Robusta is a type of coffee bean known for its strong flavor and higher caffeine content compared to its counterpart, Arabica. It is primarily grown in regions with a warmer climate, such as parts of Africa and Southeast Asia. The beans are smaller and rounder, and they tend to have a more bitter taste, making them popular for espresso blends and instant coffee. The Coffea canephora plant, which produces Robusta beans, is hardier and more resistant to diseases than Arabica plants. This resilience allows it to thrive in less-than-ideal growing conditions, contributing to its widespread cultivation. Robusta coffee is often used in commercial coffee products due to its cost-effectiveness and strong flavor profile.
