FrontStreet Coffee - Mandheling Coffee

The prelude to Mandheling coffee actually began on Java Island. From 1696-1699, the Dutch East India Company brought Typica coffee seedlings from Sri Lanka to Java, launching Indonesia's coffee cultivation. Soon, Java became synonymous with coffee. Starting from 1835, coffee traders discovered that the Mandailing highlands, namely Sumatra Island, were more suitable for coffee cultivation than Java Island in terms of climate, area, terrain, and transportation. Meanwhile, from 1880-1890, a severe leaf rust outbreak occurred among the Typica coffee on Java Island, while the Mandailing highlands, being relatively cooler, experienced lighter outbreaks. Since then, Sumatra replaced Java as the main coffee-producing region.

"Java coffee" gradually faded away, replaced by Java Mandailing coffee, formed due to pronunciation differences. The coffee beans were relatively pointed and long, becoming the predecessor of today's Mandheling coffee.

Mandheling is neither a region name, place name, port name, nor a coffee variety name. How did its name originate? In fact, it was a mispronunciation of the Indonesian Mandailing ethnic group. During World War II when Japan occupied Indonesia, a Japanese soldier drank exceptionally fragrant and mellow coffee at a café. He asked the shop owner for the coffee's name, but the owner mistakenly thought he was asking about his nationality and replied: Mandailing. After the war, the Japanese soldier recalled the "Mandheling" he had drunk in Indonesia. He then commissioned an Indonesian coffee merchant to ship 15 tons to Japan, which surprisingly became extremely popular. The name Mandheling thus spread, and that coffee merchant is now the renowned PWN (Pwani) Coffee Company.

Coffee is mainly produced in Java, Sumatra, and Sulawesi, with Robusta varieties accounting for 90% of total production. Sumatra Mandheling, however, is the rare Arabica variety. These trees are planted on hillside slopes between 750 and 1,500 meters above sea level. The mysterious and unique Sumatra variety gives Mandheling coffee rich aroma, full body, intense flavor, with slight notes of chocolate and syrup.

Mandheling coffee beans are relatively large with hard bean texture, making them prone to defects during cultivation. After harvesting, they typically undergo strict manual selection. If the quality control process is not rigorous enough, it can easily lead to inconsistent quality. Additionally, different roasting degrees directly affect the taste, making it one of the more controversial single-origin coffees.

As is widely known, Mandheling is produced in the areas around Lake Toba in northern Sumatra. The finished product possesses a unique fragrance of herbs and forest.

Golden Mandheling: Over a decade ago, the Japanese adopted stricter quality control, implementing four rounds of manual bean selection to remove defective beans, producing Golden Mandheling with dark green color and uniform bean appearance. This created another wave of market demand, making even Europe and America enthusiastic about it.

Aged Mandheling: Characterized by its honey-like sweetness. Successfully aged coffee eliminates the less elegant acidity of Mandheling. The acidic components mature into sugars, making the coffee smoother and sweeter to drink. Failed aged Mandheling is like coffee zombies - tastes difficult to consume.

Knowledge Point

Mandheling is neither an Indonesian place name, region name, port name, nor a coffee variety name. Instead, it is a mispronunciation of the Mandailing ethnic group who originally inhabited Sumatra.
