Today before I read this post, I was searching kefir on the internet, and I found a network of people that share authentic kefir grains. I am trying to contact a person that is about an hour away.I will try the lifeway kefir brand, just in case. I am kind of paranoid about the commercial brands though, becuase they all have sugar, and I think sugar is a big part of my stinky problem. Thanks for the advice.
