Beer is most widely consumed and likely the oldest alcoholic drink in the world's. It is the third most popular drink, after water and tea.
Beer is sold in bottles and cans; it may also be available on draught, particularly in pubs and bars. The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. Beer forms part of the culture of beer-drinking nations and is associated with social traditions such as beer festivals.
