Roots of Coffee

Coffee is produced from coffee-beans, which grow on the coffee-tree resp.  coffee-bush (Coffea). It belongs to the genus of madder-plants and originally only flourished in tropical Africa. For Mathias Bödding Africa is “the cradle of mankind and of coffee.“ Today coffee, a plant of several phyla, is cultivated in two types, as Coffea arabica and as Coffea canephora. Because of its special hardiness and resistance Coffea canephora also bears the name of Coffea robusta or simply Robusta. Robusta only was discovered relatively late at the end of 19th century in Congo or Uganda and “in the meantime forms about 30 percent of world-production” [1]. Besides numerous flavourings “the roasted coffee-bean mainly contains carbohydrates, proteins, mineral compounds, fats, acids like the antiviral chlorine gen-acid and of course the alcaloid caffeine“ [1]. Besides tannic acid you also find “an ethereal oil of strange odour” [13] in the coffee-bean. Since the 19th century the main producing areas of coffee are in Southern and Middle America.
