Yeah, I tasted and went ahead and bottled already. It tasted great! So, we'll see if something strange turns up in my bottles here in a couple of weeks. I wonder if it has anything to do with my fermentors being on a cold concrete basement floor. Yeast floating to the top where it's warmer?? I'm reaching here, just don't know. It really looked like the trub that I usually see on the bottom, just floating on top.
