kefir - water vs coconut vs milk

[Guest guest]

I am experimenting with kefir. I'm making it with all kinds of things, and would

like to see if anyone could help me with a few questions.

Is there any research on what probiotics, enzymes and bacteria are found in

different types of kefirs?

Is it best to make kefir with a fat - like coconut milk vs coconut water?

Does it destroy the probiotics, enzymes and bacteria to freeze the kefir - I'm

also making kefir ice creams.

Thanks,

Karin
