Can Apple Cider Vinegar or any vinegar, go bad with time so you can't use it as food?

Yes. Some bacteria and yeasts can live in acetic acid up to 9% and use the acetic acid as a carbon source.

Anecdotally, I've had Trader Joe's orange muscat champagne vinegar go bad on me. I didn't notice the recommendation to refrigerate after opening, and after a month or two open at room temperature it turned a darker color and started smelling funky. I'm not sure if it was actually inedible, but it certainly got manky enough that I didn't want to try it out.

It kind of goes "rancid" after a long time, you'll know if it happens it's unmissable. It would almost certainly not be harmful to you, but then, neither is sour milk and I sure don't want to be drinking much of that.

I had a half bottle of balsamic vinegar gel up on me once. Still have no idea what happened there.

KathrynT, maybe it was the mother? It's a big jelly blob that keeps growing and will consume all the vinegar if you let her. I've never seen it in balsamic though.
