nose is oaky and with a little bit of smoke. You can definitely tell from the nose that this spent 15 years in an oak cask. The oak brings with it that thick maple syrup/molasses smell. It has a sweet characteristic.
The malt is a little underwhelming on the palette. It tastes a bit thin. Whereas I would usually add a little water to a malt this age bottled above 40 % (43% to be exact) I am afraid to add any to this for fear of washing it out. There is a hint of smokiness on the back of the tongue. The finish is a little acrid/sharp and short. All in all not very impressed and I would recommend several cheaper malts with less years in the barrel but have more character before spending the bills on this one.
I don't think I can rate this more than 80/100 and that may be generous.
