My first batch of Kefir, as I suspected, was way too yeasty/zingy. So I threw the first batch out. I split the grains up between two pint jars for the second batch and it worked perfectly. It was weird though, because it only took about 14 hours to be ready vs. the 24 hours it took the first time around with twice as many grains in a one pint jar. I'm a little confused about how that could have happened.
That's my Kefir update for now.
