Do Single Cask & Cask Strength mean the same thing?
No. If the whisky comes from one cask only, it frequently is referred to as Single Cask. Whisky in the cask, depending on the age and the initial filling strength, can exceed 60 per cent alcohol by volume. Most whiskies are bottled between 40 per cent (the legal minimum) and 46 per cent alcohol by volume. If the whisky is not watered down, or is slightly watered down but still kept at a relatively high strength, it is frequently labeled Cask Strength. Note that Cask Strength Scotch does not have to be from a single cask, i.e. a Single Cask Scotch, nor vice versa, although this is often the case.
