Very interesting! I don't tend to like higher rye mashbills, especially at a higher proof. But I like this. There's copious amounts of ethenol on the nose and palate, but it never overwhelmes. Fruits and cinnamon on both the nose and palate as well. The finish is perhaps the most unusual aspect to me - I consistently get a long and strong peanut butter note that fades in and out with some vanilla. There are obviously plenty of other cask strength bourbons out there, but I have yet to try one quite like the 1920
