I just recently was able to get an old fridge and I am turning it into a kegerator but in the meantime, I have an IPA that I would like to cold crash.

Does Cold Crashing really make a difference? If so, for how long at what temp? I tried searching on HB but couldn't find an answer.

Thanks for the help!

Of course it makes a difference, and is particularly useful when dry hopping with pellets.

I usually do three to four days at 34F, but have gone longer on occasion. As I do all my fermentation in glass I can observe how the beer is clearing and let it run longer if desired ...

Cheers!

Thanks for the help. Since this is my first time doing it, anything wrong with only going it for 2 days? It seems like it took the beer almost 24 hours to go from 60-40 degrees.

I recently crashed at this temp and it made transferring to a keg much easier! Seemed to not only clear the beer but also keep the particles down while using the racking cane!

Sounds great! I thought it would help when racking it. Anyone ever racked thru the bev out tube?

I've had good results with 2 days.

As I understand it, the cold temp forces the yeast and other particles out of solution and they fall to the bottom. Extra bonus if you keg, the beer is down to a better temp to accept the CO2. I've also noticed clearing of the beer while it sits in the keg. All my stuff gets crashed now. Sometimes for a day, sometimes 2 or 3, depends on how much free time I have to deal with it.

What are you hoping to accomplish; I.e. what exactly are you asking? If you're asking "will this make my beer taste better" then the answer is not really. Cold crashing is just a method to encourage the yeast to drop out. And yes it does take a few days. Cold crash a starter flask sometime (I.e.. Stick it in your fridge) and watch it change over a few days.
