is unmistakably thick, wildly aromatic, rich in body and is earthen and syrupy with notes of cured tobacco, fruit and tropical perfume.

Indonesian coffee: a sustainable process

Coffee has the power to unite communities, and in some cases, it helps establish them. This has never been so evident, as on the island of Sumatra, where our Master Origin Indonesia wet-hulled arabica was born.

In July 2017, our AAA Sustainable Quality™ Program partnered with Fairtrade to create a new cooperative in Sumatra. It provides members with training and support in relation to sustainable farming practices, how to access affordable supplies and equipment. AAA agronomists are on hand to support farmers and help them to achieve consistent results using the wet-hulling method.

This support means that many farmers have been able to increase production and earn more for their coffee, and we, in turn, have a sustainable source of Master Origin Indonesia Arabica for coffee lovers the world over.

Members of the cooperative call themselves Ara (this is) Cahayani (sun or light) Gayo (the geographic name of the region, the Gayo Highlands). With some 1,800 members farmers, this cooperative is paving the way for Fairtrade coffee and sustainable practices for future generations to come.

Sustainability is at the heart of all of our coffee making. Our AAA Sustainable Quality Program works to source ethical coffee in a sustainable way. It is designed to ensure the continued supply of high-quality coffee, improve the livelihoods of farmers and their communities, and protect the world we live in.
