What is Sumatra coffee?

Sumatra coffees come from Indonesia’s Sunda island of Sumatra, the largest Indonesian island in the Malay Archipelago. This region, known as the green coffee belt, benefits from tropical weather and a hot, humid climate that provides ideal coffee-growing conditions.

Sumatran coffee uses a unique processing method called Giling Basah. Due to frequent rainfall, coffee seeds are dried only to around fifty percent moisture before being wet-hulled. This process removes the parchment layer and introduces mild fermentation, creating the coffee’s signature earthy flavour.

Most Sumatran beans are roasted dark to enhance richness and balance out natural variances caused by the multi-stage wet-hulling process.

Sumatra coffee characteristics

Sumatran coffee has a full-bodied flavour with earthy and chocolatey notes. Its lower acidity allows the deeper tones to shine through, with tasting notes that can include moss, peat, wild mushroom, pepper and herbs. Like a fine whisky, each cup offers complex layers of flavour.

A brief history of coffee in Sumatra

The Dutch introduced coffee to Indonesia in 1699 after discovering ideal growing conditions on Java, and soon expanded to Sumatra. By the early 1700s, coffee from these islands was being exported to Europe through the Dutch East India Trading Company. Indonesia became one of the world’s first large-scale coffee producers outside Arabia and Ethiopia.

Today, Indonesia remains the world’s fourth-largest coffee producer, exporting around four hundred thousand tons each year, with Sumatra a key contributor.

Where is Sumatra coffee grown?

Sumatran coffees are grown in Takengon, Bener Meriah, Lintong, Sidikalang, Dolok Sanggul and Seribu Dolok, particularly around Lake Toba. Grown between eleven hundred and sixteen hundred metres above sea level, the coffee thrives in fertile volcanic soil rich in minerals and nutrients. These andesitic soils, formed from volcanic sediment, give rise to the term volcano or volcanica coffee.

Did you know these three coffee facts?

Sumatra is home to one of the world’s rarest coffees, Kopi Luwak, made from beans eaten and excreted by civet cats. This unique coffee dates back to the nineteenth century and produces a distinctive, smooth flavour.

Unroasted green coffee beans from Sumatra often have a bluish hue.

Although Indonesia is the fourth-largest coffee producer in the world, ninety-two percent of Sumatran coffee comes from small, independent farmers and cooperatives. Buying Sumatran coffee supports these communities and their artisanal production methods.
