reviving unfed grains

[Guest guest]

Someone has given me kefir grains that were stored in a fridge in a ziploc

without milk for about 3 weeks. I've fed them every 24 hours for 5 days. They

seem to be trying to work. I'm not sure. The kefir is slightly yeasty and has no

nice tang. Maybe I'm too hopeful, maybe they aren't fermenting the milk but the

milk is merely doing what unchilled milk does. Do you think that they could be

alive, or would milk turn thick in 24 hours at room temp without kefir grains?

Thanks,
