I have a question for our "pepper afficianado"!

I put up several pints of "Pepper Sauce" - just an assortment of tiny hot
peppers packed in jars and filled with boiling hot cider vinegar, then
BWB'd for 15 minutes. This was about 3 years ago, and I still haven't
opened but one jar. I'm the only one who uses it, and just the vinegar
sprinkled on greens or black-eyed peas, with an occasional chopped pepper.

Question is, can these go bad? I'm nearing the end of the 1st jar, and the
taste is still great, maybe better, but the liquid has become very slightly
cloudy.

Thanks for your expertise...
