I did research and I did read Doms site. If you had read my second post you would have seen that I did do research and I did find out what it was. I also checked out videos on Youtube of folks making "Water Kefir"
Something that peaked my interest in Dom's site was making water Kefir with the addition of ginger making a sort of Ginger Beer. Sounds delish to me. I might hafta order me up some grains and play around with making my own.
