Sumatra Robusta Green Coffee Beans
Sumatra Robusta green coffee beans from Indo Agriculture are sourced from selected coffee-growing regions on the island of Sumatra, Indonesia. These beans are specifically chosen for roasters, traders, and industrial buyers who need consistent, robust flavor, stable quality, and reliable supply for espresso blends, instant coffee, and ready-to-drink (RTD) coffee products.
With a naturally higher caffeine content and strong body, Sumatra Robusta is ideal for adding crema, mouthfeel, and intensity to coffee blends while keeping production costs competitive.
Indo Agriculture supplies high-quality Sumatra Robusta green coffee beans from selected coffee-growing areas in Sumatra, Indonesia. These unroasted beans are valued for their strong body, bold flavor, low acidity, and high caffeine content, making them ideal for espresso blends, instant coffee, and a wide range of value-added coffee products.
Our Robusta coffee is sourced from smallholder farmers and cooperatives in major producing regions such as South Sumatra, Lampung, and Bengkulu. Volcanic soils and a tropical climate help create the distinctive character of Sumatra Robusta coffee.
