I bought a jar of capers packed in water, acedic acid and salt. My question is how long are these good for after opening? It doesn't say anything about refrigerating after opening either.
hmm, I have a jar that I keep in the cupboard. Wonder if it's any good? I figured since it's in vinegar it would last a long time, but then again things in vinegar can still spoil. Hard to tell since the jar is green. I dont use capers very often. I've had this jar for about a year.
I have had some i the frideg for at least a year, but they do basically last forever.
BUT, it's really important NOT to maintain the liquid. In other words, don't drain them, use some, and fill the jar up with water for the leftovers. You need to maintain the correct acidity level to deter bacteria. So either save the brine it's in or refill the jar with straight vinegar to be sure.
