Fermentation Support Forum

Can I ferment something that comes out of a can, already cooked, etc., like V8 juice? What I mean is, will the probiotic strains appear into it if I ferment it on the counter, just like a fresh veggie juice?

My guess is that you'll have to culture it with something if you want it colonized by desirable microorganisms. Maybe just putting a cabbage leaf in it would be enough.

I'm no microbiologist but it may ferment but it would be extremely difficult to tell which bacteria you have going on in there. Also if the v8 is pasteurized then there will be no bacteria present. As an "insurance policy" you can purchase a lactic acid bacteria/ vegetable starter culture and put it in there then it will ferment. As I said, if it's been pasteurized there will be no bacteria so you have to add the macrobiotic stains to your juice. I also second the cabbage leaf idea but from my understanding it has to be raw. Not using any culture or anything you could possibly increase the likelihood of bad/undesirable mold or bacteria.
