Im currently brewing my kolsch recipe. I noticed during the sparge that there was a gray film on the top of the grain bed. The grist is 10 lbs american pils. It was visible again at the onset of the boil sitting on top of the foam.
Ive been all grain for a while now, never have seen this. Any clues?
