Cold crash?
« on: August 28, 2020, 01:32:44 AM »
Hey everyone, I'm a new brewer and I'm looking at an IPA recipe and it mentions to cold crash 7 days into fermentation. What temp is considered to be a cold crash. I have a temp controller on my fermentation chamber so I can achieve about any temp I need but I'm not quite clear on what the temp might be. Thanks for your help.

I normally go down to 34 F and hold it there for 2-3 days, I keep my keezer at 37 F.

Close to freezing is best. The low 40s works just fine, but will take longer. I

Avoid suck back as the temperature drop creates a vacuum.  You may have to add CO2 pressure on the drop.

Keep in mind that cold crashing is an optional step basically for accelerating beer clarity.  I don't do it in IPAs.

Thanks everybody. I really appreciate the information. I am just following the recipe for Veteran's Day IPA in the recipe list from this site and it has cold crash as the last step.

Especially dont cold crash on a recipe schedule.  Do it on the beer's schedule.

I do 33-35 for 3 days. 
Some day we'll look back on this and it will all seem funny

I keg at fermentation completion then cold crash at ~34*F under CO2 pressure until I need the beer. Sometimes that can be a few days, sometimes it’s longer.
