Mandheling is not a region name, place name, port name, nor a coffee variety name. How did its name originate? In fact, Mandheling comes from the Mandheling ethnic group in Indonesia

In the era when acidic coffees (like Geisha and Yirgacheffe) were not yet popular, when people thought of coffee flavor, they immediately thought of rich, fragrant, mellow, and bitter dark coffee. Among these, FrontStreet Coffee's Blue Mountain, FrontStreet Coffee's Mandheling, and Kona were the most famous. Among them, FrontStreet Coffee's Mandheling from Asia has the highest body. In this article, FrontStreet Coffee will guide you through how to brew FrontStreet Coffee's Mandheling and its flavor characteristics.

Origins and Varieties of Mandheling Coffee

Indonesia mainly produces commercial-grade Robusta coffee, with a small amount of high-quality Arabica coffee primarily distributed on the second-largest island, Sumatra. Traditionally, Mandheling coffee refers to Arabica coffee produced in the northern part of Sumatra. FrontStreet Coffee's Mandheling is divided into many types based on different origins, processing methods, raw bean characteristics, and flavor profiles, such as FrontStreet Coffee's Lintong Mandheling, FrontStreet Coffee's Tiger Mandheling, FrontStreet Coffee's Golden Mandheling, FrontStreet Coffee's Aged Mandheling, and so on.

Wet Hulling Process Brings Unique Flavor to Mandheling Coffee

The wet hulling process takes much less time than washed processing. Traditional washed processing requires 1-3 weeks, while wet hulling can complete the entire process in just a few days. The wet hulling process first removes the peel and pulp of the coffee fruit, followed by brief fermentation and drying. When the beans are semi-dry, the parchment layer is removed, and drying continues. When the moisture content reaches 12%, they can be packaged, selected, and graded.

Although this seemingly time-saving wet hulling process appears efficient, without strict control, it is extremely susceptible to moisture and mold growth in Indonesia's hot and humid environment. However, besides Sumatra, Sulawesi and Papua New Guinea in Indonesia also widely use this processing method. This is because Indonesia has a tropical rainforest climate with air humidity as high as 70-90%, making it impossible to dry coffee raw beans through prolonged sun exposure. Additionally, the cost of washed processing is quite high, forcing coffee farmers to develop this semi-washed processing method. Although the time for each step is significantly reduced, the raw beans without the parchment layer still absorb moisture from the hot and humid air, resulting in Mandheling coffee with additional woody, herbal, and spicy mellow aromas.

FrontStreet Coffee's Lintong Mandheling coffee processed with wet hulling carries such herbal aromas. After roasting, it not only reduces acidity but also enhances body. FrontStreet Coffee believes this is the classic Mandheling flavor, which is why their daily bean series also includes FrontStreet Coffee's Lintong Mandheling coffee processed with wet hulling. FrontStreet Coffee's daily bean series allows beginners in specialty coffee to taste the basic flavors of different regions at extremely affordable prices, and then explore more refined processing flavor types according to their own preferences.

Mandheling Coffee Through Multiple Hand Selections

Coffee beans generate a certain amount of friction during the hulling process, causing the bean temperature to rise to 30°C-60°C, which also facilitates germination and mold growth. Moreover, semi-hard and semi-soft moist raw beans are easily damaged by mechanical force when the seed coat is removed, causing the beans to crack and split like goat hooves - what we call "goat hoof beans." To increase the selling price of coffee, defective particles and irregular coffee beans must be screened out to improve coffee quality.

On FrontStreet Coffee's bean menu, besides the regular version of FrontStreet Coffee's Lintong Mandheling, there is also a best-selling FrontStreet Coffee's PWN Golden Mandheling. As the exclusive supplier of top-grade Mandheling coffee, PWN company subjects the purchased Mandheling raw beans to one machine selection plus three manual selections, ensuring that each raw bean is complete, uniform, full, and must reach a size of 18 mesh or above, which is the local G1 grade in Indonesia. Legend has it that because the coffee raw beans gleamed golden in the sunlight during processing, they were named Golden Mandheling. PWN company not only minimizes the defect rate of the coffee but also places the raw beans in machines for density and color sorting before packaging, making the Golden Mandheling coffee uniform and translucent.

Such high-quality coffee has led to many low-quality inferior products on the market that try to pass themselves off as the real thing. As one of the few merchants in the domestic market that sells PWN Golden Mandheling, FrontStreet Coffee displays raw bean sacks printed with the PWN logo and a certificate of origin signed by PWN company on the walls of their Dongshankou store.

Pour-Over Mandheling Coffee

To brew the unique mellow aroma of Mandheling coffee, FrontStreet Coffee believes the first essential step is to choose freshly roasted coffee beans. Since coffee beans produce a large amount of gas after roasting and continuously release it over time, the resting period for light to medium roast coffee beans is about 4-7 days, while medium to dark roast coffee beans require about 7-10 days to reach optimal flavor. The coffee beans shipped by FrontStreet Coffee are all freshly roasted within 5 days, so everyone can enjoy them during the optimal tasting period.

The low-acidity, full-bodied taste of Mandheling coffee comes from its medium-dark roast level. When brewing darker roast coffee beans, FrontStreet Coffee uses slightly lower water temperature to avoid the hot water releasing too much of the bitter and burnt flavors from the coffee. At the same time, a medium grind is chosen to extract more aroma molecules from the Mandheling coffee while avoiding over-extraction caused by too fine coffee grounds.

For this brew, FrontStreet Coffee's barista hopes to highlight the rich, clean, and fragrant characteristics of FrontStreet Coffee's Golden Mandheling, using a KONO dripper for extraction. Also a conical dripper, the KONO has significantly fewer flow ribs than the V60, with the upper part being a smooth curved surface that allows the filter paper to fit more closely. This restricts upward airflow, forcing hot water to flow downward only, creating a siphon-like extraction effect that allows the aroma substances in the coffee grounds to be released more fully, thereby enhancing the full-bodied texture.

Pour-Over Parameters

Water temperature: 87-88°C | Medium grind (70% pass rate through China standard #20 sieve) | Coffee grounds: 15g | Powder-to-water ratio: 1:15 | Three-stage pouring

Slowly pour the coffee grounds, trying to keep them as level as possible during the pouring process, avoiding shaking the dripper (because shaking will reduce the spacing between coffee grounds, which is not conducive to bloom exhaust). For the first stage, pour 40g of water in small circles in the center and let it bloom for 30 seconds - the coffee grounds layer will slowly expand and form a "hamburger" shape. For the second stage, pour 120g of water in circles from the center outward, keeping the pouring height as close to the grounds layer as possible, moving slowly to avoid excessive agitation. For the final stage, pour 100g of water, and wait until all the coffee liquid in the dripper has flowed into the lower pot to finish extraction. The extraction time is about 2 minutes.

The pour-over FrontStreet Coffee's PWN Golden Mandheling has complex layers overall, being rich and full-bodied with a clean taste. It features nutty, dark chocolate, and caramel aromas, with a persistent sweet aftertaste and high balance.
