A keg is a small cask used for storing liquids. Wooden kegs made by a cooper were used to transport nails, gunpowder, and a variety of liquids. Nowadays a keg is normally constructed of stainless steel, although aluminium can be used if it is coated with plastic on the inside. It is commonly used to store, transport, and serve beer. Other alcoholic or non-alcoholic drinks, carbonated or non-carbonated, may be housed in a keg as well. Carbonated drinks are generally kept under pressure in order to maintain carbon dioxide in solution, preventing the beverage from becoming flat.
