Sour beers, you are probably thinking (Yuck), why the hell would you want to drink a beer that tastes sour. In general, if you went into a bar and purchased a pint of cask ale, then you started drinking it and it tasted sour, more than likely you’ll reappear back up to the bar and say ‘the beers off’.
The fact is, sour beers are never found in Cask Ales, but on the other hand, many craft beers are produced in a sour way, the next question you are probably wondering is why. Well, in the history section you will find out!
