I have recently installed a beer engine at my bar. I seem to have a unique problem. I’m very short on space so I have to keep the casks in my walk-in cooler which is 40f. Is there anyway to keep the casks warm? An electric blanket? Some kind of heating coil? I have a lot of money invested in this system and I want to do it right. I’ve read too much about bad cellarmanship and I don’t want to be that guy. Has anyone else had to deal with this issue?
