Cask strength whisky

A cask strength whisky is bottled at the strength it came from the cask, rather than reduced with water to a standard strength. Its ABV can therefore vary between batches, and the label states the batch strength. This page lists cask-strength bottles in stock at the UK retailers we check, including Arran, Highland Park, Glenfarclas, GlenAllachie, Maker’s Mark and Indri.

Adding water to taste is normal. Cask strength does not mean single cask, and these whiskies are usually non-chill-filtered rather than always so.

For the bottling process, see Whiskipedia on cask strength whisky. Prices are the best current in-stock offer from the UK retailers we check (how we compare prices).

Questions

Should I add water to cask strength whisky?
Yes, if you prefer it that way. Add a little at a time and stop when it suits your taste. Producers bottle at cask strength so the drinker can decide how much water to add; there is no required amount. You can also drink it without water. Whiskipedia’s cask strength guide explains the bottling method.
Why does the strength change between batches?
Each batch is drawn from different casks, which lose water and alcohol at different rates as they mature. The resulting bottling strength therefore differs. The label states the batch’s ABV, and our listings name the batch where the retailer does. Compare the exact batch and bottle size rather than assuming two releases with the same name are identical.
Is cask strength the same as single cask?
No. Cask strength concerns dilution: the whisky has not been reduced to a standard strength with water. Single cask concerns how many casks went into the bottle. A whisky can be both, either or neither, so check both parts of the label. Our single cask whisky page lists that separate category.
