The best type of coffee for espresso is one that has a rich and strong flavor profile, with a balanced acidity and sweetness. Generally, coffee beans that are used for espresso are roasted to a darker roast level to bring out the full flavor and aroma. Some of the most common types of coffee beans used for espresso include:
Arabica: Arabica beans are known for their mild, fruity, and slightly acidic flavor. They are often blended with other types of coffee beans to create a well-balanced espresso.
Robusta: Robusta beans are known for their strong, bitter flavor and high caffeine content. They are often used in blends to add depth and crema to the espresso.
Blends: Many espresso blends are a combination of Arabica and Robusta beans, with varying proportions depending on the desired flavor profile. Blends are often crafted to produce a unique taste that sets them apart from single-origin coffees.
Ultimately, the best type of coffee for espresso is one that you enjoy the taste of. Experiment with different types of beans and blends to find the one that suits your taste preferences.
