I`m currently brewing a Stella Artois clone (Dave Line recipe). Its at secondary stage in the carboy at the mo. Today I had a quick look to see how its getting on and notice an oily looking film on the top. There`s also a some slightly strange looking floaty bits too. This is my first attempt with bottom fermentation so am unsure whats occurring. I used safe ale lager yeast(yellow sachet) sprinkled over wort at 20 o c then mixed in. All kit was thoroughly sanitized with vwp. I racked it into carboy and added finings at same time as to recipe but have read thats too early? I`ve got a wadworths old timer clone on too and all seems fine, did the same thing with finings in that too but new yeast crop is on top should I add a seconD lot of finings? Help please :hmm:.
