The same would be true if it were Jack Daniels Black label.
True single cask bottlings could vary depending on the quality of the cask or casks involved.
I don't think a distllery, in this case Glenfiddich, would tamper with the method of distillation from batch to batch - just my $0.02!
I'm curious about the 12 yr that tasted like a 15yr or older?
The 15yr Glenfiddich Solera Reserve, if its this one, has usually received fairly high praise - its one I really enjoy. An additional item to remember is that the age i.e. 12 yr or 15 yr is the youngest age of a cask used in the blend not necessarily the age of all the casks.
Thanks for the excellent reply and I guess it then goes that when a master blender retires then the next one may end up making choices, for any number of reasons, which may or may not affect the overall flavor of a whisky.
I don't know what that one bottle of Glenfiddich 12 tastes like other than I was surprised to like it so well when every other experience had taught me that I didn't care for it. I do think that particular bottle is over 15 years old due to the time frame of my friends death and the different appearance of the box and label. I know none of that should affect the flavor, which is why I became curious as to what else could explain the difference in flavor.
