Really sweet vanilin coming in on the nose, some toasted almond, seems just a bit dusty as of very old oak. Amazingly pure and free of any ethanol notes for a 100 proof. The early front really springs the toasted oat/almond in a bursting sensation, following come middle sweet notes with a flash of sweet corn bread then burnt butter toast. This menage a troi of notes hangs on for the duration, you can get up walk out for a smoke and you will still have it as a reminder when you come back in. The sugars are a bit sparse comprised mostly of vanilla and feint caramel. I would be remiss not to mention the almost Bartons level of old oak mustiness trailing at the finish that reminds us this is indeed a well aged oak barrel product. All of that and an incredible smooth ending and the burnt almond butter cracker that lasts forever. Hard to get but well worth it.
