In fact, cask ale comes in many forms, from a low strength Mild of around 3.2 per cent alcohol by volume, a Bitter of 3.5 to 3.8 per cent, a Best or Special Bitter of 4 to 4.5 per cent, an Extra Special Bitter of 5 per cent or more, and then more powerful Old Ales, Barley Wines and Winter Warmers that can reach as high as 10 or 11 per cent.
