Beer

Beer is one of the oldest and most widely consumed alcoholic drinks in the world, and the third most popular drink overall after water and tea. Beer is brewed from cereal grains - most commonly from malted barley, though wheat, maize (corn) and oats are also used. During the brewing process, fermentation of the sugars in the wort produces ethanol and carbonation resulting in beer. Most beer is brewed with hops, which adds bitterness and acts as a natural preservative. Beer is distributed in bottles and cans and is also commonly available on draught in pubs and bars. When beer is distilled, the resulting liquor is a form of whisky.

Etymology
The word "beer" comes from Middle English bere which is from Old English beor which is descended from Proto-Germanic beuzą which is perhaps from Proto-Indo-European bʰeusóm meaning "brewer's yeast, beer dregs". Alternatively, the Chuvash word for beer "pora" with its r-Turkic counterpart, may ultimately be the source of the Germanic beer-word.
