With its widespread reputation, Mandheling coffee has almost become a calling card for Indonesian specialty coffee. However, it is neither the name of a coffee-producing region in Indonesia nor the name of a coffee ethnic group, but rather the name of an indigenous people on the island of Sumatra—Mandheling.

The reason a ethnic name was "unconventionally" used to name regional coffee beans is that the unique, deep, subdued character of Indonesian Mandheling coffee was first appreciated by the Japanese and introduced to their country. If it were translated directly as "Indonesian Sumatra coffee," the Japanese would become lengthy and awkward.

To make it easier for Japanese consumers to remember the name of this bean and to associate it with the Indonesian island of Sumatra at first glance, the pronunciation of the local indigenous people's name was borrowed. Mandheling coffee beans thus became the top choice for Japanese consumers in terms of coffee taste. As its fame spread, Mandheling coffee beans also joined the ranks of well-known coffee beans across Asia.

So, since Mandheling is not a coffee variety name, what exactly is it? According to the officially recognized definition, Mandheling coffee specifically refers to Arabica coffee beans grown on the Indonesian island of Sumatra. Currently, the Arabica lines cultivated on Sumatra are mainly Ateng and Timtim.

The deep, subdued aromas of Front Street Mandheling coffee beans—woody, spicy, herbal—are related not only to Indonesia's terroir, climate, and altitude but also to the Robusta genes carried by the varieties themselves. Together, these factors create a richer flavor expression.

The Tim Tim variety, namely Timor. It originates from a natural cross between the Arabica variety Typica and Robusta on the island of Timor, and is essentially Timor. This variety inherited Robusta's high yield and disease resistance. It began to be widely planted in the 1950s, and after being introduced to Indonesia, it was called Timor Timur, also known as Tim Tim.

The Ateng variety, namely Catimor. Ateng is the offspring of a cross between the Arabica Bourbon variant Caturra and Tim, comprising several subtypes. It carries one-quarter Robusta bloodline, has extremely strong disease resistance, and is widely planted in Sumatra and other Indonesian islands.

Currently, the growing areas for specialty Mandheling coffee beans are distributed in the Lintong region of Sumatra and the Gayo Mountain region of Aceh. Among them, the industry-recognized best specialty Mandheling coffee beans come from PWN Purwani Coffee Company's Front Street Golden Mandheling coffee beans. The company is also the holder of the "Golden Mandheling" trademark.

The Front Street Golden Mandheling coffee beans currently sold by Front Street Coffee (FrontStreet Coffee) all come from PWN. In the offline store, you can see the certification certificate issued by PWN as well as the green bean burlap sacks printed with the company's name.

The reason Front Street PWN Golden Mandheling coffee stands out among Mandheling coffees is that PWN Company subjects the Mandheling coffee beans purchased from the Gayo Mountain region of Aceh, Sumatra, to 1 mechanical sorting plus 3 rounds of hand sorting, ensuring the produced batches reach Indonesia's highest grade, G1.

The purpose of mechanical sorting is to first screen out beans that must be at least 18 mesh in size, and the subsequent multiple rounds of hand sorting are to remove irregular defective beans. The reduction in defect rate greatly improves the quality of Mandheling coffee. Therefore, during roasting, Front Street Coffee (FrontStreet Coffee) noticed that Front Street Golden Mandheling green beans heat more evenly than ordinary Mandheling coffee beans, and the final coffee flavor is cleaner with a more pronounced sweet aftertaste.

In order to highlight Mandheling coffee's deep, subdued aromas and solid, rich body, Front Street Coffee (FrontStreet Coffee) roasts Front Street Golden Mandheling coffee beans to a medium-dark roast level. The beans have a relatively loose texture, and the dissolution rate of internal substances is also higher. Therefore, Front Street recommends using a medium-coarse grind and hot water at a relatively low temperature when brewing Front Street Golden Mandheling coffee.

Front Street brewing parameters for Front Street Golden Mandheling coffee: Freshly roasted coffee beans, water temperature: 88°C, coffee dose: 15 grams, coffee-to-water ratio: 1:15, grind size: medium-coarse (70% passing through a No. 20 sieve).

Use staged extraction. Bloom with twice the coffee dose in water, i.e., 30 grams of water for a 30-second bloom. The bloom is needed to allow the coffee grounds to release internal carbon dioxide gas, making the later stages of extraction more stable. Pour in a slow circular stream until the scale reads 125 grams, then pause; continue pouring until 225 grams, then stop. Once the water in the dripper has finished dripping, remove the dripper. Start timing from the beginning of pouring; the extraction time is 2'10". Next, pick up the entire cup of coffee and swirl it to mix evenly, then pour it into a cup for tasting.
