Re: Here's what I bought

For one commercial kefir is fermented from a starter culture.Meaning that some milk is fermented in grains then removed and more milk is added to the milk that was removed.The end product is milk fermented from kefir milk not from kefir grains.Its not just the bacteria but the polysachrides(spelling)and other benefits that the grains give the mixture.The grains are very complex and much is unknown about them.Its like saying that bottled milk is just as good as mothers breast milk.
