Im new here, just started making my home made Keifer every day. So far its OK but thinner and more tart/yeasty than the store bought that I have enjoyed. It occurs to me that , (unlike when i buy Kiefer where it tells you on the back what strains and how many billions of bacteria are present, ) I have no way of actually knowing which strains Im getting and how many in my home made. Can a person test it at home or is a lab expense necessary . Id like to know I'm maximizing its benefits because I have Crohns. Any thoughts?
