Okay, Northwest Pale Ale, 3 weeks in LBK, followed directions on can. Followed standard sanitizing procedures, but I did have a couple homebrews that eve, so my attention to detail might have been slightly compromised. Nothing major that I can remember. So I think that this batch has: A. been Infected. B. floating yeast rafts. C. been agitated while moving around, knocking off some of the dry krausen ring which is now floating on top. Tastes like flat beer. Nothing nasty. The alcohol taste seems up from what I am used to, but this is the highest ABV batch I have brewed. I decided to cold crash. There is no filmy substance, just these floaties. Any thoughts.
