Anyone looked into this much?
I've had a bottle or two before from WF out of curiosity.
I've always said the best foods on earth involve yeast or bacteria (with very few exceptions). The word 'ferment' is occasionally tossed around with tea production as a misnomer this is actually fermented with both yeast and bacteria.
Looking at the preparation it appears there's lots of ways to tweak this and possibly incorporate methods from other beverage hobbies.
So since the only non-alcoholic beverages in the fridge are lipton diet ice green tea and milk anyway I may try and play around with this.
