Bought two bottles of kombucha at the grocery store, having no idea as to what it is. Did a little internet research, and I find it's some sort of "health drink." I have so far consumed one bottle; it tastes a bit like fizzery apple cider. It has a thin layer of sediment on the bottom of the bottle, like you'd find in a homebrewed beer. Is the drinker of this elixir supposed to consume the layer of sediment? Inquiring minds want to know...
