Primary for 10 days and its been in the secondary for 20 days. I just finished putting my kegerator together. If I put secondary in the kegerator to cold crash, how long can I leave it in their. I ask because I was going to put it in tomorrow and might not be able to keg it till later in the week. Should I wait to put it in the kegerator until a day or two before I know I'm kegging?
