@ossobuco,
Virtually all of my trying of these scotches was because my husband and I had a friend who was a connoisseur's connoisseur and liked to have several good scotches, bourbons, and a few other things like cognacs and marc.. to have for his guests. Oddly for this fascination, he wasn't an alcoholic. More of a foodaholic. We used to have a scotch or bourbon while watching Washington Week in Review before going out for Chinese food..
So, over about two decades, 1976 - 94, I've tried..
(and no, I can't elaborate on the differences)
I cut off the years on the list - old single malts were near priceless back then and astronomical now.

I had something with a long name that I don't now remember when visiting Piffka and her husband.. I don't think it was on the list, and it was tasty.
