I'm definitely keeping an ear out for any 'classes' of this sort. Only having tried Glenlivet 12 and Nadurra, I've not got much fondness for Glenlivet but am always interested in giving them another try.
I meant to try Nadurra again a couple weeks ago at a tasting, but simply had too much variety there to try them all.
Were the Glenlivet glasses the big 'wobble but won't fall down' variety? I've got a couple of those and absolutely love them. Take some pics and share if you get the chance.
