You know, bitters didnt used to be a "once in a while" thing. It was practically required in any GOOD drink at one time.
how they fell out of favor is beyond me. There used to be tons of different types, now you would be hardpressed to find a liquor store that even knows what they are.
I wonder how long a bottle of bitters lasts? I bought one years ago for my father-in-law's manhattan's some years back, and just keep on using it for myself. I'll forget I have the bottle for months on end, but definitely like the extra dimension of flavor.
