When I buy black olives from the supermarket olive bar how long can I keep them in my refrigerator? How do I know if they go bad?

  1. As long as they are still covered in the brine they should last indefinitely. If there is no brine or juice, they might get dried out.

      Thanks, I never get the brine. I'll start doing that when I buy the olives.

        There was a good eats episode about keeping olives. I think he said that if your brine runs low or if you don't get any with your olives, you can just make your own or just use olive oil, i think. You might want to search for the show to see exactly what he recommends.

          Great, thanks!

    2. You'll know when they start to go bad. They gut mushy and mold. As ESNY said, the ones in brine last longer.

        The whole history of salt fermentation is a fascinating bit of food history. In addition to olives there is also sauerkraut, kimchee and all pickles.
