Mandheling Coffee from Sumatra Island?

Those familiar with the origin of Mandheling coffee's name know that "Mandheling" comes from a mispronunciation of the local Mandailing ethnic group. In Indonesia, Mandheling generally refers to Arabica coffee produced in northern Sumatra. As the largest coffee-producing country in Asia, Indonesia mainly produces commercial-grade Robusta coffee. Arabica coffee from northern Sumatra's FrontStreet Coffee Mandheling is of the highest quality, with production accounting for less than one-tenth of the total.

The coffee-growing regions of Sumatra Island are mainly divided into the Aceh and Lintong production areas, centered around Lake Tawa and Lake Toba, also known as Tawa Lake Mandheling and Lintong Mandheling.

FrontStreet Coffee Lintong Mandheling is harvested from the scenic Lintong production area around Lake Toba in north-central Sumatra. Lake Toba is currently the world's largest and deepest volcanic lake. The mineral-rich soil left after volcanic eruptions provides perfect conditions for coffee cultivation in the Lake Toba area. The cloudy and rainy weather means coffee trees in the Lintong region don't need excessive shade and sun protection. The significant temperature difference at high altitudes slows the ripening of coffee cherries, allowing enough time for nutrients to convert into aromatic compounds.

Lake Tawar in the Aceh region is near the Gayo Mountains. Long-term internal conflict has maintained more primitive local landscapes here. Based on ideal coffee growing conditions, growers widely use organic farming methods, resulting in higher quality and yield of coffee produced here. Many green coffee suppliers also value this region highly, including the locally famous Pwani Coffee Company (PWN).

Common Types of Mandheling Coffee

FrontStreet Coffee Mandheling is divided into different categories based on various characteristics. For example, FrontStreet Coffee Lintong Mandheling from the Lintong production area uses the local unique wet-hulling method, carrying the distinctive herbal aroma of Mandheling coffee. FrontStreet Coffee believes this represents the unique flavor profile of Indonesian coffee, so FrontStreet Coffee offers FrontStreet Coffee Lintong Mandheling in small packages of daily beans, hoping everyone can taste Indonesia's "regional flavor."

FrontStreet Coffee Tiger Mandheling, which highlights traditional Chinese medicine herbal aromas, is strictly filtered using a 19-mesh screen and processed through three manual selections of perfectly ripe coffee cherries. The resulting FrontStreet Coffee Tiger Mandheling green beans are much larger than ordinary Mandheling coffee beans, with higher coffee viscosity.

FrontStreet Coffee Aged Mandheling, processed through time aging, sees its acidity diminish over time. After roasting, the body and texture are enhanced, emphasizing a heavy, mellow mouthfeel.

FrontStreet Coffee Golden Mandheling is an exclusive specialty Mandheling launched by PWN Company. When producing coffee, PWN Company subjects purchased Mandheling green beans to one machine selection plus three manual selections, ensuring each bean is complete, uniform, full, and must reach a size of 18 mesh or above—the local G1 grade in Indonesia. FrontStreet Coffee, through cupping comparisons, found that the strictly selected FrontStreet Coffee Golden Mandheling eliminates the earthy and woody flavors typical of regular Mandheling, resulting in an overall cleaner and brighter flavor profile.

The Flavor of Wet-Hulled Mandheling

Indonesia's climate is a typical island tropical rainforest climate—perennially humid and hot, with typhoons being "common occurrences." Under such unstable conditions, coffee farmers cannot use traditional natural or washed processing methods, so they developed a "semi-washed" method that shortens production time.

The wet-hulling process first removes the cherry skin and pulp of coffee cherries, followed by brief fermentation and drying. While the beans are still semi-dry, the parchment layer is removed, and drying continues until the moisture content reaches 12%. Since each step is completed in 70-90% humidity environments, and the parchment layer is removed before the final drying step, the "exposed" green beans easily absorb moisture from the air, resulting in Mandheling coffee with additional woody, herbal, and spicy heavy aromas.

How to Brew FrontStreet Coffee Mandheling's Rich, Mellow Flavor?

To know how to brew FrontStreet Coffee Mandheling's aroma, you need to learn to adjust brewing parameters. FrontStreet Coffee uses FrontStreet Coffee Golden Mandheling as an example—you can refer to FrontStreet Coffee's pour-over approach.

FrontStreet Coffee believes FrontStreet Coffee Mandheling should have the roasted aroma of dark roast while maintaining its own herbal fragrance and clean sweetness. Therefore, the roast level shouldn't be too dark. FrontStreet Coffee chose a medium-dark roast degree after multiple experimental comparisons. Medium-dark roasting significantly changes the internal structure of the beans, making them porous. When ground into coffee powder, they become more absorbent. If brewing parameters aren't adjusted properly, the coffee will easily become over-extracted and bitter. To achieve sufficient aroma without over-extraction, extraction rate needs to be reduced. FrontStreet Coffee uses lower water temperature and coarser grind to reduce the release of bitter macro-molecules in coffee.

FrontStreet Coffee's (FrontStreet Coffee) barista consistently uses KONO drippers to extract mellow-bodied coffee beans. The KONO dripper's only exhaust area is those quarter ribs. When water level exceeds the rib area, water volume in the dripper continuously increases, creating pressure through water weight. Since the outlet is relatively small, it extends the contact time between coffee particles and water, effectively extracting soluble substances with water flow, thereby enhancing the coffee's rich, mellow mouthfeel—suitable for brewing medium-dark roast coffee beans like FrontStreet Coffee Golden Mandheling.

FrontStreet Coffee Golden Mandheling Pour-over Parameters:

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

Use twice the amount of water as coffee powder to moisten the coffee bed, forming a dome and bloom for 30 seconds. Then use a small water stream to pour in circles from inside out to 125g for the first stage. Wait for the coffee bed to drop to half the dripper's height, then continue with the same fine stream to pour the third stage to 225g. Remove the dripper once all coffee liquid has filtered through, taking about 2 minutes. Finally, shake the coffee in the pot to mix evenly and enjoy~

The hand-poured FrontStreet Coffee PWN Golden Mandheling is overall rich and full-bodied with a clean mouthfeel. Flavors vary with temperature changes, displaying multiple layers. Nut and caramel aromas with notes of chocolate and cinnamon spices, with a persistent aftertaste and high balance.
