I have tasted most of the F&F's - including Teaninich. I think all the ones I have tasted, except Mortlach, Bladnoch and Rosebank are below standard of what one could expect. We visited 5 UDV/J&B distilleries at this years Spirit of Speyside Festival - Strathmill, Auchroisk, Glen Elgin, Glenlossie and Mannochmore. It was ok to visit these "factories", but the whisky served was plain dull and uninteresting. In fact, I think they could have swapped them all without anyone noticing.
Apparently, these F&F's are quite interesting for collectors. I guess the packaging is more interesting than the content.
