What microbes are in kefir?

Answer 1

The list is long. Some people say only fifty - others say over a hundred species are there. The peculiar thing is that the microbes collect into little colonies that look like little white balls about the size of a grain of rice. These "grains" are essential - you can't just put all the species together in milk and hope for the best.

Answer 2

Kefir is a mixture of active yeasts and bacteria that aid in digestion. The kefir culture is so unique, it cannot be created in a lab, it must be collected from an existing culture.
