What is a common type of coffee tree grown commercially?

Coffea arabica is a prevalent type of coffee tree grown commercially, accounting for approximately 60-70% of the world’s coffee production. This species is favored for its higher quality beans, complex flavors, and aromatic properties, which are highly sought after in specialty coffees. Arabica coffee trees thrive in higher altitudes and require more specific growing conditions, including cooler temperatures, shade, and higher humidity.

In comparison, Coffea canephora, commonly known as Robusta, does play a significant role in coffee production, but its beans are generally seen as lower quality with more bitter flavors compared to Arabica. Coffea robusta is often used in commercial instant coffees and espresso blends for its earthy flavor and higher caffeine content. Meanwhile, Coffea liberica is less commonly cultivated due to its unique and sometimes polarizing flavor profile, which includes woody and floral notes that are not preferred by all consumers.
