Speaking of, I think mine has stopped reproducing. Someone told me they go through phases of growth and kinda pauses. Is there a way for me to check which mine is doing? I used fresh fruit in one of the brews and although it tasted great, it didn't taste as "brewy". Is that a quirk of water kefir?
As for not reproducing, I'm not really sure. I've had trouble with that as well. Someone suggested it was the agave, but they used reproduce even with the agave. Here are the variables I suspect for mine.
* gave away too many grains, so I didn't have enough to keep them happy, and feeling secure as a colony (I recently heard about biofilms, and kefir is one, and how they have to reach a critical mass of sorts in order to be, so I'm sure they need a certain amount to be happy)
* didn't change the water often enough over this past winter
* wasn't using enough agave per batch, so they weren't getting enough food
That's my theory anyway. We'll see how it's born out with my new batch of grains that a friend gave me (this is my third batch - number 2 is still brewing, but not growing).
