Are there more than two types of coffee beans?

When most people think of coffee, they picture the familiar binary of Arabica vs. Robusta. This is understandable, as these two species make up the vast majority of the world's coffee production. Coffea arabica is the darling of the specialty coffee world, known for its complex sugars and nuanced acidity, while Coffea canephora (Robusta) is prized for its high caffeine content, disease resistance, and thick body. However, treating these two as the only options ignores the rich, wild world of coffee botany.

The genus Coffea is incredibly diverse, with over 120 documented species discovered across Africa, Asia, and the Indian Ocean islands. Many of these species are wild plants that never made it into mass production because they were either difficult to cultivate, produced low yields, or simply did not fit the flavor expectations of the global market. Yet, in this vast genetic library lie the answers to some of the industry's biggest challenges, such as climate change and pest resistance.

For example, Coffea liberica and its related cousin, Coffea excelsa, have been consumed regionally for generations but remain rare on the global stage. These species are being rediscovered by modern breeders and specialty roasters for their bold, smoky, and floral characteristics. They represent a "third way" for consumers bored with the standard Arabica profile, providing an opportunity to experience coffee that feels entirely new.

For the curious reader, moving beyond the "big two" is a way to appreciate the sheer complexity of coffee. While you won't find 100 different species on your grocery store shelf, specialty roasters are increasingly offering limited releases of these rare beans. By trying them, you aren't just drinking a beverage; you are participating in the conservation of coffee's genetic diversity, ensuring that these unique species continue to exist for future generations.
