Beer Cellar Question to Pub Landlords out there---?

I'm not an expert, but I've talked to enough to have a suggestion on this one. I even talked to a local brewer a few days ago about it. He brews lagers exclusively and keeps then in a refrigerator before handing them over to his distributor. You don't want to turn it completely off, just raise the temperature a bit to bring it up to 12. This will help you save on energy coast while not risking quality of the beer stored in it.
