I've been making kefir for months now and never had any problems. i normally "rest" my kefir grains in the fridge for a couple of days out of the week, when I get too much, and they always seem to bounce right back. I put them in a glass jar with some milk til I"m ready to make more.
They don't seem to be doing their job anymore, the kefir is really watery and doesn't smell yeasty like it usually does. The only thing i can think of that I did differently is that I put them in the jar with a little milk and left it on the counter for a couple of days, instead of refrigerating it. Could this have 'killed' them? I haven't rinsed them or anything. Is there a way to revive them? Or to tell if they are really dead?
Thanks for your advice!
