I always question "bourbon cask" finished as a feature of any whisky as most Scotch and Irish is matured in Bourbon casks. It is like saying a "metal car" or a "terrible Brexit plan"; it's a bit redundant. Bushmills have highlghted the #3 char of oak casks used (meaning a few seconds less exposure to fire than the more common #4) as the USP of this expression. The nose is malty with banana, vanilla and milk chocolate. The taste also has malt and nuts, lemon citrus peel and sweet peanut brittle. The finish is initially sugar coating on tongue with a spicy note of cinnamon and tamale hots candy at the end. At end of the day it is another bourbon cask finished whisky and there is not much here that stands out so if you are in mood for no-age expression Bushmills (and why not) I would probably recommend Black Bush over this one.
