What type of coffee does Starbucks age?

Starbucks ages Sumatra and Sulawesi coffee to develop their distinct flavors and characteristics. The aging process involves storing the green coffee beans in a controlled environment over time, which allows for subtle changes in the flavor profile. This method can enhance the earthy notes and complex characteristics that both Sumatra and Sulawesi coffees are known for. Aging is particularly suitable for these regions' coffee due to their unique beans and processing methods that can benefit from the maturation process.

The other types of coffee mentioned, such as Arabica from Ethiopia, Robusta from Brazil, and Kona from Hawaii, are generally not subjected to aging in the same way. While they may have their own traditional processing or storage practices, they do not have the same historical or cultural context associated with aging that Sumatra and Sulawesi coffees do.
