Qianjie-introduction of three major coffee bean varieties

There are about 40 species of coffee plants, but the only ones that can produce coffee beans of commercial value are Arabica, Robusta and Liberian. these three species are called the "three native species of coffee".

Arabica coffee accounts for 75%-80%. Its excellent flavor and aroma make it the only coffee that can be drunk directly among these native species. However, its resistance to dryness, frost, diseases and insect pests is too low, especially the natural enemy of coffee-leaf rust, so the producing countries are committed to variety improvement.

Arabica coffee beans are mainly grown in South America (except parts of Argentina and Brazil), Central America, Africa (Kenya, Ethiopia and other places, mainly East African countries), Asia (including parts of Yemen, India and Papua New Guinea).

The leaf rust-resistant varieties found in Congo in Africa have stronger disease resistance than Arabica. People like to compare the robusta species to the Arabica species of coffee. In fact, the robusta species was originally a mutant of the Congolese species (scientific name Coffea canephora), so it is the Congolese species that should be compared with the Arabica species. To this day, however, the name of the Robusta species is commonly used by the public, and it is regarded as the same species as the Congolese species.

Arabica coffee beans grow at colder tropical high elevations, and the hot and humid zone that is not suitable for Arabica coffee is where robusta coffee grows. Robusta has a unique aroma (called "Rob smell", which some people think is moldy) and bitterness, accounting for only 2%-3% of mixed coffee, and the whole cup of coffee becomes Robsta flavor. Its flavor is so bright and strong, in addition to instant coffee, but also commonly used in semantic matching beans.

West Africa, the origin of coffee grown in Liberia, has a strong adaptability to all kinds of environments, such as high or low temperature, humidity or dryness, except that it is not resistant to leaf rust and its flavor is worse than that of Arabica, so it is only traded or planted in some West African countries (Libya, C ô te d'Ivoire, etc.).

About 65% of the coffee in circulation in the world market is Arabica and 35% is Robusta. Arabica species are characterized by slender and flat grains, while robusta coffee beans are more round and can be easily distinguished by their shape.

Knowledge: coffee production areas in the world are mainly distributed in the south and north of the equator, also known as the "coffee belt"
