BEANS & SPECIES

Are there more than two species of coffee?

Quick answer

Yes, there are over 120 known species of coffee in the Coffea genus. While Arabica and Robusta dominate the global market, other species like Liberica and Excelsa are cultivated for their unique flavor profiles. Many other species exist in the wild, though they are rarely used for commercial coffee production due to low yields or poor flavor.

The real story

While the average consumer is familiar only with Arabica and Robusta, the botanical reality of the coffee plant is far more diverse. The Coffea genus contains over 120 distinct species, all of which are native to tropical regions of Africa, Asia, and the islands of the Indian Ocean. These species range from small shrubs to large trees, each adapted to specific microclimates and environmental pressures.

Arabica (Coffea arabica) and Robusta (Coffea canephora) are the only two species that have achieved massive commercial success. Arabica is favored for its superior flavor and complexity, while Robusta is valued for its resilience and high yield. However, other species have carved out small, specialized niches. Liberica (Coffea liberica), for instance, is known for its large, irregular beans and a bold, smoky, and floral flavor that is highly prized in certain regions of Southeast Asia.

Excelsa, which was once considered a separate species but is now often classified as a variety of Liberica, is another notable example. It is known for its tart, fruity, and complex profile, often used in blends to add depth. Other species, such as Coffea stenophylla, have recently gained attention from researchers and specialty roasters for their potential to offer high-quality flavor profiles while potentially being more resilient to climate change than Arabica.

Most of the other 100+ species remain in the wild, serving as a vital genetic reservoir. This genetic diversity is crucial for the future of the coffee industry, especially as climate change threatens the viability of current Arabica crops. Scientists are actively studying these wild species to identify traits like drought resistance, disease tolerance, and unique flavor compounds that could be bred into future coffee varieties.

In practice, this means that the world of coffee is much larger than the two options on your grocery store shelf. As the specialty coffee movement continues to grow, we are likely to see more 'rare' species and varieties appearing in cafes, offering consumers a chance to explore the incredible botanical diversity of the coffee plant beyond the standard Arabica and Robusta.
