A beer engine is a hand pump for pumping beer from a Cask. At Growlers Pour House, we use an antique 1936 Gaskell & Chambers beer engine to bring back this centuries-old pub tradition.
The beauty of cask-conditioned ales is their unfiltered, unpasteurized nature. These ales are naturally-yeast-carbonated through not one, but two rounds, of fermentation. When the yeast finish their work for the second time, the beer is left with a very light natural carbonation and a subtle depth of flavor. It's then pulled up to the glass by the force of a hand pump, rather than by the force of a CO2 tank. Don't be fooled by the warmer temperature - Cask ales are best enjoyed gently chilled at cellar temperatures.
