Sauerkraut

How long will an opened jar of fresh sauerkraut last? I bought a jar that was in the deli section at the grocery store to make Reuben sandwiches and now have 3/4 of the jar left.

  1. A couple of months.

      Thank you. Guess I'd better throw it out.

        Why not eat it?

    2. How long did you open it? Did you refrigerate it after opening it?
      Kraut will last a very long time in the fridge after it has been opened. Usually you can tell when it's gone bad cuz it changes colors in a VERY distinct way!

        It's been refrigerated. Looks exactly like it did when I bought it but the date says best if used by 11/13. The only way we really like sauerkraut is in a Reuben sandwich.

      2. I'm not sure if there is any real agreement about this, but I think unless your sauerkraut has ingredients other than cabbage, salt/vinegar and water, it should last indefinitely. Sauerkraut is fermented cabbage, and the organisms that cause the fermentation also keep it from spoiling. (In fact, sauerkraut is a suggested food, along with yogurt and acidophilus, for keeping your digestive tract healthy.)

        I buy fresh sauerkraut at one of the greenmarkets here in Brooklyn (Dr. Pickle), and I asked them about storage, They said that fresh sauerkraut should keep indefinitely in the fridge. I've used sauerkraut that I've had for weeks (maybe 6, maybe 8 weeks, even longer) with no problem.

        Suggestion for you: cook a couple of hot dogs in one pot (you can simmer them in water to cover), and for accompaniment take some of that sauerkraut and add a little water and a tablespoon or so (doesn't have to be exact) of plain vinegar and bring it to a simmer. Slather some of your favorite mustard on the hot dogs and eat them along with the sauerkraut. It's comfort food (at least for me), and you'll be doing your digestive tract a solid favor.

        If you're not comfortable with the kraut, you can always toss it and buy some more, but you really don't need to.

        Good luck in any event...

        1. If it looks OK, it is OK. Sauerkraut was made to keep well in a crock all winter.
