Origin: Indonesia

Variety: Typica

Grade: G1

Altitude: 1350-1500 meters

Processing Method: Wet-Hulled

Roast Level: Dark Roast

The giant island of Sumatra was known in ancient times as the "Spice Islands." It is Indonesia's main coffee-producing region, and Sumatran coffee is known to the world as "Mandheling." The Lintong region, on Sumatra Island, is renowned for its distinctive richness, body, and sweet aftertaste.

Mandheling green beans can look unattractive: the local wet-hulled processing leaves many cracks in them. Yet Mandheling is regarded as the world's most mellow coffee. It takes dark roasting beautifully-low acidity, rich aroma, and a mild, fragrant fullness. Traditionally, its distinctive bitterness gives way to a unique sweetness.

Pour-over Brewing Recommendations: Water temperature 88°C, 15g coffee grounds, 30g hot water for bloom, second pour to 210g total, brewing time 1:50 seconds

FrontStreet Coffee Recommendation

Mandheling is usually roasted dark precisely because that softens its acidity and brings out its mellow, fragrant depth. FrontStreet's Lintong Mandheling and PWN Golden Mandheling come respectively from the Lintong region and the Aceh region of Sumatra, both roasted medium-dark to present black chocolate and caramel sweetness while keeping Mandheling's wild herbal fragrance-a scent born of the island's growing environment and its wet-hulled processing. For the finest expression, try FrontStreet's PWN Golden Mandheling: sourced by the PWN company, machine-sorted once and hand-sorted three times, with large, even, blemish-free beans. After medium-dark roasting it shows rich roasted aromas, a clean cup, and full, heavy body-ideal for anyone who dislikes sour coffee. To brew it, use 87-88°C water, 15g of coffee ground to a coarse-sugar texture, and a 1:15 ratio with a three-stage pour: 30ml to bloom and degas, 100ml to lift the bed and draw out the golden foam, then a gentle 95ml poured softly in the center to lift sweetness. The finished cup shows a thick body, caramel sweetness, and chocolate and nut flavors.
