What are the two main types of coffee beans used by Starbucks?

The two main types of coffee beans used by Starbucks are Arabica and Robusta. Arabica beans are known for their smooth and complex flavor profiles, which often feature a range of subtle notes and lower caffeine content. They are preferred in specialty coffee for their high quality and nuanced taste. On the other hand, Robusta beans are stronger and have a more bitter flavor, with a higher caffeine content, making them less common in high-end coffee offerings but still used in blends for added body and crema in espresso.

Starbucks primarily sources Arabica beans for its range of coffees due to their flavor qualities that align with the brand's commitment to delivering premium coffee experiences. Robusta is occasionally used, particularly in some espresso blends, but Arabica remains the predominant type in their offerings to ensure a consistent and enjoyable flavor for customers. This combination highlights Starbucks' focus on quality while also catering to different flavor preferences.
