Not much going on in the nose -- a little astringent, some vanilla.  So the palate is a pleasant surprise -- there's that sort of lowland-bourbon-casked-spice with quite a bit of sweetness.  At this very high ABV I can still drink it neat and enjoy it -- it's an assault in a good way.  Water brings out some grassy flavors as well.  This whisky seems to fit neatly along with some other notable spicy-high-strength Lowlanders I've tasted (Linlithgow 1982 Duncan Taylor pops to mind).  I do really enjoy this one quite a bit, both without water (for the kick-in-the-face of flavor... but it is admittedly anesthetizing) and with it (for a gentler experience).
