Re: water kefir??
My DH would eat our grains. He said they tasted like gummy bears. I believed him and tried it. Nope, didn't taste like gummy bears at all.
As far as the 'juice' I really liked it. We did it for a year or so, but decided to stop making it after we got way backed up on it and it was really just taking too much time!
My favorite was always with grape juice and when we sweetened with black strap molasses it was the best. (We didn't care for it nor did it kefir as much on succulent.)
