Before



After



Not really worried about it Just curious This is my first all grain Wheat beer as well as the first time using my well water that has been filter for my beer so yeah

recipe is 7lbs Wheat 4lbs Pale 2row .75 tettanager .25 Sazz 5gal

the pics are kind of small so its hard to tell. but if your seeing what i think you are i had the same thing happen with an AG batch i got from a group brew at a local brewery. i thought it was just yeast floating at the top of the fermenter. what was funny is after a while it fell and there was the usual light brown yeast stuck to the inside of the carboy at the top of the water line in a nice wide ring. i just jostled the carboy and it fell to the bottom.

Looks like krausen. Leave it alone.
