Coffee Cup

Depending on the degree of roasting, coffee is a brown to black, psychotropic, diuretic, caffeinated beverage made from roasted and ground coffee beans, the seeds of the fruit of the coffee plant, and hot water. The degree of roasting and grinding varies depending on the method of preparation. Coffee contains the vitamin niacin.

The term "bean coffee" does not mean that the coffee is still unground, but refers to the purity of the product and serves to distinguish it from substitute coffee (made from chicory, barley malt, etc.). Coffee is a stimulant. Coffee beans are obtained from drupes of various plant species in the Rubiaceae family. The two most important species of coffee plant are Coffea arabica (Arabica coffee) and Coffea canephora (Robusta coffee) with many varieties and cultivars. There are different levels of quality depending on the variety and where it is grown.
