Please help. Saw this floating at the top of my beer. I noticed dirt looking specs on the inside of the glass above the beer. A week later I have these white spots floating on top. They aren't furry... so I don't think it is mold. The carboy wash rinsed and sanitized with starsan before I transferred. I used a White Labs English Ale yeast. Should I drink it anyways or would that be certain death? I am mostly just concerned about contaminating my keg. Any thoughts?
