For decades Johnnie Walker has been the best-selling Scotch whisky in the world. The brand has been a fixture in many of the best bars in the world, and now shows it is not afraid to experiment. Johnnie Walker Bourbon Cask & RYE Finish is a bold experiment in flavor. It was created from experiments using more than 200 whisky samples. The final blend features whiskies from five distilleries, including Dufftown and the now closed Port Dundas. Johnnie Walker Bourbon Cask & RYE Finish has aged in former bourbon casks, before enjoying a finish for up to 6 months in rye casks. The result is remarkable.
