473mL can, pours a clear dark amber brown with a medium beige head. Nose is full of oak and vanilla upfront, with gentle bourbon -- no hint of the Blue Buck base underneath. Flavour is quite sweet, being mostly a function of the bourbon casks -- there's lots of oak, lots of vanilla, and some butterscotch-like sweetness. Not really that bad. The barrels are pleasant. It's just a very strange and hilarious choice for an anniversary beer. Pleasant.
