Coffee,common name for any of a genus of trees of the madder family,and also for their seeds (beans)and for the beverage brewed from them.Of the 30or more species of the genus,only three are important:Arabian,robusta,and Liberian.The shrub or small tree,4.6to 6m (15to 20ft)high at maturity,bears shiny green,ovate leaves that persist for three to five years and white,fragrant flowers that bloom for only a few days.During the six or seven months after appearance of the flower,the fruit develops,changing from light green to red and,ultimately,when fully ripe and ready for picking,to deep crimson.The mature fruit,which resembles a cherry,grows in clusters attached to the limb by very short stems,and it usually contains two seeds,or beans,surrounded by a sweet pulp.

Coffee grows well on the islands of Java and Sumatra and in Arabia,India,Africa,the West Indies,and South and Central America.The Americas,where Arabian coffee is grown,produce approximately two-thirds of the world's supply.
