Unlock the distinct volcanic character of North Sumatran coffee with our Specialty Arabica Karo Green Beans. Sourced from the high-altitude plantations of the Karo Highlands, these beans are cultivated in mineral-rich soil at an altitude of 1200–1600 masl. This exceptional terroir, influenced by the surrounding active volcanoes, results in a dense bean with a complex and savory flavor precursor.
Processed using the traditional Semiwash (Wet Hulled) method, this specialty green coffee offers a powerful body and a clean, rustic profile. The Sigarar Utang and S-795 varietals, maintained at a precise moisture content of 12–14%, provide a robust foundation for roasters seeking to highlight deep spicy notes and a velvety mouthfeel.
