Coffee plant in the context of "Rubiaceae"

Coffee production is the industrial process of converting the raw fruit (the coffee cherry) of the coffee plant into finished coffee beans. About eight months after coffee cherries appear on a coffee plant, the cherries are harvested either by hand or by machine. Then they are, depending on the method, pulped and then dried or simply set out to dry. After this, the beans are stripped of their remaining dry skin and fruit residue. Once they are cleaned, sorted, and graded, they are suitable for distribution. While all green coffee, produced from immature coffee beans, is processed, the method that is used to process coffee varies, and significantly affects the flavor of coffee once it is roasted and brewed. Coffee production is a major source of income for 12.5 million households, most in developing countries.

Coffea canephora (especially C. canephora var. robusta, so predominantly cultivated that it is often simply termed Coffea robusta, or commonly robusta coffee) is a species of coffee plant that has its origins in central and western sub-Saharan Africa. It is a species of flowering plant in the family Rubiaceae. Though widely known as Coffea robusta, the plant is scientifically identified as Coffea canephora, which has two main varieties, robusta and nganda.

Coffea robusta represents between 40% and 45% of global coffee production, with Coffea arabica constituting most of the remainder. There are several differences between the composition of coffee beans from C. arabica and C. robusta. Beans from C. robusta tend to have lower acidity, more bitterness, and a more woody and less fruity flavor compared to C. arabica beans. Most of it is used for instant coffee.
