What name is given to the cask, which holds a quarter of a barrel of beer?
English brewery cask units For CAMRA internal accounting, all are calculated in kilderkins. A kilderkin is a 144 pint container but there is not 144 pints of cask conditioned consumable beer in a kilderkin (see Firkins below for explaination). The ale or beer firkin (from Middle Dutch meaning "fourth") is a quarter of an ale or beer barrel or half a kilderkin. This unit is much smaller than the wine firkin. Casks in this size (themselves called firkins) are the most common container for cask ale. A pin is equal to half a firkin (). Plastic versions of these casks are known as "polypins"
Cask ale Cask ale Cask ale or cask-conditioned beer is unfiltered and unpasteurised beer which is conditioned (including secondary fermentation) and served from a cask without additional nitrogen or carbon dioxide pressure. Cask ale is also sometimes referred to as real ale in the United Kingdom, a term coined by the Campaign for Real Ale (CAMRA), often now extended to cover bottle-conditioned beer as well. Cask or barrel is a container. The Histories of Herodotus, written in 424 BC, refers to "casks of palm-wood filled with wine" being moved by boat to Babylon, though clay vessels would also have been used. Stout
