The cask proof version of our ever-popular Roundstone Rye is a very special expression. Released at approximately 58% ABV (it varies depending on the individual barrels), this is seriously strong whisky! Delicious, dark, complex and ridiculously smooth for the proof, Roundstone Rye is only released about twice a year. Keep informed of product releases by subscribing to our newsletter. Cask proof releases will be announced about a month in advance.
