Boutique Coffee explains in detail the three native species of coffee

There are about 40 species of coffee plants, but only Arabica, Robusta and Liberian species can produce coffee beans with commercial value. These three species are called "three native species of coffee" Arabica species: Arabica species The origin of the Ethiopian plateau. Arabica coffee accounts for 75%-80% of all coffee species, and its excellent flavor and aroma make it the only coffee of these native species that can be drunk directly. However, its resistance to dryness, frost pests and diseases is too low, especially the natural enemy of coffee--leaf rust. Robusta species: A leaf rust-tolerant variety found in Congo, Africa, Robusta species has a distinctive aroma (an odor called "rob," which some consider a frosty odor) and bitterness. It is commonly used in instant coffee,(It extracts coffee liquor about twice as much as Arabica.) Industrial coffee, such as canned coffee, has a caffeine content of about 3.2% higher than Arabica's 1.5%. West Africa is the origin of Liberian coffee. It has strong adaptability to various environments such as high temperature or low temperature, humidity or dryness. It is not resistant to leaf rust and its flavor is worse than Arabica. Therefore, it is only traded or planted in some West African countries for research.
