What defines a real ale or cask ale?

Real ale or cask ale is a type of beer that is served from a cask without additional nitrogen or carbon dioxide pressure. The term “real ale” is mainly used in the UK, while “cask ale” is used more widely around the world.

Real ale is typically brewed using traditional methods and ingredients, such as malted barley, hops, yeast, and water. It is left to ferment in the cask, where the yeast converts the sugars into alcohol and carbon dioxide. This natural carbonation process produces a relatively low level of carbonation, giving the beer a softer, smoother mouthfeel and a creamier head than beers that are carbonated with added gas.

Real ale is typically served at cellar temperature (between 11 and 13 degrees Celsius), which allows the full range of flavours and aromas to come through. It is often hand-pulled using a beer engine, which creates a gentle flow of beer and allows the drinker to appreciate the full character of the beer.

The Campaign for Real Ale (CAMRA), a UK-based consumer organisation, is a major advocate for real ale and has established standards for what can be considered a “real ale.” According to CAMRA, real ale must be unpasteurised, unfiltered, and brewed using only natural ingredients. It must also be served without the use of additional gas pressure and should undergo secondary fermentation in the cask.
