Hello ladies and gents. I thought I was going to be ready for bottling this thursday, but I can still see very small clumps or grains of yeast buoying around the top of my beer. They seem to move up and down a little. I'm obviously new to this and am wondering if I need to filter this stuff out before bottling, or does it go in the beer? I've read some mentioning of "yeast falling out" and that seems to make perfect sense here, if I'm not misreading. If that's what I'm waiting on, how long does it take?
