I recently brewed a belgian quad and decided that I would cold condition it for two months after a month of primary. I have it sitting around 45-50 degrees. Obviously with the drop in temperature, a vacuum has formed and the solution in my airlock (Star San) has been sucked down into the beer. Not concerned about that since my batch is 5.5 gallons. I have a little solution left inside but the airlock cap that floats is all the way down. My concern is that air is getting in.
I thought that perhaps the pressure had stabilized, so I topped the solution off with water and sure enough it got sucked back in to the same low level. I assume that I shouldn't add more water to the lock since it seems like the pressure isn't stabilized.
Should I be concerned with air getting in? If it is, can I do something about it? For future batches that I cold condition, is there something that I can do before hand to not run into this problem?
