I recently tapped a new pale ale, and was surprised by the low carbonation. I normally always have good carbonation on my beers. I'm wondering if the cold weather is the culprit. My serving fridge is more or less outside, in an uninsulated garage. I know temperature affects atmospheric pressure, but is this the case?
Here's my normal carbonation schedule. Keg beer @ 30 psi for 48 hours. Turn to 12 psi for another 5 days. Seven days total. Then I usually turn to 5 psi for serving. Kinda the set and forget method. When the temperature drops, is this affecting the pressure at all?? I assumed that the regulator would be accurate at any temp. If there were changes in temperature, that's what the regulator is for, to keep the pressure where you have it dialed in.
If I'm not correct in my assumption, maybe I have a leak. Any thoughts?
