How does Robusta coffee differ from Arabica?

Robusta coffee is characterized by having a higher caffeine content compared to Arabica coffee, which contributes to its distinct flavor profile. Coffee experts often describe Robusta coffee as having a more bitter taste due to the increased caffeine levels and the presence of certain compounds that enhance bitterness. This higher bitterness can mask some of the more subtle flavors typically found in Arabica, making Robusta less complex and smoother in comparison.

In addition to its flavor, Robusta plants are hardier and more resistant to pests and diseases, which allows them to thrive in harsher growing conditions. The beans themselves are generally rounder and smaller than Arabica beans.

The other options present characteristics that are more aligned with Arabica coffee, such as sweetness and floral aromas, which are not typical of Robusta. Therefore, the defining traits of Robusta—higher caffeine content and bitterness—help differentiate it clearly from Arabica.
