Does sauerkraut go bad?

  • 4

If it's kept in a sealed container in the fridge, how long can I keep sauerkraut. I'm thinking that it's pickled, so for quite some time. Any thoughts?

  1. I once called Bubbies with that exact question about their sauerkraut. They said as long as the brine covers everything, it won't go bad. After awhile though, it lost its bright flavor and crisp texture, so I threw it out and bought a fresh bottle.

    1. re: Merryworld

      I bought the nice Mildessa white-wine sauerkraut from Germany - it comes in a tin so I empty it into a glass storage container. It doesn't rot, and I'm sure it doesn't get unsafe, but as Merryworld says, after a few weeks it loses its lovely delicate flavour. Could perhaps be used in soup, but if not, throw it out. Wish it came in smaller tins. I'll have to check if there are any sauerkraut/choucroute threads here. It is very nutritious and good with lots of things, like salmon or trout. I've also made a lovely tart - similar to a quiche or Alsatian tart - with well-drained mild sauerkraut.

    2. I've kept it for as long as five months -- the texture softens a little, and the flavour can get a little harsh, but it doesn't really seem to go bad.

      Sauerkraut is made by lactic fermentation, so the main thing to watch for is to keep it covered with brine, and to keep an eye on the color of it. If you see pink, pitch it. The gazigglies that make it pink can make ya pretty sick if you eat them, and they mean that it's been improperly fermenting somehow.

      1. I freeze mine. Tastes great -- not to worry -- and it keeps for months. Be sure to use a plastic container because it's expandable as opposed to say a glass container which is breakable.
