If you go the small refrigerator route, try to avoid ones with freezers in them. That eats up space. Also be prepared to rip the plastic shelving off the door if it’s there as it also takes up space. I’m very limited with space so for my first fridge I ended up with a Magic Chef Beverage Cooler. It has a digital temp controller (fairly accurate), no freezer, and a glass door. And it fit under my workbench with about 1/2" to spare
Worked great as a beer fridge and and for fermenting lagers.


However it couldn’t get down below 41 degrees so my ability to truely lager was limited. When I moved to kegging I picked up a Sanyo fridge that could get down into the 20’s. I added a Johnson A419 controller and it can lock it at 31 degrees and holds it perfectly. It can hold two kegs and a 5lb CO2 container.

Ideally, I’d like to convert a chest freezer but I simply don’t have the room. But I’m happy with the way things are set up now.
