    Yesterday I tried a process change brewing an Oktoberfest. I have a HERMS setup with a plate chiller. I tried pre-chilling the garden hose water through the HERMS coil, which was in an ice bath. On a warm day, I got wart temp down to 57 deg F, wanted 50 deg F. I then put the carboy into the frig and gave up waiting for 50, pitching at 53 a few hours later. Do any of you guys leave a carboy in your frig for an extended period before pitching? I have to think contaminate risk is low even without the competitive environment created by the introduction of the yeast. Thoughts?

    Though I've never done this, as long as your sanitation procedures are thorough, you should be just fine.

    While I am sure you will be just fine, I know I have done it many, many times in the heat of summer. I would pitch the yeast and cool. It's really a double edged sword, because the yeast may throw a little funk if there is a big swing, but not pitching the yeast will exhaust your wort antioxidants, which may lead to a lack of malt presence,hop presence and accelerated staling of the beer. The reason being is that as this cools it will suck in Oxygen, and while I know you need oxygen for fermentation, its for the yeast. The yeast can consume a crazy rate of oxygen, at a fast rate, thereby not exhausting those malt antioxidants. When wort is exposed to oxygen not in the presence of yeast it will exhaust its reserves first, which can lead to the above and even a possibility to darken the wort (think sliced apple). Of course the sanitation aspect aside.
