Anyone who drinks Scotch Whiskey in a cocktail is a lout or a dandy and should be shunned.
There really is something to adding a bit of water though.
I always add water...more than most.
I’ve likely burned out my throat and need to thin the Whisky a bit so it’s not so painful.
Now, **IRISH** whiskey in coffee is another story entirely. . . . (grin)
My ex-father-in-law once grabbed my bottle of McCallans and poured it into a glass of Country Time lemonade. The divorce happened shortly thereafter.
Actually, a Scotch Sour is pretty good if all you have is cheap Scotch.
