Robusta is one of the most important varieties of coffee in the world.

Robusta species (scientific name Coffee Robusta Linden) is one of the most important coffee tree varieties in the world. The leaf rust-resistant varieties found in Congo in Africa have stronger disease resistance than Arabica.

Brief introduction

In the general coffee market, many people like to compare robusta and Arabica coffee beans, which is incorrect. In fact, the Robusta species was originally a mutant of the Congo species (scientific name: Coffee Canephora), and it should be compared with the Alabica species. Today, however, the Robusta species is commonly used by ordinary people, and it is not known that it is actually a variant of the Congolese species.

Growth and environment

Arabica coffee beans grow at colder high elevations in the tropics, and those high temperatures and low elevations that are not suitable for Arabica are the land of Robusta. Robstado grows in the lowlands at 200-600m above sea level and likes warm climates. the temperature is 24-29 ℃, and the requirement for rainfall is not high. However, the variety depends on insects or wind to pollinate, so it takes 11 months from pollination to fruit, which is longer than the Arabica species.

Characteristics.

The coffee tree planted by Robusta is a kind of tree between shrubs and tall trees. Its leaves are long and bright green. The tree can be up to 10 meters high, but its roots are very shallow. The fruit is slightly rounder and smaller than Arabica coffee. The bean body is flat and round. The middle pit is straight. Robusta kind of Ken has a unique aroma (known as "Rob flavor", some people mainly moldy smell) and bitter taste. If 23% of the coffee is mixed with other coffee, the whole cup of coffee will become Rob flavor (therefore, Robusta coffee beans can not be drunk as individual coffee beans). Its flavor is so bright and strong, but if you want to taste it directly, you have to be prepared. In general, robusta coffee is used in instant coffee (which extracts about twice as much liquid as Arabica), canned coffee, liquid coffee and other industrial coffees. Its caffeine content is much higher than that of Arabica, about 3.2%.

Current situation of development

The output of Robusta species accounts for 25% of coffee bean production, which accounts for 25% of coffee bean production. Its main producing country is Indonesia (one of its coffee beans is a kind of coffee bean processed by washing method, which is a hybrid between Robusta and Arabica. It is the only coffee bean on the Chinese market that can be used as a single drink), Vietnam, Africa, (Ivory Coast, Nigeria, Angola as the center of the West African countries), Vietnam has been more committed to coffee production in recent years, and included it in the national policy (Vietnam also produces a small number of Arabica coffee beans).
