A special edition release of Johnnie Walker, this 21 year old expression was inspired by the blending notes of Sir Alexander Walker. Alexander Walker II was a master blender like his father and his grandfather before him, who devoted his life to making exceptional whiskies. John Walker & Sons XR 21 was created to honour this very special occasion. Inspired by Sir Alexander’s own hand-written notes, it is blended from the exclusive Johnnie Walker reserve of rare whiskies, all of which have been matured for a full 21 years. 40% alc./vol.
