Introduction to the flavor characteristics of medium-grain coffee, that is, robusta coffee, compared with Arabica coffee

Robbstaddo grows in the lowlands 200-600m above sea level. He likes warm climates and requires a temperature of 24-29 ℃. The requirement for rainfall is not high. However, the variety relies on insects or wind to pollinate, so it takes 11 months for coffee from pollination to fruit, which is longer than the Arabica species. Tower species (Latin name Coffee Robusta Linden), 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.

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 has a unique aroma (known as "Rob smell", which some people think is moldy) 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%.

The Robusta species should be called the Coffea Canephora species-this original species is native to the Congo in Africa. Compared with Arabica, Robusta has the advantages of strong vitality, good resistance to diseases and insect pests and low cost of planting and management, but it is slightly inferior in flavor and aroma, so it is not recognized by coffee consumers. The height of the Robusta coffee tree is between Arabica and Liberian, and the round fruit size is also between the first two, so it is also called medium-grain coffee. Compared with Arabica, the sour taste of Robusta is not obvious, but the bitterness is often more prominent, and the coffee is more greasy at the same altitude. 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).
