What is "robusta coffee"?

Robusta coffee is a species of coffee plant that is known for its hardiness and high caffeine content. It is easier to cultivate than Arabica and can grow in lower altitudes and warmer climates. Robusta coffee beans have a stronger, more bitter taste and a higher acidity level than Arabica. They are often used in commercial coffee blends, instant coffee, and espresso blends, as they can provide a rich crema and are more cost-effective than Arabica beans. Robusta coffee is grown in several countries, including Vietnam, Indonesia, Brazil, and Uganda. While not as highly prized as Arabica coffee, Robusta is still an important coffee variety and is an essential part of the global coffee industry.
