What are the main species of coffee beans?
The two primary species of coffee beans are Coffea arabica and Coffea canephora, commonly known as Robusta. Arabica beans account for about 60-70% of the world’s coffee production and are known for their smooth and complex flavor profile. They thrive in higher altitudes and are generally grown in regions with cooler temperatures, which contribute to their sought-after taste qualities.
Robusta beans, on the other hand, are hardier and can withstand more varied growing conditions, including lower altitudes and higher temperatures. They have a stronger, more bitter flavor compared to arabica beans and contain higher levels of caffeine. This species is often used in instant coffee and espresso blends due to its bold attributes and ability to create a rich crema.
Are there more coffee species apart from Arabica and Robusta?
Yes, aside from the well-known arabica and robusta species, there are over 100 other identified coffee species. However, the majority of the global coffee market relies heavily on arabica and robusta due to their favorable flavor profiles and suitable growing conditions. Some lesser-known species include Coffea liberica and Coffea excelsa, both of which have distinct taste characteristics.
Coffea liberica is grown primarily in West Africa and has a unique, woody flavor and an aromatic profile that is quite different from both arabica and robusta.
