What is a unique characteristic of Robusta coffee beans compared to Arabica?

Robusta coffee beans are known for having fewer oils and sugars compared to Arabica beans, which contributes to their distinct flavor profile and overall characteristics. This difference is significant because the higher oil and sugar content in Arabica beans enhances their flavor complexity and sweetness, making them generally more favored in specialty coffee markets. Robusta beans tend to have a more robust, bitter taste and are often used in espresso blends for added crema.

Fewer oils and sugars in Robusta make them less prone to spoilage, which can be an advantage in terms of shelf life and storage conditions. Additionally, Robusta’s lower acidity level can complement certain coffee blends and offerings. Understanding this fundamental difference in composition can help in selecting the appropriate bean type for various brewing methods and taste preferences.
