"Cask ale" refers to a traditional type of beer that is served directly from the cask or barrel where it has undergone fermentation and conditioning. Also known as "real ale," this type of beer is unfiltered and undergoes a secondary fermentation in the cask, which allows for natural carbonation through the release of carbon dioxide.
Cask ale is distinct from other types of beer as it is not pasteurized, meaning it does not undergo heat treatment to extend its shelf life. Instead, it matures and develops its flavors inside the cask, providing a unique taste and texture. The process of serving cask ale involves manually drawing the beer using a hand-operated pump, or by gravity, directly from the cask, without any additional artificial carbonation or pressurization.
The use of a cask allows the beer to be both fermented and served at a slightly warmer temperature compared to other beers, typically between 50-55°F (10-13°C). This warmer serving temperature enhances the flavor profile and aroma of the beer, providing a more complex and nuanced drinking experience.
Cask ale is known for its natural, smooth, and low carbonation, with a rich and fuller body. It often exhibits a range of flavors, including hints of fruit, malt, hops, and yeast, which can vary depending on the type of beer and ingredients used.
Cask ale, with its traditional brewing and serving methods, is highly valued by beer enthusiasts, who appreciate its unique characteristics and support the preservation of this authentic brewing tradition.
