Measured at half a barrel, beer kegs are used to carry, store and serve beer. How many gallons does a keg normally hold?
Answer 15.5 gallons
Due to the lack of standardization in keg sizes, the keg cannot be used as a unit of measurement for liquid quantities. Despite this, some individuals continue to refer to kegs as a unit of measurement, with a conventional one with a single aperture at the top holding 15.5 U.S. gallons.
