The nose reflects the 58.5% ABV; at first the immediate sharp prick of alcohol and then with a little time (and caution) in second place there are a few traditional bourbon notes. The mouth feel is sharp and spiky as well, with sweet notes, then orange peel, vanilla toffee and some tobacco. The finish is spicy with chilli and burnt sugar. Water helps smooth feel but also brings some the bitter oaky notes as well as bringing out more spices like cinnamon and pepper. Not a bourbon for beginners.  As is often the case with barrel and cask strength whiskies, it is too much, it is like bringng a gun to a knife fight.
