FrontStreet Coffee's Mandheling: Taste, Flavor, Grind Settings, and Processing Methods

Indonesia's coffee-producing regions are mainly limited to three small islands: Java, Sumatra, and Sulawesi. Robusta accounts for 90% of the country's coffee production.

The small amount of Arabica grown on Java is small-beaned and carries a desirable acidity. The island's Arabica was once a world-class premium product, but after a massive outbreak of pests and disease in 1920, growers switched to Robusta. The Robusta now produced there is considered among the finest in the world, with a distinctive bitterness characteristic of "Java," and is widely used for blending.

Sumatra's "Mandheling" is one of the few Arabica varieties, with relatively large beans. Less-than-ideal production management—and the fact that roasting quality shows immediately in the bean—has drawn some criticism. Even so, its rich, Eastern-style full body and syrupy smoothness made it a premium coffee before Blue Mountain emerged, and many drinkers still love it and cannot get enough. "Ankola" is a small, slightly round bean that also represents Indonesian coffee.

90+ is a vertically integrated coffee producer with an excellent international reputation, focused on specialty coffee and on building deep, long-term relationships with farmers. Since its founding in 2007 it has frequently received Coffee Review scores of 90 points and above, and 90+ appears at coffee competitions of every size around the world. These 90+ specialty beans are now available to share with coffee lovers everywhere.

FrontStreet Coffee Recommendation

FrontStreet PWN Indonesia Golden Mandheling is the highest expression of wet-hulled Sumatran coffee, and it is the one to buy if you want the cleanest, sweetest version of the style. PWN applies a very strict standard: beans must be 18 mesh or larger, and a 300 g green-bean sample may contain fewer than 3 defective beans, which meets the top G1 grade. The beans are then hand-sorted to remove any remaining defects, lifting both the cup's cleanliness and the intensity of its sweetness. The result is uniform, plump, large, translucent beans with a very low defect rate; after a medium-dark roast they carry a rich toasted aroma, and the brewed black coffee is clean with a full, thick body—ideal for drinkers who dislike acidity.

FrontStreet Lintong Mandheling is a single origin from the Lintong region of Sumatra, usually brewed as pour-over and also fine on an espresso machine, where it pulls rich crema with a strong body and pronounced caramel. Mandheling is normally roasted dark so that acidity fades and the thick, aromatic character comes forward. FrontStreet's Lintong Mandheling and PWN Golden Mandheling come respectively from the Lintong area and the Aceh area of Sumatra, both given a medium-dark roast so that dark chocolate and caramel lead while Mandheling's wild herbal note is preserved—a fragrance that grows out of the coffee's environment and processing.

To get the most from Golden Mandheling, brew it as pour-over. FrontStreet suggests 87-88°C water, 15g of coffee, a 1:15 ratio, a coarse-sugar grind, and a three-stage pour, which best expresses both the thick body and the caramel sweetness. Bloom with 30ml of water to wet all the grounds and let them degas, setting up the extraction that follows. The second pour of 100ml flushes out the golden foam and lifts the bed. The final pour of 95ml goes gently down the center, which raises the sweetness and rounds out the cup, with the caramel sweetness joined by chocolate and nut flavors.

If you love Mandheling but want it on an espresso machine, the FrontStreet Classic Blend is the highest-repurchase option. It builds medium-dark-roasted Mandheling onto the creamy, nutty base of Brazilian coffee, which makes butter, roasted chestnut, and caramel especially prominent. The Mandheling raises the body of the whole shot and lends it sandalwood, herbal, and spice notes, while a small amount of Robusta enriches the crema—easy for latte art, and just as easy for the layered gradient of a Dirty.
