Mandheling Coffee Beans Pour-Over Flavor Profile Introduction How to Brew Indonesian Gold Mandheling Coffee for the Best Taste

Mandheling coffee possesses an exceptionally distinctive flavor profile characterized by its low acidity, rich aroma, and pronounced bitterness, perfectly aligning with traditional coffee expectations. Consequently, people's attitudes toward it are polarized—some become irrevocably devoted, while others avoid it entirely. For FrontStreet Coffee, however, the sweet, rich, and full-bodied Mandheling represents an irreplaceable favorite. Today, let's explore the unique characteristics of Mandheling and introduce its pinnacle version—Golden Mandheling Coffee.

The Historical Origins of Indonesian Coffee

If you're familiar with coffee history, you likely know that Indonesia shares a long-standing relationship with coffee. Initially, coffee grew in Ethiopia. In 1699, Dutch colonists brought coffee plants to Indonesia via Yemen. Sumatra, part of Indonesia, ranks as the world's sixth-largest island, home to over 50 million people. Along with Borneo and Java, it constitutes one of the three main islands forming this nation.

Subsequently, coffee proliferated rapidly throughout Indonesia, which became one of the world's largest coffee-producing nations. During that era, Indonesian coffee was exported from Jakarta on Java Island, which explains why Java was historically recognized as producing the world's finest coffee. Consequently, it was commonplace for coffee packaging and export bags to bear the label "Java."

The Legend of Mandheling Coffee

Legends and stories about coffee abound, particularly from ancient, traditional regions. For instance, Sumatran coffee is predominantly sold under the name "Mandheling." In reality, the term "Mandheling" refers to an indigenous tribe inhabiting Sumatra Island, rather than coffee from a specific growing region.

The legend dates back to World War II when a Japanese soldier tasted a mellow coffee and inquired about its name from the coffee shop owner. Mistaking the question as an inquiry about his personal background, the owner responded with "Mandaining." In Japanese pronunciation, "Mandaining" closely resembles "Mandheling," and thus the name was recorded. Unable to resist the allure of this delicious coffee, the soldier, upon returning to Japan, commissioned Japanese merchant friends to find Mandheling coffee in Indonesia. Consequently, several tons of Mandheling coffee beans were imported back to Japan for sale. In those early days, recognition of premium coffee largely followed Japanese trends, and due to Mandheling's immense popularity in the Japanese coffee market, it gained worldwide fame.

That Indonesian merchant from the story is now the renowned PWN company. PWN registered "Golden Mandheling" as a trademark in its early days; Japanese competitors didn't concede and registered "Supreme Golden Mandheling" as their own trademark. Due to different brands, companies, and marketing strategies, determining which tastes better or holds higher status remains a subjective matter.

Authentic Golden Mandheling

Since "Golden Mandheling" is a registered trademark of PWN, only Golden Mandheling originating from PWN represents the genuine article. Many merchants in the market label their roasted coffee beans as Golden Mandheling. Consumers wishing to verify whether their purchased Golden Mandheling is authentic PWN product can request proof from merchants, such as PWN Golden Mandheling green bean sack bags and certificates to confirm authenticity.

FrontStreet Coffee's PWN Golden Mandheling green beans are of the highest G1 grade, with bean sizes above 18 mesh and fewer than 3 defective beans per 300-gram sample. PWN maintains stringent production requirements for Golden Mandheling coffee beans. After mechanical screening, the beans undergo three rounds of manual selection to ensure complete removal of defective beans, thereby enhancing the coffee's cleanliness and sweetness.

The Unique Wet-Hulled Processing Method

Sumatra Island's coffee is renowned for its low acidity, which stems from several factors. Among these, the local farmers' post-harvest processing methods represent the most crucial factor. Compared to the washed processing method popular in Latin America, this approach to processing coffee cherries is more primitive and casual.

After coffee cherries are harvested, they undergo mechanical depulping on the same day to remove skin and pulp. These slimy, parchment-covered beans are then stacked in water tanks or bags for fermentation. Subsequently, the mucilage layer is washed away with clean water, and the parchment beans are placed in courtyards for drying.

When the parchment beans reach a semi-dry, semi-moist state, farmers pack them into bags and sell them to nearby coffee processing mills. Upon receiving the parchment beans, the mills remove the parchment layer, exposing the green beans directly for final drying.

Mandheling coffee processed using the wet-hulled method exhibits flavors reminiscent of spices and herbal plants, with subtle fruit acidity and a viscous, smooth mouthfeel. Due to its deep, mellow aroma and full-bodied texture, Mandheling coffee has gained worldwide recognition. With Mandheling's rise to fame, its unique wet-hulled processing method also became renowned. It can be said that the wet-hulled processing method and Mandheling coffee share a mutually reinforcing relationship.

Roasting and Brewing Recommendations

When FrontStreet Coffee's roasters received PWN Golden Mandheling green beans, they observed exceptionally uniform bean sizes with a blue-green color. To highlight Mandheling's rich, full-bodied character, they employed a medium-dark roast profile.

For brewing, to extract the rich body of PWN Golden Mandheling, FrontStreet Coffee recommends using a slower-flow pour-over dripper, such as the KONO dripper. To avoid over-extraction from prolonged contact between coffee grounds and water, Frontsteet suggests using a medium-coarse grind and 88°C water temperature for brewing.

Brewing Parameters:
Dripper: KONO Dripper
Water Temperature: 88°C
Coffee Dose: 15 grams
Coffee-to-Water Ratio: 1:15
Grind Size: Medium-coarse (Chinese standard #20 sieve, 70% pass rate)

Regular readers of FrontStreet Coffee articles should be quite familiar with the three-pour method used by our baristas, as this technique imparts richer layering to the coffee.

First, pour 30 grams of hot water to fully saturate the coffee grounds and let bloom for 30 seconds. Then, using a small water stream, slowly pour in a circular motion from the center to reach 125 grams for the second segment. When the water level in the dripper drops to just above the coffee bed, continue pouring to reach 225 grams for the third segment. Stop pouring and wait until all water has dripped through into the serving pot below, then remove the dripper. Total extraction time should be approximately 2 minutes.

After brewing, FrontStreet Coffee's PWN Golden Mandheling reveals nutty notes. As the temperature slightly decreases, aromas of cinnamon spices, herbs, and sweet melon emerge, accompanied by caramel-like sweetness. The mouthfeel is clean and full-bodied.
