I've been brewing kombucha for a couple of months now and I've noticed that the brew seems to be getting cloudy. I brew 1 gal. in a 1 1/2 gal., glass jar. When I'm ready to make a new batch, I pour all, but about 2 - 3 cups into a container to store. What I pour in the the clean container is clear, but what remains in the jar is quite cloudy. It this a problem?
