A dear friend sent me kefir grains (not to be confused with real food grains!) and I decided to make kefir water, since I can't have dairy. This was my concoction!
It's basically filtered water, kefir grains, organic sugar(the grains will eat them I was told), an apricot. Yep that's an apricot, the bloated orange thing inside. You will also need a clean glass jar with a lid, the size would depend on how much kefir water you're making.
Every couple of days you need to rinse the kefir with filtered water. You'll need a strainer, preferably a plastic one. You don't want the kefir grains to touch metal. Then you put the filtered water and the kefir in the glass jar, add fruit if you like, then the organic sugar. I was told you can use molasses too.
Oh and yes you are supposed to drink this stuff! ;). I normally wait at least 3 days before I drink some.
