Are there different species of coffee besides Arabica and Robusta?

The common perception that coffee is a binary choice between Arabica and Robusta is a commercial construct, not a botanical reality. The Coffea genus is remarkably diverse, comprising at least 131 distinct species. Arabica and Robusta have achieved global hegemony primarily due to their yield, processing stability, and established market infrastructure. However, this narrow focus creates a systemic vulnerability; Arabica, in particular, is highly sensitive to climate shifts and disease. For the producer, the reliance on these two species is often a matter of market access rather than agronomic preference. Farmers in regions like South India or parts of West Africa have long cultivated species such as Liberica and Excelsa, which are often better adapted to local microclimates and pests. The current industry shift toward 'fine' Robusta and the exploration of species like Stenophylla—which has shown potential for high-quality cup profiles at higher temperatures—represents a necessary pivot toward biodiversity. The misconception that only Arabica can produce 'quality' coffee is being dismantled by producers who apply specialty-grade processing techniques to these alternative species. By diversifying beyond the two dominant species, the industry is not just seeking new flavors; it is attempting to secure the future of coffee farming against a changing climate that threatens the viability of traditional Arabica crops.
