Cask Conditioning

Cask conditioned beer refers to unfiltered and unpasteurized beer that has been conditioned in and served from a cask. This method will impart a distinctive flavor. Cask conditioned beer is naturally fermented and is typically served from the cask using a beer engine or hand-powered style pump as opposed to pushed using a CO2 tank. Cask beers tend to be served with lower levels of dissolved CO2 than one might find in a typical kegged beer. The shelf life of a casked beer is also much shorter, and the potential for oxidization is much higher since the cask walls are air permeable.
