First Batch:I let the first batch sit for 3 days, strained it, and set another batch going.
This first batch was palatable, but not particularly something I would eagerly reach for as a refreshing beverage on its own.
I poured half in one pitcher and half in another.
In one pitcher, I added about half a cup of freshly squeezed lemon juice to about a quart of Water Kefir. Again, palatable, but not the awesome beverage I had hoped for.
In the other pitcher, I added about 1 tsp vanilla extract to the generous pint of Water Kefir and let this mixture sit on the counter for a day or two to increase the fizzy bubbles. This batch I found more favorable and I think I might be able to get the kids to at least try it, particularly if I can find some bottles to bottle it up in and hold more of the bubbles in so it's more like soda. (because I'm sneaky like that)
