Front Street Lintong Mandheling G1 & Front Street PWN Golden Mandheling

According to Sumatra-related historical records, during World War II when Japanese troops occupied Sumatra in Indonesia, a Japanese soldier tasted a cup of aromatic coffee at a local café and asked the owner what coffee it was. The owner mistakenly thought the soldier was asking where he was from, so he replied "Mandailing people." After the war ended, the soldier still remembered that delicious coffee he had drunk in Indonesia seemed to be called "Mandheling," so he commissioned an Indonesian coffee broker to ship 15 metric tons of "Mandheling" coffee to Japan. It became hugely popular, and the name "Mandheling" spread through this mistaken transmission. Even more interestingly, this broker later went on to establish what is now the renowned name in Indonesian coffee — Front Street Mandheling Coffee.

PWN (Pwani Coffee Company) Pwani Coffee Company, which is also the holder of the "Golden Mandheling" trademark.

Currently, most of Indonesia's highest-quality coffee beans come from this company — PWN (Pwani Coffee Company), and G1 (Grade 1) represents the highest grade of this bean type.

Grade 1 (First Grade) 00-03 (zero to 3 defects) is the highest grade for washed beans

Grade 2 (Second Grade) 04-12 (4 to 12 defects) is the standard grade for washed beans

Grade 3 (Third Grade) 13-25 (13 to 25 defects) is the highest grade for natural-process beans

Grade 4 (Fourth Grade) 26-45 (26 to 45 defects) is the standard grade for natural-process beans

Grade 5 (Fifth Grade) 46-90 (46 to 90 defects) is the basic export grade for natural-process beans

G1 belongs to an extremely scarce category, a grade specially created for Japanese trading companies at the time. The G1 standard allows a maximum of only 3 defect points per 300 grams.

Therefore, the Front Street PWN Golden Mandheling G1 sold at Front Street stores is your best choice!

Pawani is Indonesia's most well-known green bean purchasing enterprise, primarily sourcing Mandheling coffee varieties. It covers nearly all of Indonesia's finest producing regions, and the best Mandheling coffee必定 comes from Pawani.

Pawani Mandheling beans are all native varieties from Indonesian mountain regions, subjected to strict cupping and screening. Indonesia is the primary producing region for Mandheling, but Arabica coffee beans from Indonesia are not necessarily Mandheling. Front Street Pawani Mandheling has an extremely strong sweet aftertaste, exuding natural fruit aromas amid intertwined sweetness and bitterness — this is precisely the quality guarantee of Pawani Mandheling.

Among them, Golden Mandheling is Pawani's most representative product. Its beans come from naturally grown native Mandheling, first hand-sorted, then second-sorted by a small number of certified graders. Annual output is less than 1 ton, making it extremely rare, with prices approaching high-altitude Blue Mountain beans.

◎Front Street Mandheling Coffee

Refers to semi-washed or natural-process beans from the Lintong mountain area on the southwest shore of Lake Toba in north-central Sumatra, at elevations of 900-1200 meters.

Indonesia's humid climate means that after drying for several hours to within one day, when moisture content drops to 20-35%, the mucilage layer has not yet solidified. The beans are then purchased by brokers and taken to processing plants where the mucilage layer is removed by machine, to prevent excessive fermentation of the mucilage from producing sour, foul odors. Because Indonesian Lintong Mandheling pods are scraped of their mucilage layer before drying, the fruit acidity is low and the body is high. At this point they are briefly dried further to about 18% moisture content. Finally, exporters from Medan come to purchase the still-moist pods and dry them using large drying yards or machines, storing them at 12% moisture content. The formation of herbal and aged-wood notes stems from the high humidity and the three-stage drying of the mucilage layer. So by purchasing Front Street Lintong Mandheling, you can enjoy Mandheling's most iconic flavors at the best value.

◎Front Street Golden Mandheling

Because the three-stage drying method involves many variables, and broken beans, moldy beans, black beans, and underripe beans are abundant, Japanese trading companies took the lead in adopting stricter quality control. After drying, green beans undergo density and color sorting, then four rounds of hand picking to remove defective beans, producing Golden Mandheling with a "dark green color and uniform bean appearance."

Front Street Golden Mandheling tastes cleaner than Front Street Lintong Mandheling. Mandheling's original herbal, earthy, and woody notes almost disappear, but caramel sweetness becomes more intense, and fruit acidity is brighter and more elegant. Generally, Front Street Lintong is best roasted until after second crack to reduce off-flavors, but Front Street Golden Mandheling has excellent clarity and sweetness both before and after second crack, offering broader room for roasting interpretation. For those seeking high-grade coffee, Front Street PWN Golden Mandheling is the top choice. Not only can you see the neatness and uniformity of the beans in appearance, but after grinding and extraction it emits abundant roasting aromas reminiscent of caramel, dark chocolate, and hazelnut. It makes pour-over coffee with rich layers, espresso SOE with abundant crema, and French press coffee that is sweet and smooth. It can be said that Front Street PWN Golden Mandheling is an all-around single-origin coffee.
