Firkin Kegs


Peter B’s Black IPA Firkin Keg with Masterbrewer Kevin Clark

One of the best things to come out of the Craft Beer movement is the new and innovative brewing methods and equipment that have come into use. Many brewers and breweries will refer to a Firkin Keg in their literature. The term Firkin is actually an old Dutch unit of measurement, about ten gallons. Consequently, it is that measurement that refers to the Firkin Keg, which was an old wooden cask that ale used to be stored in. It holds about the same amount as a modern “pony keg”, but has a rounded shape that permits the flavor rich sediment to collect at the bottom without allowing it to escape the tap. Many beer aficionados and brewers refer to this as cask ale or cask beer when it is served directly from this specialized keg.

Peter B’s Brewpub Master Brewer Kevin Clark further describes the use of the Firkin Keg. “Most larger batches of beer are force carbonated. A brewer will inject the batch to bring it to a certain level of carbonation. A cask ale or lager is naturally carbonated as the cask or keg is filled directly from the fermenting vessel. The yeast is still alive and active and continues to consume the additional sugar added to the cask thereby creating my natural carbonation. This creates a very special beer that is conditioned to be smooth and gentle.”
