I've heard that there are different types of coffee beans. What's the difference?

The main difference between different types of coffee beans is their flavor and aroma. Arabica beans, which are most commonly used to make espresso-based coffees, have a fruity, floral, and citrusy taste. Robusta beans, on the other hand, tend to be stronger and harsher with more pronounced notes of cocoa, chocolate, and caramel.
