I have an IPA in the fermenter that I will be kegging at the end of the week. I have not cold crashed in the past but like the idea of having a much clearer beer. I understand just putting my fermenter in the fridge will suck in air and risk oxygen getting in which we all know is bad. I have also read about cold crashing in the keg. So what is the process there? Do I just transfer to keg, purge with CO2, and put in the fridge without pressurizing the keg for a day or 2?
