COMPOSITION OF COFFEE

Coffee is an evergreen tropical tree and coffee beans are its seeds. A ripe coffee berry usually contains two seeds.There are two commercial varieties of coffee, Coffea arabica (arabica) and Coffea canephora (robusta), which differ from each other not only in flavour but also to some extent in their composition. In Finland, mostly arabica coffee is used. There are many kinds of coffee drinks available, and the composition of these depends on such factors as the quantity of ground coffee, the brewing method, the quality of the water used, and the other ingredients used in the coffee.
