I've had a min-max indoor-outdoor thermometer on my aging chest for a month or so. I was seeing minimums in the chest below freezing. Which is flat out impossible and I was thinking I would need to replace the thermometer. So, yesterday I'm in the chest doing some QA sampling when the 2005 barleywine cuts loose and the temperature drops to -3F!
The sensor was sitting on top of THAT keg right next to the relief valve.
