、. Robsta species (scientific name Coffea robusta Linden)
Varieties resistant to leaf rust found in Congo, Africa, teach Arabica species to be more resistant to the disease. 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 Cofffea 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% of mixed coffee. 3%, the whole cup of coffee becomes Robusta flavor. Its flavor is so bright and strong that if you want to taste it directly, you have to consider it. It is generally used in instant coffee (which extracts about twice as much liquid coffee as Arabica), bottled coffee, liquid coffee and other industrial coffee. The content of caffeine is about 3.2%, much higher than 1.5% of Arabica species.
The main producers of Robusta species are Indonesia, Vietnam and West African countries centered around C ô te d'Ivoire, Algeria and Angola. In recent years, Vietnam has made more efforts to become one of the major coffee producing countries. Coffee production is also included in national policy (Vietnam also produces some Arabica coffee).
, Liberian species (scientific name Coffea liberica)
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.).
