Beer Barrel

A beer barrel, also known as a beer cask or keg, is a container used to store and serve large quantities of beer. Traditionally made of wood or metal, it typically holds about 31 gallons (117 liters), though sizes can vary. Beer barrels are used in breweries for fermentation, aging, or transportation, and in bars or events for serving beer directly from the barrel through taps. They allow for fresher, preservable beer and are an essential part of traditional brewing and beer dispensing methods.
