A cylindrical container, usually constructed of steel or sometimes aluminum, commonly used to store, transport and serve beer under pressure. In the U.S., kegs are referred to by the portion of a barrel they represent, for example, a ½ barrel keg = 15.5 gal, a ¼ barrel keg = 7.75 gal, a 1/6 barrel keg = 5.23 gal. Other standard keg sizes will be found in other countries.
