Where are you located? I have a source that sells unpasterurized raw milk and he gives away extra kefir grains. He has a gym/health store and you can order the milk to grow kefir in too.
I'd be willing to give you a small amount, been growing them for about a year now.
When my jar get too full, I break a piece off and swallow it like taking a tablet.
My contact info in on my profile page.
I have a small amount that I grow just for myself, but I have shared them recently with two hounds who contacted me. My kefir grains are too low to share right now. But if you
contact me in a month or so, I may have a few grains to share.
I got mine from a guy who owns a gym in Woburn, who may have some to share. I sent you an email with his contact info.
