Crash Cooling and Bottling

Nagel Family Brewing:
Does anyone crash cool there beer in the fermentor and then bottle condition.  Can it be done?  Is there still plenty of healthy yeast in solution that would carb the beer in a reasonable time bottle conditioning?  Is there any negative flavor impact potential for the temp swing before bottling via priming sugar?

hopshead:
Yes, there is plenty of yeast.  Before I sold my house and moved to an apartment, I fermented in a chest freezer w/ temp. controller, and I crashed cooled all my ales down to 34-35 for a couple of days then bottled (primed).  Perfect carbonation and clearer beer too.

jackfromjax:
If you crash cool, be sure to disconnect your blow off tube assembly (if your using one).

I made that mistake and turned the temp control to my fridge from 68 to 32.  The next day I went out to check the progress and noticed that most of the carboy neck above the beer was filled with sanitizer that had been sucked back into the fermenter.  Luckily there was such a sharp division between sanitizer and beer and I was able to rack out most of the beer.  Lessoned learned.

guvna:
It may likely take longer to carbonate, but with patience it will work just fine.

  Use a "S" type air lock when crash cooling. They work in both directions.
