What does “Cask Strength” mean?
Before being bottled, a whisky is usually watered down to around 40-46%vol of alcohol. This is done to open up it’s taste and make it more accessible to the general public, since the distillers know at which strength most people prefer this whisky. A cask strength whisky is filled straight from the cask, without adding any water. Such a whisky can have anywhere from 42 to well over 60%vol of alcohol.
