Nose of vanilla and toasted oak. In the mouth it is vanilla and a bit of maple then a pepper attack on the backside... nice, but I am not sure it is any better than the reg 9 year. Need to come back to this and maybe do an a vs b between them. PS did an A/B and the single barrel is slightly better, similar profiles but more intense (in flavors as well as proof). Oddly the nose is lighter than the standard knob... 🤷🏼‍♂️
