I have seen people extend a mini fridge like mine with the use of insulation board. I contemplated getting something bigger but I am going to be moving in the next few months so I thought smaller is better for now. Why can't you use an upright freezer? Not enough room? I do a batch every other two weeks, have no AC in the house, but I do have a basement. I do 7-10 days in the fridge then bring it down to the basement. It is a good rotation schedule for now.
We will see how happy the beer is tonight when I get home. ( if she is bubbling away or not)
