I'm surprised that in all this talk of flavored martinis, no one has mentioned the advent of designer (spelled
expensive) bitters.
Back in my drinkin' days, (thankfully years in the past); the Friday night martini used the tiniest dash of bitters from a bottle with a yellow label. It's pretty much all I knew. Now?
An explosion of flavor! (These are local to me. I'm sure there's millions of others out there)
