Can water kefir grains be turned into milk kefir grains and if so how?
It might be technically possible (with a lot of work) to get water-kefir &quot;grains&quot; (or, more correctly, SCOBY, a Symbiotic Culture Of Bacteria and Yeast) to survive on milk, although I'm not sure what kind of drink that would produce.
But if your question is, as I suspect, whether you can turn the water-kefir SCOBY into what people commonly refer to as &quot;milk kefir&quot;, then the answer is an absolute no because they are completely different cultures.
This is a common point of confusion, and it arises from the fact that &quot;water kefir&quot; is a misnomer. The word kefir properly refers to the culture and related drink based on milk, and it probably originates from the Caucasus area.
On the other hand, what we informally call water kefir is actually a completely different culture and drink, more correctly called tibicos, and it probably originates from the Americas.
