Made a kolsch about three weeks ago. Over the last week, I put it in a room at 50 degrees, as I dont have room to do a full crash cooling in a bucket. Racked to keg today and was planning on washing yeast or maybe just saving slurry and saw this on the top of the beer. I dont think its infected, didnt smell funny or taste wrong. I have never used this yeast before and want to hear some opinions regarding what these little floaters are? They dont really have much mass to them and I am thinking just remnants of the krausen that was.....Thoughts?
