Title: Cold crashing question
Post by: CJOCONNOR on November 02, 2014, 07:21:00 AM
Two questions about cold crashing -

1) I don't have a fridge that the primary fits in.  Is it a good idea to put the primary outside in +/- 40 degree temps for 12 hours or so?

2) I've never tried saving the yeast cake and dumping a new batch on it.  I want to try this time, would cold crashing affect the yeast's ability to ferment the next batch?

Any advise is appreciated, thanks!

Some with freezers do just that and set the thermostat to ~35 and crash it.  Others take it down gradually, ~5F per day, on the logic that dying, crashing yeast release off-flavors on the way down.   Death versus natural hibernation.  YMMV.

I  transfer the brew off of the yeast and in to kegs first. Then you have a clean brite beer to cold crash. The yeast does dissolve back into the beer if left in, going cloudy.
