Asia is the largest and most populous continent among the seven continents, with varied terrain featuring high elevations in the center and lower elevations at the periphery. Mountains, plateaus, and hills account for three-fourths of the total area. Additionally, the Asian continent spans across cold, temperate, and tropical zones, with complex and diverse climate types. It can be said that many Asian countries are suitable for coffee cultivation, including Indonesia, known as the "country of ten thousand islands."

In the 17th century, the Dutch colonial government planted the first coffee trees near Batavia (now Jakarta) in Indonesia. Although these seedlings were destroyed in a flood, the second batch of seedlings successfully bore fruit and thrived in the region.

By the early 18th century, ships from the Dutch East India Company exported the first batch of coffee from the port of Java to Europe. After that, the Indonesian government exported thousands of pounds of coffee annually. At that time, Indonesia only cultivated Arabica varieties. However, in the 1860s, Coffee Leaf Rust (CLR) destroyed most of Indonesia's coffee crops. Consequently, most farmers began to switch to Robusta, which is more disease-resistant and easier to grow, replacing Arabica trees. Today, Robusta coffee accounts for 85% of Indonesia's total production, while Arabica accounts for 15%.

Indonesia's Natural Advantages

As the world's fourth-largest coffee-producing country, Indonesia's high production volume is attributed to its rich natural resources. Unlike other coffee-producing countries, this Southeast Asian nation consists of 17,508 islands, making it the world's largest archipelagic country, spanning both Asia and Oceania. Indonesia straddles the equator and has a tropical rainforest climate with warm and humid weather throughout the year. Average temperatures range between 25°C-27°C, and the year is divided into dry and wet seasons due to monsoons.

As a country with numerous volcanoes, Indonesia has more than 500 volcanoes across its territory, along with many rivers, lakes, and forests. With a forest coverage rate of 67.8%, it provides ideal conditions for coffee cultivation. Currently, several islands in Indonesia grow coffee trees, with production regions divided by island, such as Sulawesi, Bali, Java, and Sumatra.

Sumatra Island

Sumatra: Indonesia's Premier Coffee Region

Among these, Sumatra Island is Indonesia's largest and highest coffee-producing island, featuring a tropical rainforest climate with consistently high temperatures and humidity throughout the year. Coffee trees are typically grown in mountain forests. The coffee produced from Gayo Mountain in the Aceh region can be considered the highest quality in the entire Sumatra region. Most of these are ancient varieties grown at high altitudes between 1,500-2,500 meters.

Additionally, the Lintong region, which also produces Mandheling coffee, enjoys considerable fame. The Lintong region is located beside Lake Toba in Sumatra, with cultivation altitudes between 1,400-1,800 meters. Although the coffee beans from here are not as high-quality as those from Gayo Mountain, due to the local unique wet-hulling processing method, the coffee features low acidity and a rich, full-bodied mouthfeel. FrontStreet Coffee considers Lintong Mandheling as the basic version of Mandheling coffee, which is why FrontStreet Coffee introduced Indonesian daily-use beans by selecting Mandheling coffee from the Lintong region. This allows everyone to experience the regional flavor characteristics at the most affordable price.

Java: Indonesia's Historic Coffee Region

Java Island, located south of the equator, is the fifth-largest island in Indonesia. The island has an overall elongated shape with terrain dominated by mountains and hills. Between the mountains are vast basins with numerous rivers and over 100 volcanoes. Therefore, the island's soil is fertile with excellent natural conditions, and it remains a developed agricultural zone with 70% of its land used for cultivation. This island was also the earliest region in the country to cultivate coffee.

The entire island is composed of West Java, Central Java, East Java, and the special regions of the old capital Jakarta (which relocated to the new capital Nusantara in 2024) and Yogyakarta. Coffee cultivation is distributed throughout the island, grown in the Preanger region of West Java; in Central Java, it's cultivated in Banjar Negara, Wonosobo, and Temanggung, all three areas surrounding Merapi Volcano; and in East Java, which is the largest and most important production area on the island, coffee is grown around the Bromo and Ijen volcanoes.

Cultivation altitudes range between 900-1,800 meters, where many varieties are grown, such as Typica, Tim Tim, Ateng (local name), and USDA 762.
