Cask strength (also known as barrel proof) is a term used in whisky-making to describe the strength of whisky in the cask during maturation. Whisky at cask strength isn't as drinkable as diluted whisky. Most bottled whisky is diluted with water to bring its strength (abv) down to a level that makes it less expensive to produce and more palatable, usually about 40% abv – which is the statutory minimum in some countries. The degree of dilution is said to bring out different flavours of the whisky, which can affect the decisions of the producers regarding the concentration they select for the bottling of their various brands.
