Indonesia Growing Region

The Tana Toraja mountainous region in South Sulawesi, Indonesia, located at an altitude of 1,700 meters, features high-altitude volcanic terrain with abundant sunshine and significant day-night temperature differences, maintaining temperatures between 24°C~25°C. Because it possesses fertile volcanic weakly acidic soil of tropical highlands, it cultivates high-quality Arabica beans.

Toraja coffee beans have a very similar appearance to Mandheling coffee from Sumatra, with full, plump beans. They are processed using Indonesia's traditional Natural Process/Semi-washed method. The finest Toraja coffee beans come from the Kalosi estate, with an annual production of only 3,000 barrels. Each barrel has a code, and every wooden barrel containing coffee beans is hand-carved and painted, making them unique crafts in the world, extremely precious.

This coffee has rich and intense aroma, with low acidity and a fresh earthy flavor, and a long-lasting aftertaste that challenges the palates of coffee connoisseurs. Therefore, this coffee is world-famous and has become a gift "tribute" when the Indonesian government hosts the European Union.

Indonesia is the world's largest archipelagic country. As early as the 18th century during Dutch rule, Arabica coffee trees were introduced for cultivation. The main growing regions are located on Sumatra, Java, and Sulawesi islands. The produced Mandheling has a deep, low-acidity, full-bodied taste, leading people to call it 'the world's most important coffee.' It is also the world's fourth-largest producer with an annual output of 7 million bags. Coffee is harvested twice a year,分别在 May~June and September~October, with the largest production from Sumatra and Aceh provinces. Coffee farm sizes are small, typically around 1~3 hectares.

Indonesian Mandheling coffee processing generally uses the semi-washed method. Coffee farmers remove the external peel and pulp of harvested mature coffee beans but retain the membrane tissue on the beans. Through a water soaking fermentation process, unfirm beans that float on the water surface are removed, while firm, sinking quality beans with surface membrane are sun-dried (either elevated or directly on the ground). Finally, dryers are used to achieve uniform moisture content standards. The most unique aspect is wrapping coffee beans with parchment paper and membrane to maintain 18% moisture content. Before shipment, the membrane on the coffee bean surface is polished and cleaned. People call this special processing method the Indonesian semi-washed method. Large coffee processing factories can precisely control each processing step, maintaining consistent flavor and quality levels. Small coffee farmers process raw beans in their own yards, and flavors vary depending on each farmer's processing methods and skills, developing varying degrees of good and bad flavors.

Coffee produced on Indonesia's third-largest island, Sulawesi, amounts to about 70,000-80,000 bags annually, accounting for only 9% of Indonesia's total coffee production. Coffee grows in rainforests at altitudes of 750~1,500 meters. High-quality coffee is mostly planted around the Toraja highlands in the southwestern region. Toraja is located at 1,500 meters above sea level on the equatorial belt, with year-round afternoon rain and mist, plus fertile volcanic soil - these are the best natural climate and environment for coffee growth.

Most Indonesian coffee is handled by local coffee companies responsible for trading and export sales. Direct to coffee, the small-scale Binalestari coffee merchant in the Sulawesi Toraja region introduces coffee. The coffee is Arabica species grade G1, with raw coffee beans showing a long rice shape and beautiful emerald green color, different from the yellowish-brown of Gold Mandheling and Sumatra Mandheling (photos are available for comparison on the blog). Moreover, there are few defective beans and poorly fermented white beans, making it a good coffee from small estates with less distracting earthy smell.
