In terms of production, Indonesian coffee has always ranked among the top globally, with substantial cultivation of both Arabica and Robusta. Its coffee system is highly complex, producing a dizzying array of coffee varieties. The most familiar to everyone are "Sumatra Mandheling Coffee," "Sulawesi Coffee," "Java Coffee," and the once-fashionable "Kopi Luwak."

Sumatra is a key specialty coffee region in Indonesia, primarily producing Mandheling coffee, with production concentrated in the northern province of Aceh and the province of North Sumatra (North Sumatra for short) to the south of Aceh. These two major regions are distributed around well-known local volcanic lakes, namely Lake Toba and Lake Tawar, traditionally known as the Lintong region and the Aceh region.

Sumatra has a tropical rainforest climate, with abundant rainfall year-round, humid air, frequent typhoons, and scarce freshwater resources. When processing large quantities of coffee beans, locals could neither use the traditional washed method nor carry out long sun-drying. As a result, coffee farmers developed the wet-hulled method, which takes only four days, greatly compressing fermentation and sun-drying time and saving considerable labor. This is precisely why Sumatra Mandheling has that unique Southeast Asian character with intertwined herbal, spicy, and woody notes.

The wet-hulled method works as follows: after harvesting, the coffee cherries are first poured into a water tank, using flotation to remove underripe cherries. Then the outer skin is removed with a depulper, and the beans are directly placed in a pool for a short fermentation of a few hours. At this point, a small amount of mucilage remains on the parchment surface, which is removed by scrubbing. The parchment beans are then taken for drying. When the green beans are first dried to a moisture content of 30-40%, the farmers sell the beans to collectors. After receiving these semi-dry parchment beans, the collectors directly hull them, removing the mucilage and parchment to obtain green beans. Although each step is greatly shortened in time, the "naked beans" still absorb moisture from the hot and humid air, giving the resulting Mandheling coffee an extra layer of musty character.

The green coffee beans with the parchment removed need to continue drying to a moisture content of 12-13% before being bagged and sent for inspection. The relatively rough processing of the wet-hulled method leads to a higher defect rate in green beans. To meet Indonesian export standards and increase selling prices, green bean traders must go through multiple rounds of sorting to remove irregular defective beans. The well-known Indonesian green bean company Pawani Coffee Company (PAWANI, abbreviated as PWN) is famous for producing multiple specialty Mandheling coffees, and "Golden Mandheling" is its signature product — the very Golden Mandheling coffee on Front Street Coffee's bean list.

The grading of Indonesian green coffee beans is based on the number of defective beans, using 300 grams of green beans as the benchmark. The highest grade, Grade 1, requires fewer than 11 defective beans. Golden Mandheling not only meets Indonesia's G1 standard, but its green beans also undergo an initial machine sorting to select batches of 18 mesh or larger, followed by three rounds of manual sorting to ensure consistent color and uniform bean shape. After Front Street Coffee acquired Golden Mandheling green beans, cupping comparisons revealed that it not only sheds the earthy and muddy flavors common in ordinary Mandheling, but its spicy and herbal notes are also particularly clear, with overall cleanliness greatly improved.

For coffee like Golden Mandheling with a rich body and distinct regional flavor, Front Street Coffee recommends extracting and enjoying it as a pour-over black coffee to better capture the coffee's aroma. Coffee beans shipped by Front Street Coffee are all freshly roasted within 5 days, ensuring they are at peak freshness when you receive them, adding more layers to the flavors in your cup.

Golden Mandheling coffee beans are medium-dark roasted, with a loose internal structure and strong water absorption capacity. If you apply the water temperature and grind size used for light-roasted beans, over-extraction is likely, resulting in unpleasant burnt bitterness and astringency. To avoid this issue, the baristas at Front Street Coffee (FrontStreet Coffee) lower the water temperature and coarsen the grind to reduce the release of bitter large molecules. Front Street uses hot water at 87 degrees Celsius and a medium grind size (70% passing rate on Chinese standard No. 20 sieve). For coffee that needs enhanced body, Front Street prefers to use the slower-flowing KONO dripper. Compared to the V60 dripper's large outlet, KONO's immersion effect is better, allowing coffee grounds to release more high-quality flavor compounds within the same extraction time.

Three-stage pouring: first pour 30 grams of water for a 30-second bloom, then from the center point, slowly pour in a thin stream in a circular motion to 125 grams. When the water level in the dripper drops to the point where the coffee bed is about to be exposed, continue pouring in a circular motion to 225 grams. Total extraction time is about 2 minutes.

The pour-over Golden Mandheling greets the palate with intense dark chocolate aromas, with roasted hazelnut, caramel, and melon flavors blending perfectly. The spicy notes are very prominent in the mouth, with a long, lingering finish.
