What Is Mandheling Coffee?

Mandheling coffee comes from the mysterious island of Sumatra, in Indonesia—the largest coffee-producing country in all of Asia. Unlike most coffees, Mandheling's name is tied to a long-circulated story, mainly originating from a mispronunciation of a local indigenous ethnic group in Indonesia.

During World War II, a Japanese soldier was drinking coffee at a shop in central Indonesia and asked the owner what kind of coffee he was drinking. The owner thought he was asking where he was from, so he answered "Mandailing" (the Mandailing people). After the war, when the soldier returned home, he recalled that the coffee with the distinctive taste seemed to be called "Mandheling." In 1968, the Nomura Trading Company of Osaka, Japan, visited the Indonesian company N.V. Pawani Medan and imported 15,000 kilograms of SumatraMandheling coffee, which became hugely popular after being released on the Japanese market. From then on, both Mandheling coffee and the Pwani Coffee Company became widely famous.

Sumatra is divided into eight provinces in total, yet only Aceh in the north and North Sumatra grow coffee on a large scale. As the world's largest and deepest volcanic lake, the scenic Lake Toba provides mineral-rich soil for Lintong Mandheling coffee. Most of the coffee trees grow on higher-altitude slopes, covered by several kinds of ferns that provide good sun protection for the coffee, so growers do not need to use shade cultivation.

Why Mandheling Has a Unique Flavor

Sumatra lies near the equator and has an island-type tropical rainforest climate, with humidity in the air as high as 70–90%. This hot, humid environment easily causes green coffee beans to mold during fermentation or drying. So local coffee farmers adapted to local conditions and developed a semi-washed processing method—wet hulling. Wet hulling means "forcibly" hulling off the parchment layer while it is still not completely dry, so the green beans complete their final drying in a "naked" state.

Wet hulling begins to differ from the traditional washed method starting at fermentation: wet hulling uses less water for fermentation and has a shorter fermentation time. After this brief fermentation, a small amount of mucilage still remains on the bean hull. When the green beans reach 35/40% moisture content after the first drying, the coffee farmers sell the beans to collectors. The collectors directly hull the semi-dry, hull-on beans they purchase, removing the mucilage and bean hull to obtain green beans. Although the time required for each step is greatly shortened, the "naked beans" still absorb moisture from the hot, humid air, so the resulting Mandheling coffee gains more of a deep, muted aroma of wood, herbs, and spices.

Indonesian Coffee Grades

The grading of Indonesian green beans is based primarily on the number of defective beans, with size as a secondary criterion. At coffee origins, beans are generally sorted with a bean sorting machine to prevent impurities and defective beans from being mixed in. However, Mandheling green beans are relatively large and hard in texture, and defects can appear during cultivation, harvesting, and processing, so using only a sorting machine makes it very difficult to completely remove defects. To reach a higher grade, the coffee must undergo strict hand sorting. Local green beans are divided into six grades according to defect rate. The highest grade, G1, requires that a 300g sample contain fewer than 11 total defective beans. Front Street's Lintong Mandheling is hand-sorted G1 grade.

Speaking of hand sorting, one must mention a premium selection that has undergone layer upon layer of screening—Front Street PWNGolden Mandheling Coffee.

When producing coffee, PWN gives the Mandheling green beans it purchases one machine sorting plus three hand sortings, ensuring that every green bean is intact, uniform, plump, and must reach a size of 18 mesh or above—that is, Indonesia's local G1 grade. Unlike other Mandheling coffees, after rigorous selection Front StreetGolden Mandhelingcoffee eliminates the earthy and woody flavors typical of ordinary Mandheling, giving it a cleaner taste and a clearer, more transparent finish.

How to Bring Out Mandheling Coffee's Unique Flavor?

As mentioned above, Sumatra's environment and soil give the coffee a rich herbal character along with the sweetness of cocoa and fruit. The classic Mandheling flavor is known for its full-bodied dark chocolate notes, and it is suitable for a medium-dark roast to present a rich, full-bodied taste while retaining the aroma of herbs and plants.

, what remains is how to brew it to showcase Mandheling's distinctive aroma. There are countless ways to brew coffee, and there is no standard answer. In fact, as long as it can present the flavors the coffee should have, simply put: as long as it tastes good. For Front Street PWNGolden Mandhelingcoffee, you can use a three-pour pour-over method for extraction if you hope to drink a Mandheling flavor with more layering.

When Front Street brews deep-roasted coffee beans, it uses a slightly coarser grind and a lower water temperature than for light-roasted beans, in order to avoid releasing too many bitter large molecules and making the coffee taste only burnt and bitter. The Kono dripper is chosen to enhance the coffee's round, full-bodied mouthfeel. The upper part of the Kono is a smooth curved surface, which allows the filter paper to fit more closely, restricts airflow upward, and lets hot water only flow downward, creating a siphon-like extraction effect that allows the coffee powder's aromatic substances to be released more fully.

Dripper: KONO dripper

Water temperature: 87–88°C

Coffee dose: 15g

Coffee-to-water ratio: 1:15

Grind size: medium grind (70% pass-through rate on Chinese standard No. 20 sieve)

Use twice the amount of water as coffee powder to wet the coffee bed, forming a dome and letting it bloom for 30s. Then, with a small stream, pour in a circular motion from the inside out until 125g, then pause. When the coffee bed drops to half the height of the dripper, continue pouring the third stage with the same fine stream until 225g. Once all the coffee liquid has filtered through, remove the dripper. The total time is about 2 minutes.

The hand-brewed Front Street PWN Golden Mandheling coffee has intense aromas of dark chocolate, nuts, and caramel, with a finish of spices and herbs. The mouthfeel is clean and transparent, full and solid, with distinct layers.
