Sumatra accounts for 75% of the nations Robusta coffee production, which makes it the worlds largest producer of Robusta coffee. Sought after Arabica coffee is more scarce in Sumatra. The production of Arabica coffee is centered in the highlands of Northern Sumatra. Sumatran Arabica coffee is quite unique compared to Arabica coffee from other countries. The way in which Sumatran coffee is processed is very different from typical processing techniques used in coffee producing regions in South America and Africa, this is what makes Sumatran coffee so unique and special. The wet hull processing method is used in Sumatra, as opposed to the dry processing method used in other countries. In the wet processing method, the hulled beans (parchment or protected layer has been removed) are left for a short period to dry until they reach 50% moisture content. In the dry method, they are left for days or weeks to dry until the moisture content reaches around 11%. The shortened dry time and residual higher moisture content left behind is due to wet and volatile weather conditions on the island. As soon as the beans reach 50% moisture content, they are sold and transported to mills that have specialized wet hulling machines that complete the drying process. The machine ferments the coffee beans and in turn, adds to the complex flavor of the coffee. The unique processing techniques utilized in Sumatra have produced coffees that are known for presenting a heavy body, low acidity, and distinct earthy and chocolate tones.
