Closed and rough even after several months of bottle oxidation. Grassy, strangely sweet vanilla. Plastic. Some kind of glue. Damp stones. Rock hard old wing gums. Immature despite his 25 years. Drinkable, absolutely, the taste has a relatively pleasant sweet malty tone but you expect more from a 25 year old Single Malt.
A side note is that it has an extreme scotch mist. With a few tablespoons of water, it becomes almost milk-like and it goes fast. That's what I take with me in memory of this bottle, not so much taste and aroma.
