I have a tiny suspicion this whisky might not have spent all its venerable over 40 years in the same cask on account of all the butterscotch in it, but I may be wrong.
Strong butterscotch/taffy at first. Blind I'd guess it's a Speyside whisky. Some time in the glass, and just a drop or two of water, help open it up and then a tropical fruitiness emerges, with a bit of butter, and mixed fruit & licorice candy (Sirkusaakkoset for you Finns). More time gives me some salty hay, caraway, and a little wisp of smoke.
Strong taffy and tropical fruit juice. It doesn't feel that complex on the tongue, but the body is admirably soft yet full, and the taste itself is satisfying, and never tiring. I'm of a mind that the cask has had a little too much influence on the spirit, even though any overt tannins etc. are missing, and the nose is IMO better than the taste, but it's hard to fault this one, really, even if it is no Auld Acquaintance.
Long, sweet and fruity. Some time and a few drops of water bring in a nice waxiness to the tail.
