I just opened a new bottle of my favorite (a'bunadh), but was
surprised that the mildew/must note was absent. By all accounts, it's
still my fav', but I was a bit saddened at the loss of this
characteristic. Has anyone else noticed this trend, or does any of you
have any insight as to why? This bottle was from batch No 16.,
probably purchased but not opened 2 or 3 years ago.

Thanks, John
