Beer

Beer is the world's oldest and most widely consumed alcoholic beverage and the third most popular drink overall after water and tea. It is produced by the brewing and fermentation of starches which are mainly derived from cereal grains — most commonly malted barley although wheat, maize (corn), and rice are also used. The alcoholic strength of beer is usually 4% to 6% alcohol by volume (ABV), but it may be less than 1% or more than 20%
