Cask conditioned beer is a delicate product and, just like the beer undergoing fermentation in the brewery, it is vulnerable to attack from all kinds of contamination by wild yeasts and other micro-biological organisms. Other beers are bought to condition in the brewery, some are fined and filtered and some are pasteurised to guard against deterioration from microbes. They reach the consumer in casks, kegs, bottles or cans. For lagers there is a longer period of conditioning in the brewery at low temperature. The word lager comes from the German word lagern - to store at a cold temperature.
