Golden Mandheling Coffee Roasting Recommendations: How to Best Enjoy Golden Mandheling Coffee

BIWA Golden Top FrontStreet Coffee Mandheling

Indonesia is a southern paradise made up of many beautiful islands.

One of those islands, Sumatra, has a Lintong region in its north. The beans hand-picked and hand-processed from limited farms in this region are called GOLD TOP MANDHELING.

After being hand-picked and hand-processed, the selected beans undergo SEMI-WASHED processing, sun-drying, and hulling, followed by a drying process, two rounds of cleaning, and four rounds of hand-picking. They can therefore be considered specially selected premium coffee beans.

Selection Process

1. The purchasing company at origin buys deep-red coffee fruit directly from farmers.

2. It immediately removes the coffee pulp to extract the PARCHMENT. The parchment is then placed in a small water tank for washing. (The purpose is to remove impurities from the parchment, roughly 1–2 minutes.)

3. The washed beans, after sun-drying, are shipped directly to the export company in Medan. The export company then gives these beans two days of sun-drying and hulling. Because the moisture content of the processed beans is still as high as 40%, sun-drying is needed to bring moisture down to 12.5%.

4. The fully dried beans must undergo specific-gravity treatment, air-volume sorting, and screen sorting to remove SILVER SKIN, small beans, defective beans, and foreign objects. Finally they undergo HAND-PICKING to reach the highest grade, GOLD TOP MANDHELING.

GOLD TOP MANDHELING

The origin of FrontStreet Coffee's Golden Mandheling is that it was initially developed through contract cooperation with Japanese buyers who traveled to Indonesia. From tree-species selection and cultivation management to harvest processing, every quality-control, selection, and processing procedure was planned and managed by the Japanese. Even the storage stacking after bagging was specially planned. The process can be called extremely rigorous. FrontStreet Coffee's Golden Mandheling was thus created with extremely superior quality and has received quite high praise in the coffee industry. Later, because GOLD MANDHELING was registered as a trademark locally in Indonesia, the name was changed to "GOLD TOP MANDHELING."

When we roast this bean, we break away from the usual method of roasting Mandheling-series beans until second crack is dense and the beans turn dark and shiny. Instead, we choose to drop the beans at the end of first crack, before second crack. Without the bitter taste, the cup carries a slight, soft fruit acidity, making the aroma more subtly prominent.

FrontStreet Coffee Recommendation

Mandheling comes from the Indonesian island of Sumatra, where more than 60% of the country's Arabica and Robusta is grown; the higher ground of Aceh in the north and North Sumatra to its southeast is where the Arabica—marketed as Mandheling—is produced. What gives Sumatra its distinctive character is the local wet-hulled process, developed because the rainy season overlaps with the harvest. Sun-drying for two to three weeks is impossible and fully washed processing costs too much water and labor, so farmers pulp the fruit, give it a brief wash, and then hull off the parchment while the beans are still semi-dry. Exposing the bean early speeds drying but also lets it absorb airborne microbes—the source of Mandheling's one-of-a-kind, wild flavor.

Among Mandheling beans, the one that satisfies even the most exacting drinker is Golden Mandheling from Indonesia's PWN company. PWN selects only beans of 18 screen size or larger and requires fewer than three defective beans in every 300-gram green-bean sample, meeting the top G1 standard, then removes flaws through three rounds of hand-sorting to lift both the cup's cleanliness and the intensity of its sweetness. That rigor is exactly why PWN Golden Mandheling's quality is so high and its supply so limited. Golden Mandheling is a big name, but it is supplied mainly to the Japanese and American markets, so very little genuine Golden Mandheling reaches other countries each year. Mandheling is usually roasted dark to soften its acidity and play up its mellow richness, and both FrontStreet Coffee's Lindong Mandheling, from Sumatra's Lintong region, and its PWN Golden Mandheling, from Aceh, are roasted medium-dark to build black-chocolate and caramel flavors while keeping Mandheling's wild herbal lift.

Golden Mandheling shows best as a pour-over. FrontStreet Coffee recommends 87–88°C water, 15g of coffee, a 1:15 ratio, and a coarse-sugar grind, poured in three stages—30ml to bloom, 100ml to bring out the golden foam and raise the bed, then a gentle 95ml down the center to lift sweetness. The result is a thick, full body with caramel sweetness and notes of chocolate and nuts, ideal for anyone who prefers a rich cup with little acidity. If you would rather use an espresso machine, FrontStreet Coffee's Classic Blend—its most repurchased—builds on Brazil's creamy, nutty base with medium-dark Mandheling, pushing butter, roasted chestnut, and caramel to the front and adding sandalwood, herbal, and spice notes; a touch of Robusta rounds out the crema, making latte art or a layered Dirty easy to pull.
