I am a new brewer and I’m working on my third extract batch. The first two went off without a hitch and taste great. I’m in the middle of primary fermentation of a Kolsch extract kit. About day five, I started getting a “yeasty” looking haze on the carboy glass (the haze in the beer looks the same as the other batches). The haze goes from the bottom to about 3/4 of the way up. The top quarter looks clear and normal.
The initial specific gravity was 1.050. The carboy in a dark place in my basement holding temperature between 62-64 deg F. Everything else looks normal with activity staring about 24 hours in. and nice Krausen by day 2 with lots of activity. After day 7, the krausen is collapsing and activity slowing.
My question is, Is this normal? Something to check out? Or do I just need to really clean it ( I thought I had) when I transfer it to the secondary fermentation carboy.
Thank you in advance for any advice.
