I tried an older Glen Mhor bottling from Gordon & MacPhail, and was quite unimpressed. I could see why the distillery closed!
However, regardless of the taste of the contents, it is true that bottlings from silent stills are fast appreciating in value.
But having said that, Glen Mhor isn't the most glamorous or sought after malt, so whilst I'm sure you'll find a buyer and make a few quid, I'd let my tastebuds appreciate its value!
Cheers,
