For your better understand on the difference between two species of coffee beans (Arabica and Robusta), Meal Zense provides you the summary:
Flavor: Arabica beans are generally considered to have a more complex and nuanced flavor profile than Robusta beans. Arabica beans can have a range of flavors including fruity, floral, and nutty notes. Robusta beans, on the other hand, are often described as tasting more bitter and earthy.
Caffeine content: Robusta beans (Around between 2% and 4.5%) typically have more caffeine than Arabica beans (Around between 1% and 1.8%). This higher caffeine content is one reason why Robusta beans are often used in espresso blends, as espresso requires a higher concentration of coffee per serving.
Growing conditions: Arabica beans are more delicate and require specific growing conditions, such as high altitude (between 800m and 2000m) and a temperate climate with consistent rainfall. Robusta beans, on the other hand, are hardier and can be grown at lower altitudes (Up to 800m) and in warmer climates.
Price: Arabica beans generally command a higher price than Robusta beans due to their perceived higher quality and more complex flavor profile.
Overall, the choice between Arabica and Robusta beans comes down to personal preference and the intended use of the coffee. Some people prefer the stronger flavor and higher caffeine content of Robusta beans, while others prefer the more nuanced flavor of Arabica beans.
