Nose is really spiced caramel in a beautiful way. Big cinnamon cherry vanilla BT Mashbill #1 bomb but then moves into a more bitter/tannic oak that keeps it from being a 5/5 however its still in the upper tier of bourbon period. I think 15y3mo might be a little too long to have aged this and that if this was at 12y it’d be perfect. Does drink under its proof. Overall incredible
