Glennfiddich is the devils piss (even the scots dont drink it).....having a rare bottle is cool but nearly blasphemy to call it the stanley cup(both to the cup and scotch) :). Honestly anything over 18 years I find is not as good as 12-18yr bottles. I think that is the scotch sweetspot, my 40yr is neat tasting, very sherry like and completely unique but not something i would enjoy to sit down with at night.
Anyway cool topics!
