Can Sauerkraut Go Bad

No view

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..
