Our Indonesia Range

Our range from Indonesia includes only the best quality coffee for both blending and single origin preparation. We source primarily from Sumatra, Sulawesi and Java, with both Estate and Community coffees available. Talk to us about your Indonesia needs, as we can also source on demand for special requirements.

One of our staple coffees, Aceh Gr 1 is clean and herbal with plenty of body and a crisp acidity. The process is Giling Basah, or wet hulling, whereby the parchment is removed from the beans shortly after pulping, and the green coffee is then sundried prior to sorting and grading. This process moderates the naturally high acidity of the region and improves the body, giving a unique Sumatran character.

Created at our own Wahana Estate, this is a wet-hulled coffee produced from the best select cherries.  A rich, clean coffee with mild herbal and chocolate notes, Sidikalang Gold is slightly milder than the Aceh type, but exhibits a very rich, creamy body when made for espresso.

Sulawesi coffee has a flavour and character all it’s own. If you are looking for the buttery body and clear acidity without the herbal or peppery flavours from Sumatra or Java, Sulawesi is ideal.  Chocolate and caramels predominate, with a famously huge body and lovely mild acidity.

From the Government Estates of Eastern Java comes this longstanding pillar of Indonesian coffee.  Ever reliable from year to year, this fully washed coffee offers a very clean cup with notes of chocolate, mild spice and black pepper.  The rich, red crema obtained through espresso makes this an excellent addition to premium blends.

Indonesian History

Indonesia is a fascinating country composed of around 17,500 islands, of which about 7000 remain uninhabited. It sits astride the junction of three major land masses, the Asian Sunda Shelf, the Australian Sahul Shelf and the extended mountain chain of Japan and the Philippines. The equator also passes through Sumatra, Kalimantan and Sulawesi, giving Indonesia a climate which is maritime and tropical, encompassing active volcanoes, thick rainforest and sea level swamps. 

The unique geographical position of the archipelago has made it a hub of East-West trade for almost 2000 years. Indonesia has traded timber, spices and resins with India, China and the Middle East for centuries, gradually incorporating Hinduism, Buddhism and Islam while retaining regional self governance and culture.  This changed with the arrival of the Dutch in the 17th century.  The Dutch, via the Dutch East India Trading Company, gradually became the dominant power in the islands, eventually excluding both the Portuguese and the British, finally bringing military force to bear against the Indonesian kingdoms themselves to take governmental control of the major islands. The interest was purely to obtain monopolies of trade over desired commodities such as coffee, pepper, cloves and timber. The Company was able to dictate which areas would grow each commodity, and set compulsory quotas on the populations to be delivered in tribute each year.  While clearly exploitative, like many colonial experiences, the period was not wholly negative, and feelings towards the Dutch in Indonesia today are quite benign; indeed many Indonesians have migrated to the Netherlands to form a substantial community.

During the Second World War, the Islands were occupied by the Japanese, who were at first hailed as liberators by nationalists. This feeling was not to last, as the Japanese viewed Indonesia simply as a source of war materials and southern base of operations.  Following the defeat of Japan, the Dutch expected to regain full control of the archipelago, but encountered strong resistance from Indonesia and the international community.  After several years of negotiations and attempts to regain governance by force, the Netherlands eventually agreed to release sovereignty of the Islands to Indonesia in 1949, with the exception of West Papua, which would remain in Dutch hands until 1962.

Following Independence were many years or turbulence, authoritarianism and corruption as Indonesia struggled to re-build the nation from two centuries of colonial rule. Despite the difficulties of governing a vast and culturally diverse country spanning a geographically separated island group, Indonesia continues to improve socially and economically, although as in most nations, human rights struggles continue to present challenges.

Coffee History in Indonesia

Coffee was brought to Indonesia by the Dutch around 1699, with the intention of breaking the  Arabian monopoly of coffee, then being exported from the Port of Muhka in Yemen.  After a difficult start, coffee began to be cultivated around Batavia (now Jakarta), and during the 1700’s spread to Sumatra, Bali, Sulawesi and Timor.  

In 1876 disaster struck the industry in the form of coffee rust (Hemileia vastatrix), a fungal infection which thrives in warm conditions following rain.  This attacks the leaves of the plant, causing extensive defoliation. Rust is a fungus dedicated to the coffee plant for survival, and probably originated in Ethiopia. While it is rarely a significant problem in that country, both Indonesia and Ceylon, the world’s largest producers of coffee in the late 1800’s, suffered devastating losses to the crop. As a result arabica coffee was annihilated in both countries.  This may well have resulted from the poor genetic diversity of the coffee crop, having been propagated from only a tiny sampling of trees growing in Imperial gardens.  To further the problem, no existing pesticides were capable of controlling the fungus.

Following the loss of the arabica crop, robusta (Coffea canephora) was introduced to Indonesia, after a brief and unsuccessful experiment with Coffea liberica.  Robusta coffee thrived in the country, and for many years was a significant export.  Through the early 1900’s coffee spread across the islands again, being planted around Lake Toba in 1888, and Gayo in 1924.  

In 1949 after Independence, the government nationalised the old colonial estates of the Javanese Ijen Plateau. Arabica coffee was planted successfully, and eventually was dispensed to small holders, making Indonesia an arabica producing nation once more after nearly 80 years.  While robusta of surprisingly good quality continues to be produced at Governments Estates such as Kaselogiri, the focus is on the five main arabica producing Estates: Jampit, Blawan, Pancoer, Kayumas and Tugosari.  

Today, quality arabica coffee is once again produced across Indonesia, with the largest production from Sumatra and Java. Smaller amounts of high quality coffee are produced in Sulawesi, Bali, Flores and West Papua.
