Sumatra Coffee Diseases - What are the Characteristics of Coffee from Sumatra Island

FrontStreet Coffee - Introduction to Sumatra Coffee

Mandheling Coffee is produced in Sumatra, Indonesia, in Asia, and is also known as "Sumatra Coffee." It has a very rich flavor: aromatic, bitter and full-bodied, with a hint of sweetness.

Coffee enthusiasts generally drink it as a single origin, but it is also an indispensable component of blends.

In the era before Blue Mountain became world-renowned, Mandheling was considered the finest coffee in the world. After roasting, the beans are quite large, and the raw beans appear brown or dark green with a special caramel-like aroma.

The taste is mellow and rich, with a sweet-bitter character and no delicate acidity, though it does carry bitterness. Production is relatively limited, which makes the price slightly higher than that of typical coffee beans.

Mandheling is produced in Sumatra, Indonesia, also known as "Sumatra Coffee." The main producing areas also include Java Island and Sulawesi Island, where 90% of the coffee is Robusta, a variety that resists coffee leaf rust disease effectively.

Among them, the Mandheling produced on Sumatra Island is the most famous. The finest of the premium traditional Arabica coffees grown in northern Sumatra are marketed under the names Lintong and Mandheling.

Specifically, Lintong refers to coffee grown in a small area in the southwestern part of Lake Toba, in the Lintong administrative region. Coffee smallholders there are scattered across a high, undulating clay plateau covered with ferns. Lintong coffee is grown without shade,

without chemical inputs, and is almost entirely owned by small private growers. Mandheling is a broader designation that includes Lintong coffee as well as growing areas in Diari (capital Sidikalang) and around northern Lake Toba under similar conditions.

FrontStreet Coffee Recommendation

If you want to taste what Sumatra's wet-hulled character is all about, FrontStreet Coffee's PWN Golden Mandheling is the benchmark. PWN buys in high-quality Mandheling green beans and screens them against strict standards, so the lots are uniform, plump and translucent with very few defects. After a medium-dark roast the beans give off a generous roasted aroma, and the brewed black coffee is clean in the mouth with a full, rounded body.

The profile is unmistakably Sumatran: low acidity, a heavy mouthfeel, herbal and dark chocolate aromas with a faint earthy note, and a long, sweet finish. It is made for drinkers who like a strong cup and do not want acidity.

FrontStreet Coffee recommends brewing it as pour-over at 87-88°C with 15 grams of coffee, a 1:15 ratio and a coarse-sugar grind. Pour in three stages - 30ml to bloom, then 100ml, then a gentle 95ml center pour - which brings out the full body and the caramel sweetness. If you want the same region in a milk drink, FrontStreet Coffee's Lintong Mandheling is a mellow medium-dark option with the wild herbal and spice notes that define the style.
