Cold Crashing
« on: April 25, 2015, 02:26:39 AM »
I'm guessing there isn't a consensus here, but how cold do you do it and for how long? I have a chest freezer and a temp. controller FWIW.

justin- depends. if you're cold crashing before bottling to improve clarity...give it a week.  i cold crash before fining and do it for 4+ days...schedule depending. then i add my gelatin and keg. cold crashing and conditioning is beneficial to your beer, so as long as you can and are willing to go....your call.

+1 to the above. I crash a couple days ~ 32F. And on beers I plan to fine, the beer needs to be cold first to use gelatin or Biofine anyway.

I go from the fermenter straight to a keg, into the kegerator to carb and cold crash at the same time.

Should I be measuring ambient for this or actual temp?

Doesn't matter.  The beer will equalize in less than 2 days.  I take the probe out of the styrofoam and go ambient so my freezer doesn't burn out.

Ok. Just thought the beer may freeze at some point. Alternatively I was concerned w my chest freezer running for so long if it's measuring the beer.

Measure ambient. If you measure the beer, the freezer will run for hours before it hits temp.

You have to go quite a bit below 32 to get beer to freeze.

If you're cold crashing, the fermentation is done and you don't need an airlock.  I just seal the fermenter before crashing.
