So, this is a weird one for Phoenix, AZ. We've been experiencing freezing temps here in the Valley recently. I use a fermentation refrigerator that I keep in my garage. I keep my johnson control between 66 and 68 for most of my beers. With the cold snap recently, I cant keep the temp that high. Its been holding inside the fridge around 58. I have a cider in there now that needs to be in the high 60's and I'm brewing an ipa tomorrow that needs to be in the same zone. Does anyone have suggestions on how to increase the temp a little inside the refrigerator. Should I wrap my carboy in some towels or a blanket? Any advice would be appreciated.
