What is a Firkin?

A firkin is a small cask (10.8 gallons) used for brewing cask-conditioned ale or what is sometimes called “real ale.” A smaller version of a firkin, known as a pin, holds 5.4 gallons. Most firkins are made of steel, but there are also wooden firkins that add the flavors of the wood to the brew as they age. These cask brews are served directly from the same container in which they were fermented.

This method of brewing is the way beer was made for thousands of years.

Cask ale (or real ale) is young beer that has been placed in small metal English casks called firkins. In the sealed firkin the beer undergoes a special conditioning process whereby the yeast produces carbonation and wonderful flavor components and then settles to the bottom of the cask. After a time, excess carbonation is vented and a serving tap is hammered into a spout on the cask. The beer is served without pasteurization or additions of artificial carbon dioxide or other gasses. This is soft, fresh, living beer the way it was meant to be served!
