The Mystical Realm of Sumatra's Gayo Mountains

Sumatra, an island known for its many ethnic groups and complex languages, was world-famous during the Age of Sail for its rubber and coffee. The Gayo Mountain range lies in northern Sumatra, and these mountains are volcanic. Naturally fertile volcanic soil, combined with an equatorial rainforest climate and a warm, humid environment, gives the region built-in advantages for cultivating excellent coffee.

The beans from this region come from the Typica variety. Their flavor is cleaner than ordinary Mandheling and carries a subtle licorice taste and fruit aroma. Raised in nature's grand environment, these are organic beans that coexist with butterflies, bees, squirrels and many other creatures.

Beneath the Veil of Mystery

Coffee from the Gayo Mountains goes by many alternative names in Taiwan, such as Green Treasure Mandheling, Gayo Mandheling, Takengon Mandheling, Aceh Coffee and Lake Tawa. In fact, they all refer to the same bean. How could anyone not be excited by a coffee grown in such a mysterious place?

Mandheling Insights

Mandheling suits single-origin coffee, much like the Panamanian single-origin covered earlier, and it is a coffee of strong character. Mandheling has a rich, solid mouthfeel with a slight, pleasant acidity. Roasted dark, it releases fragrant, bitter and mellow aromas. Mandheling is also the gentleman among coffees. Grown at high altitude, it stands for perseverance and tenacity. With one sip you can almost feel the thrill of galloping through the rainforest. This robust character has earned Mandheling the title "Caesar Augustus of Coffee." Rich and with a slight acidic bitterness, it also symbolizes love as the best spiritual healer, refined through bitterness and sourness.

Mandheling beans are relatively large, and hand picking during harvest is essential to guarantee quality. Coffee lovers have a theory of their own: among all coffee beans, Mandheling is considered rather unattractive in appearance, but the less appealing it looks, the better, richer and smoother it tastes.

FrontStreet Coffee Recommendation

For the Aceh Gayo style, FrontStreet Coffee recommends its PWN Golden Mandheling. PWN buys high-quality Mandheling green beans and sorts them with one mechanical and several manual rounds to select only plump, defect-free beans; Golden Mandheling is the flagship, graded 18 mesh and above with fewer than 3 defective beans per 300 g sample, the top G1 grade, after three rounds of hand sorting. The beans are uniform, large and translucent, and a medium-dark roast leaves a rich roasted aroma, a clean cup and a full body, ideal for anyone who dislikes acidic coffee.

The whole range is grown around Sumatra's Gayo mountains and Lintong, in a tropical setting where humidity runs 70-90% year-round, typhoons are common and annual rainfall exceeds 2,000 mm. That weather rules out the long 2-3 week sun-drying used in Africa and makes full washing too costly, so growers developed the region's signature semi-washed wet-hulled method, stripping the parchment while the beans are still half-dry and exposing them to the air to speed drying while they take on the microbes that create Mandheling's distinctive wild flavor.

To brew Golden Mandheling, FrontStreet recommends 87-88°C water, 15 g of coffee, a 1:15 ratio and a coarse, granulated-sugar grind, poured in three stages: a 30 ml bloom to wet the grounds and let them degas, 100 ml to draw out the golden crema and lift the bed, then a gentle 95 ml centre pour to lift sweetness. The cup comes out thick and full-bodied, with caramel sweetness and chocolate and nut flavors. FrontStreet's Classic Blend, its most repurchased espresso blend, brings medium-dark Mandheling together with Brazilian creamy, nutty notes for butter, roasted chestnut and caramel, plus sandalwood, herbal and spice notes and a touch of Robusta for a fuller crema.
