Only my second brew, but I am brewing a Hefe currently. OG was good when tested for 4 straight days. When I went to bottle today (spent 3 weeks in primary---no secondary), there was not any sludge on the top of the brew, but there was some sludge residue on the side of the bucket. Upon transferring to my bottling bucket, there was about 1/2 of thick, white sludge at the bottom. Do I have anything to worry about or am I overreacting? Thanks!
