So cool! Never heard of it and all I do is research! Is there supposed to be an unnoticeable difference from regular cheese culture? Is that what a lot of the vegan brands do?Rejuvelac is made from letting grains or seeds ferment in water, and is used in many vegan cheeses as a culture. I've always been afraid of fermenting anything myself, but I've read so much about it I feel I should at least try!
