Really nice, complex nose, despite the high alcohol content.
Without water: bitter oak, tannins, bit of smoke, tiniest hint of brine. Very spicy, with a gradually building finish that peaks nicely then fades. Slightly disappointing after the tremendous nose.
With water:much more soft vanilla in the nose. Tones down the bitterness of the burnt wood very much. It's actually almost enjoyable to drink now. Still quite a bitter aftertaste though, and the spicy finish (the only enjoyable part of the taste without water is gone).
