Brewed this today, and even right after transferring to carboy and shaking the heck out of it, it looks like this. I'm not really that worried, because I've had wort look like this before, and the beer turned out fine, but I'm worried this messes with me hydrometer readings. Doing BIAB, I generally get about 84% efficiency, but today, based on my reading, it seems I got 91%
Secondly, it seems I could get my numbers back down to where I'd like them if I add a half gallon of water. My carboy holds 6.5 gallons, and there are only 5 in there now; could I potentially open it and carefully add another half gallon of water, even though I've already added the yeast?
