This roast type enhances the coffee’s unique characteristics and counteracts the high variance that’s caused by a multi-stage processing method and wet-hulling machines. When it comes to roasting Sumatra coffees, green coffee beans tend to end up as a dark roast. During the process, the wet-hulling machine helps ferment the coffee beans, contributing to their signature, earthy flavour. This machine-led process of wet-hulling involves friction-like movements that remove the coffee beans from their protective coating (known as the parchment). Beans are then “wet-hulled” to complete the drying process. However, due to Sumatra’s frequent rainfall, coffee seeds are left to dry until they’re at around 50% moisture content. Typically in the green coffee belt, when coffee seeds are removed from the cherry, they’re left to dry until there’s 11% moisture content.

Unlike other coffee varieties, coffee from this region has its own processing method called ‘Giling Basah’. This coffee-growing region is blessed by tropical weather and a hot and humid climate that create perfect coffee-growing conditions. The Sunda Islands also include Borneo and Sulawesi, and the area is known as the ‘green coffee belt’. Sumatra coffees come from Indonesia’s paradisiacal Sunda island of Sumatra, the largest Indonesian island in the Malay Archipelago.
