Ooh, interesting. The rancio is apparent even in the nose, although the rest of the nose is overwhelmed by alcohol (despite only 41% ABV!). There may be some maple syrup hiding in there. On the palate is a light, gentle tingle that gradually concentrates into viscous vanilla - elegant, though, not overpowering. Somehow it maintains a texture that is both thick and light. The finish evaporates sends oak right up the nose but maintains the mouth tingle with no fire down the throat. Truly quite interesting.
