When you cold crash how do you prevent liquid from the air lock from being sucked back int to the carboy? Are you worried about introducing O2 int the head space when the air condenses as it cools?
Obviously people do this all the time with out an issue i was just curious tho since there is enough space in my keezer to try cold crashing on this batch.
