I currently have a 15 cu/ft freezer with a temp controller (blue digital…can’t think of model offhand) that is keeping my kegs and assorted bottles at 32F. As the cold weather comes in the next few weeks what options do I have to make sure that sub zero temps don’t freeze my beer? Will a dual stage controller work with the freezer on one and a light bulb on the other? Will condensation F up a light bulb? Any info would be appreciated!
