Coffee is a black drink made from roasted and ground coffee beans, which come from the fruit of coffee plants in the genus Coffea. There are two major varieties: Coffea arabica from Ethiopia and Coffea canephora. Arabica is the most appreciated and cultivated type, originating from Ethiopia where coffee plants were first discovered in the Kaffa region and introduced to the Arab world. Instant coffee was first obtained in 1890 by David Strang using a dry process.
