I saved some of the yeast cake from my chubby cherrub pale ale (Bry-97) and just noticed there is lumpy stuff on top. I have done this a few times before but usually just settles out nice and flat, is this something i should be worried about? I had a quick sniff and it smelt alright to me but I am still unsure can anyone put my mind at ease
