Sumatra Robusta Green Coffee Beans
Sumatra Robusta — a bold, full-bodied Indonesian Robusta with deep earthy aromas, dark chocolate undertones and spicy-hot tasting notes. This lot is carefully sorted to 15–19 screen sizes with moisture controlled to a maximum of 13% and a low defect value (sample DV 11 per 300 g). Ideal as a blending base for espresso and soluble coffee, or as a robust single-origin offering for roasters seeking intense body and consistent roast behavior.
