Cask and keg sizes can vary depending on the region and brewery. In the United Kingdom, casks are typically referred to as “firkins” and come in various sizes, with the most common being the “9-gallon cask” or “firkin.” This cask holds approximately 72 pints or 41 liters of beer. There are also smaller cask sizes such as the “4.5-gallon pin” or “kilderkin,” which holds around 36 pints or 20.5 liters.
Keg sizes, on the other hand, are more standardized and commonly used in the United States and other countries. The most common keg size is the “half-barrel” or “full-size keg,” which holds about 15.5 gallons or 124 pints of beer. This is equivalent to approximately 58.7 liters. Other keg sizes include the “quarter-barrel” or “pony keg,” which holds around 7.75 gallons or 62 pints, and the “sixth-barrel” or “corny keg,” which holds about 5 gallons or 40 pints.
It's worth noting that these sizes can vary slightly between different breweries and regions. Some breweries may also use different names for their cask and keg sizes. It's always best to check with the specific brewery or supplier to confirm the exact size and volume of their casks and kegs.
Personally, as a sommelier and brewer, I have worked with various cask and keg sizes throughout my career. It's important to consider the size of the vessel when planning production and distribution, as it can impact the quantity of beer available and the shelf life of the product. Smaller casks and kegs are often preferred for limited releases or specialty beers, while larger sizes are more commonly used for regular production and distribution.
Casks and kegs come in different sizes depending on the region and brewery. The most common cask size is the 9-gallon or firkin, while keg sizes range from half-barrels to smaller options like quarter-barrels and sixth-barrels. It's essential to consider the size and volume of casks and kegs when planning production and distribution strategies for different types of beer.
