Warming a firkin


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?


  1. This is different, not sure if you are "taking the Michael" but here goes. Cask ale needs to be at around 55 degrees Fahrenheit to start working on its secondary fermentation in other words clearing down. If you are at 50 degrees this process becomes very slow. If the ale is at extra cold lager temp I can’t see that happening at all.

    No matter what you use, you will wasting electric; by warming the cask you will have one system working against another. A better solution would be to try to run a 3/8 pipe to another room and store it there or put the Cask Ale somewhere around the bar in a cooling jacket. There are ways and means but I think you are on the wrong track. 😮

  2. Thanks for the response hoppy but let’s say for arguments sake that I have no other options. What about the coil blankets that would circulate water from my water heater?

    How long will the cask I have stay good if it is stored to cold while I figure this out? Once I get it in the correct temp will it be ok? It is a 10% abv imperial pumpkin ale.

    Any other suggestions would be much appreciated!
