Very woody. Cream. Recalls an SMWS bottling - perhaps 50.102, but not 100% sure. The delicate interplay of wood, cream, and old malt is wonderful.
A second nosing shows more as old/expensive Bourbon - either a Barterhouse or Parker's Heritage were the first points of reference to surface.
The more I nosed it, the more it trended towards Bourbon (must have been an active cask), particularly older/more heavily oaked Bourbons.
Follows the nose at first with a Bourbon lead. But subtler. Also plenty of spice. Cinnamon. Maybe some cola. The malt notes and malt complexity grow if I chew the dram: malt, golden raisin, and a slight rubbery note.
At first, a brief tartness - almost like Shock Tarts. This only came up on the first sip.
Subsequently: Bourbon, wood, vanilla, cream. The faint rubberiness from the palate reappears, again mildly. Turns grassy and vegetal in its dying notes.
