I also ferment kefir water! I do water kefir, milk kefir, tepache, kombucha, ginger beer, and occasionally sauerkraut. I even have a little "fermenting" shelf in my kitchen where they all live. My kids love water kefir when we mix in peach juice. I usually let it ferment way too long and it tastes a lot like apple cider vinegar - that and my kombucha. I typically add both of them to my afternoon ice tea and sometimes I make a super sour face when I'm drinking it. Ha! I need to be better at making and drinking it quickly instead of letting it ferment for so long. I hadn't heard of adding molasses to it, but I typically add raspadura which is unrefined sugar from the cane with molasses still in it. That or "brown" sugar they sell here in Panama, so maybe I don't need the molasses. Mine is always a caramel color. Great post! I love reading how others ferment drinks!
