This fermentation fridge was originally designed and created with one purpose in mind; to ferment beer in at a controlled temperature.
But once we started brewing large batches of cold brew coffee to keg and serve on draft, we soon realized that this fridge provided a great place for us to cold brew in a controlled environment. Being able to control the temperature at which your coffee steeps allows you better manage the outcome and flavors, as well as give you a consistent brew each and every time.
Building a custom fridge to accommodate your cold brew coffee equipment is just one of many ways that you can control the brewing temperatures.

Excerpt from Introduction:
After years of homebrewing, we had dialed in a few recipes that we really liked. However, with each batch we brewed, there was always some variation in the final product. After doing a bit of research and speaking with other homebrewers, it became glaringly obvious that fermentation temperature played a much larger role in the outcome of the beer than we had given it credit for. And so the idea for our fermentation fridge was born.
We initially thought about just buying a standard refrigerator and gutting it like many homebrewers do, but that wouldn’t work for our particular homebrewery because we needed more space inside. We also considered using a large chest freezer with a thermostat installed, but that wouldn’t work either because we didn’t want a top-loading unit; we needed access to the front of the fermenters (our shop, Keg Outlet/kegoutlet.com, had recently partnered with Ss Brew Tech and their stackable stainless steel fermenters, so we wanted to make something that would accommodate a decent amount of these as well as other large fermenters and oak barrels for aging ales). So we came to the conclusion that the structure would need to be custom made.
We both loved the look of old antique freezers and ice boxes, so we began creating specs to build and design something that had that aesthetic. In this story we’ll show our step-by- step process of framing, building, insulating, and wiring this beast. You can follow the specifications of this project and build your own — or — you can use this as an inspiration to build something uniquely suited to the space and equipment in your homebrewery.
