Robusta Coffee: One of two species of coffee plants (the other is Arabica) grown for human consumption and considered the least desirable of the two. Grown at lower altitudes, robusta has less flavor, more caffeine and is more plentiful than arabica. The name comes from the plant's ability to withstand disease, high heat and humidity. Robusta is used in many commercial blends.
