Rejuvelac Soda

[Nerium]

I would really love to experiment with using rejuvelac as a starter for soda. I've made and used a ginger bug for sodas, but I'm making rejuvelac anyways for nut cheeses and wondered if it could double as a soda starter. I'm thinking of a basic ginger/lemon soda to start, but I'm open to flavours of all sorts. I'm also wondering what would happen if I added rejuvelac to fresh pressed fruit juice. I'm trying to figure out amounts and ratios and I am afraid to just experiment, because I'm not a huge fan of wasting ingredients (and time) if someone else may have the answer. Any advice would be great. Thanks!
