As for storing the unpasteurized beer I offer this experience. I was a sub contractor on a new beer distributor building for the loading dock and doors. There was a Keg room that had two high speed doors and was kept at 32*. Only the truck inside loading area wasn't temp controlled. We had 4 high speed doors for the storage area but I can't remember the setting. It was chill enough to wear coats for servicing. I keep my kegs at 33*.
