What is the key difference between arabica and robusta beans?

The key difference between arabica and robusta beans lies in their flavor profiles and caffeine content. Arabica beans are known for their sweeter and more acidic flavor, which often leads to a more complex and nuanced taste. This characteristic makes arabica highly sought after in specialty coffee markets. On the other hand, robusta beans tend to have a stronger, more bitter flavor due to their higher caffeine content, which contributes to a more earthy and straightforward taste.

Robusta coffee is often described as having a harsher flavor compared to arabica. Moreover, the increased caffeine content makes robusta plants hardier and more resistant to pests and diseases. Understanding these characteristics helps in appreciating the differences in coffee flavors and in making informed choices when selecting coffee.
