Robusta coffee is another species of coffee that is native to Africa, specifically the Congo and Uganda. It was first discovered in the central and west Africa in the late 19th century. People originally thought Robusta coffee could be a lower quality level coffee after Arabica, but due to its high caffeine content and bitter favor profile. Robusta has become the second largest coffee production after Arabica.
Since Robusta is more disease-resistant than Arabica coffee and low growing altitude requirement, it is easier to cultivate in certain regions and become an important trading business of countries in Southeast Asia.
The popularity of Robusta coffee has fluctuated over the years, with demand often tied to the price of Arabica coffee. When Arabica coffee prices are high, roasters and manufacturers may turn to Robusta coffee as a cheaper alternative. However, in recent years, Robusta coffee has gained a following among specialty coffee enthusiasts who appreciate its unique flavor profile and caffeine kick.
