I don't know. The bubbles have pretty much collapsed and look like whitish mold, and now there are floating white things on the brine. And the brine isn't clear any more. The smell is good but still not very sour/tangy, so I still have hope.
Some friends who know more about this sauerkraut business than I do are going to get me some more info. Right now I have no desire to taste it - I need a little more encouragement I think!
