A pub is a drinking establishment licensed to serve alcoholic drinks for consumption on the premises. The term first appeared in the late 17th century, to differentiate private houses from those open to the public as alehouses, taverns and inns. Today, there is no strict definition, but CAMRA states a pub has four characteristics:is open to the public without membership or residency serves draught beer or cider without requiring food be consumed has at least one indoor area not laid out for meals allows drinks to be bought at a bar

An alcoholic beverage is a drink that contains ethanol, a type of alcohol and is produced by fermentation of grains, fruits, or other sources of sugar. The consumption of alcoholic drinks, often referred to as "drinking", plays an important social role in many cultures. Alcoholic drinks are typically divided into three classes—beers, wines, and spirits—and typically their alcohol content is between 3% and 50%.
