Coffee Production in Indonesia - Cultivation

Cultivation

Today, more than 90% of Indonesia’s coffee is grown by smallholders on farms averaging one hectare or less. Much of the production is organic and 19 farmers’ cooperatives and exporters are internationally certified to market organic coffee.

There are more than 20 varieties of Coffea arabica being grown commercially in Indonesia. They fall into six main categories:

• Typica – this is the original cultivar introduced by the Dutch. Much of the Typica was lost in the late 1880s, when Coffee Leaf Rust swept through Indonesia. However, both the Bergandal and Sidikalang varieties of Typica can still be found in Sumatra, especially at higher altitudes.

• Hibrido de Timor (HDT) – This variety, which is also called “Tim Tim”, is a natural cross between Arabica and Robusta. This variety originated likely from a single coffee tree planted in 1917-18 or 1926. The HDT was planted in Aceh in 1979.

• Linie S – This is a group of varieties was originally developed in India, from the Bourbon cultivar. The most common are S-288 and S-795, which are found in Lintong, Aceh, Flores and other areas.

• Ethiopian lines - These include Rambung and Abyssinia, which were brought to Java in 1928. Since then, they have been brought to Aceh as well. Another group of Ethiopian varieties found in Sumatra are called “USDA”, after an American project that brought them to Indonesia in the 1950s.

• Caturra cultivars: Caturra is a mutation of Bourbon coffee, which originated in Brazil.

• Catimor lines – This cross between Arabica and Robusta has a reputation for poor flavor. However, there are numerous types of Catimor, including one that farmers have named “Ateng-Jaluk”. On-going research in Aceh has revealed locally adapted Catimor varieties with excellent cup characteristics.
