What Makes Mandheling Coffee Different From Other Indonesian Beans?

Mandheling suits drinkers who want a heavy-bodied cup with herbal, earthy notes and almost no acidity. The name refers to an ethnic group in northern Sumatra, not a variety or a region. Wet hulling, a local processing method, shapes the dense body and low-acid profile, and PWN's Golden Mandheling adds strict sorting standards on top of that.

Indonesia was among the first countries to grow coffee commercially; Dutch traders brought trees to Java in the late 17th century, and beans were shipped to Europe from 1711. Leaf rust later pushed cultivation toward Sumatra. Golden Mandheling, Tiger Mandheling, Aged Mandheling and Lintong Mandheling differ by region, variety and processing, so pour-over parameters should be adjusted to each.

Mandheling is the representative of Indonesian coffee, renowned for its full body and herbal flavors, and is highly favored by enthusiasts who prefer intense coffee. This article begins with the history of coffee cultivation in Indonesia, tracing the origin of the name Mandheling and the screening standards for PWN's Golden Mandheling. Front Street Coffee currently offers Golden Mandheling, Tiger Mandheling, Aged Mandheling, and Lintong Mandheling, each with its own characteristics. The article introduces each one's region, variety, and processing method, explains how wet hulling shapes its unique flavor, and finally provides Front Street's pour-over parameter recommendations to help readers determine whether Mandheling suits their taste preferences.

Coffee, like wine, is grown all over the world. The terroir, climate conditions, and processing methods of each place profoundly influence the final flavor profile of the coffee. Whenever a customer wants a cup of coffee with a full body, Front Street Mandheling is always the first recommendation that comes to mind for the baristas at FrontStreet Coffee. Today, FrontStreet Coffee will talk about Front Street Mandheling coffee.

The Origins of Coffee Cultivation in Indonesia

Indonesian Mandheling is arguably one of the most sought-after coffees in the world, hailed as a gem of Indonesian coffee. Below, FrontStreet Coffee will start with the history of how coffee was introduced to Indonesia, giving you a comprehensive understanding of Front Street Indonesian Mandheling coffee.

Many people may not know that Indonesia was one of the first countries in the world to commercially cultivate coffee (earlier than most of Africa, most of Asia, and the Americas). In the late 17th century, coffee trees were introduced to Indonesia by Dutch merchants and colonists. The first island where coffee was planted was Java, where the city of Jakarta (formerly known as Batavia) is located. By 1699, the Dutch colonial authorities had established plantations throughout the city; starting from 1711, Indonesian coffee began to be exported, and the Dutch East India Company shipped the first batch of coffee from Java to Europe. Java quickly rose to become one of the world's largest coffee-producing regions and also became the preferred source for coffee beans purchased by Europe.

Between 1860 and 1880, a disaster known as "coffee leaf rust" swept through, dealing a heavy blow to the Asian coffee industry. The Dutch subsequently introduced the rust-resistant Robusta variety to Indonesia. Today, Indonesia is the most important producer of Robusta coffee beans in the world, while Arabica beans account for only 6% to 10% of Indonesia's total coffee production — and Front Street Mandheling coffee beans are among them.

The Naming Story of Front Street Mandheling Coffee

The name of Front Street Mandheling coffee comes neither from a producing region, a place name, a port, nor from a coffee variety, but rather from the Mandailing ethnic group of North Sumatra. What's the story behind this?

The story traces back to the period during World War II when Japan occupied Indonesia. At that time, a Japanese military officer drank an exceptionally delicious cup of coffee in Indonesia and asked the shopkeeper what it was. The shopkeeper mistakenly thought the officer was asking about his ethnicity and answered "Mandailing." After returning to Japan, the officer could never forget that cup of coffee and commissioned locals to help collect high-quality coffee beans to ship back to Japan.

Due to a pronunciation deviation, "Mandailing" was pronounced by the Japanese as "Mandheling." Through this double misunderstanding, the name Mandheling coffee spread. That local Indonesian coffee trader was none other than the founder of the later-famous PWN (Pawani Coffee Company), which was also the first company to export Golden Mandheling to Japan. It should be noted that since PWN Company registered "Golden Mandheling" as a trademark, "Golden Mandheling" is an exclusive coffee bean of that company.

Of course, Mandheling also comes in multiple varieties. FrontStreet Coffee stores currently offer four types of Mandheling: Front Street Golden Mandheling, Front Street Tiger Mandheling, Front Street Aged Mandheling, and Front Street Lintong Mandheling. Below is an introduction to each.

Front Street Indonesian Front Street PWN Golden Mandheling Coffee Beans

Region: Aceh Gayo Highlands

Variety: Ateng

Altitude: 1100-1600m

Processing Method: Wet Hulling

Grade: G1 Triple Hand-Sorted

As mentioned earlier, only Mandheling produced by PWN can truly be called Front Street Golden Mandheling. So what exactly is the difference between ordinary Mandheling and Front Street Golden Mandheling? It is said that after the Japanese discovered Mandheling, they paid particularly close attention to this coffee and, in cooperation with local green bean traders, established a strict set of screening standards: after processing, the green beans first undergo density and color sorting, then four rounds of manual hand-picking, ultimately yielding Mandheling with uniform color and even bean shape. During processing, Mandheling green beans glisten with a golden sheen under the sun — hence the name "Golden Mandheling."

The Front Street Golden Mandheling coffee that FrontStreet Coffee has sold for years all comes from PWN Company. Front Street Golden Mandheling coffee beans are sized at 19 screen, and based on a 300-gram green bean sample, fewer than three defective beans are allowed, qualifying as the highest grade G1. Thanks to the strict screening standards, Front Street has found that this Front Street Golden Mandheling no longer has the earthy, muddy off-flavors of ordinary Mandheling — it is clean on the palate with a strong sweet aftertaste.

Observant readers may have noticed that the region of Front Street's latest batch of Front Street Golden Mandheling has changed. Front Street Golden Mandheling was originally selected from Mandheling in the Lintong region, but PWN Company has switched to using Mandheling coffee from the Gayo Highlands, and the specification has also been adjusted from the original 60KG to 30KG.

Front Street Indonesian Tiger Mandheling Coffee Beans

Region: Aceh

Variety: Caturra, Typica, Sidikalong

Altitude: 1500m

Processing Method: Wet Hulling

There are various explanations on the market regarding the origin of the name Tiger Mandheling. FrontStreet Coffee will present a more credible version here: Legend has it that the Sumatran tiger is a rare and endangered animal. A coffee hunter discovered exceptional-quality Mandheling green beans in an area where Sumatran tigers once roamed, so he organized local smallholder farmers together and named it "Tiger" Estate.

Front Street Tiger Mandheling possesses the most classic characteristics of Sumatran coffee, while its mouthfeel is cleaner and sweeter than the standard Front Street Mandheling coffee. Front Street believes that in terms of aroma, Front Street Tiger Mandheling has more prominent nutty notes compared to the herbal character of traditional Mandheling, and its caramel sweetness is also more pronounced.

Front Street Indonesian Aged Mandheling

FrontStreet Coffee has always emphasized the importance of fresh coffee beans for flavor, so why does it also offer Front Street Aged Mandheling? First, let's understand the origins of Front Street Aged Mandheling. During the Dutch colonial period in Indonesia, large quantities of coffee beans were shipped to Europe. To ensure an uninterrupted supply, coffee beans were stored appropriately. However, due to weather and the long shipping distance, coffee beans often took a very long time to reach Europe. It was precisely because of this aging that the beans lost their acidity, gained body, and developed a unique flavor that was deeply loved by European coffee connoisseurs.

Of course, aged beans aren't simply coffee beans left in a warehouse for a few years, because over time, coffee beans will rot or even become moldy and turn into bad beans. To recreate the flavor of those days, Front Street Aged Mandheling gradually developed a standardized production model.

Many coffee connoisseurs who come to FrontStreet Coffee like to order a cup of Mandheling to savor its herbal flavors and caramel-like sweetness. Regardless of the type, Mandheling seems to share common characteristics, which are inseparable from Indonesia's unique coffee processing method. Indonesia's climate is humid, making it difficult to dry coffee for extended periods. To avoid rain and moisture, locals had to devise an alternative processing method — wet hulling/Giling Basah.

Although it sounds similar to the most common wet processing, wet hulling is actually quite different. As a processing method, wet hulling has two driving factors: moisture and cost (saving water reduces expenses). Coffee processed with the wet hulling method has a distinctive earthy flavor. Due to fermentation during processing, its acidity and brightness are on the lower side, while the body is enhanced.

Actually, whether it suits you depends on what kind of coffee flavor you prefer. Some people like prominent floral and fruity notes; some are drawn to the flavors brought by special processing methods; and some enjoy the body and unique herbal, earthy flavors in Front Street Mandheling coffee.

FrontStreet Coffee provides the following brewing reference:

Dripper: Kono Coffee-to-water ratio: 1:15 Dose: 15g Water temperature: 88°C

For brewing beans, Front Street recommends using freshly roasted coffee beans for brewing , as this allows you to experience the coffee's rich flavors to the fullest . The coffee beans shipped by FrontStreet Coffee are all within 5 days of roasting , because Front Street knows well that the freshness of coffee beans has a great impact on flavor . Front Street's roasting philosophy is " Freshly roasted good coffee ," so that every customer who places an order receives the freshest coffee possible . The resting period for coffee is about 4-7 days , so by the time customers receive it, it's at its optimal flavor .

Use a staged extraction: bloom with 30g of water for 30 seconds, then pour in a slow circular motion until the scale reads 125g for the first stage. When the water level drops and is about to expose the coffee bed, continue pouring until 225g and stop. When the water level drops and is about to expose the coffee bed again, remove the dripper. (Timing starts from the beginning of the bloom.) The V60 dripper extraction time is 2'00", while the Kono dripper takes slightly longer at 2'10".
