This bottle has been open for about a month now, but hasn't changed dramatically. The nose is stronger than expected from a 90 proofer. Sweet caramel and butterscotch, but definitely some heat in there. Palate is nice and smooth with some fruity notes added to the caramel from the nose. Thankfully, the heat from the nose didn't carry through. Finish is a little lacking, but it's hard to complain for a $23, 90 proof bourbon.
