What kind of beans are most commonly used in espresso roasting?

• A. Robusta and Liberica
• B. Arabica and Excelsa
• C. Arabica and Robusta
• D. Robusta and Arabica blends

Answer: (C)

The selection of Arabica and Robusta beans for espresso roasting is due to their distinct characteristics that complement each other well in espresso preparation. Arabica beans are known for their smooth, nuanced flavors and aromatic qualities. They possess a wide range of flavor profiles that can include fruity, floral, and nutty notes, making them highly sought after for specialty coffee.

Robusta beans, on the other hand, are appreciated for their strong, bold flavor, increased crema production, and higher caffeine content. This makes them particularly valuable in espresso blends, where a rich and robust flavor profile is desirable. Additionally, Robusta beans help to stabilize the crema, contributing to the desired visual and textural qualities of espresso.

Blending these two varieties allows roasters to create a balanced flavor profile that enhances the overall espresso experience, providing both complexity and body. Utilizing both beans is a common industry practice, reinforcing why the combination of Arabica and Robusta is seen as a standard approach for espresso roasting.
