Come on get it right - Whisky=Scotch, Whiskey=Irish.I am half-Scots but in spite of my best efforts I can't develop a taste for the stuff. I can handle pretty much any other spirit (although I don't like anisette drinks much) but Scotch whiskey regardless of type just doesn't do it for me.
TBH I've had one with Lillet, and made them at home with Noilly Prat but both of those are French which is (I think) the point. Not used an Italian or other vermouth. I also use a full rather than a half measure as I prefer the taste (it's undiluted spirits so dry enough anyway) but experiment to taste.
Just don a tux, enjoy several and then post the resulting pics.
