N: Some alluring notes here under the expected alcohol prickle (it is 60.5% after all). Takes a long, long time to open up at full strength. Eventually I got some hot-buttered toast, malt loaf, raisins. Develops some very nutty aromas - hazelnut, almond, walnut whips. Old seasoned wood - more than you'd expect for a whisky of such relative youth.
N with water: Much more genial and approachable, naturally. Strong notes of polished wood, and waves of very clean malt, with a hint of briar / berries. Again, more noticeable wood influence than expected.
P: Big nuttiness to the fore, but again, at full strength the alcohol is almost too much to handle. This definitely needs a drop or two of water.
(With water): Woody and peppery, with dried apricots, lingering spices, nuts and a hint of tweed.
F: Pretty hot at full strength. Water tames it but it remains very long, with hot, lingering chilli pepper and woody spices.
C: A real curio. For a young whisky it seems both very heavily-wood influenced and also quite old-fashioned in style. Certainly if tasted blind I'd have made a fool of myself - I'd never have picked this as Japanese, and probably would have guessed it as a 15-18 yrs old Highlander. Definitely needs water.
