The Coffee Beans That Produce The Strongest Brew In The World

Not all coffees are the same, and some varieties are stronger than others. If you like your cup strong and full of caffeine, then be sure to use robusta beans.

Robusta accounts for about 40% of the world's supply, second only to arabica beans. The beans are loaded with caffeine — twice as much as the more common arabica beans.

Robusta beans are grown in countries like Brazil, Indonesia, and Vietnam. While they have a powerful caffeine punch, the flavor is bitter and intense, giving them a bad rep.

Because of this, robusta beans are typically included in blends and are often present in all kinds of roasts. However, you can buy pure robusta beans online on Amazon.
