Homebrewers and potential homebrewers, do you live in an apartment, small house or other constrained space, like I do? Do you want to take your fermentation temperature control to another level but but don’t have room for a dedicated refrigerator or freezer? Are you OK with ales but need better cooling for lagers? If any, or all, of those things are true for you then please consider backing the BrewJacket Immersion Pro on Kickstarter.

I am a budding home brewer with some serious space constraints among other things. We live in a small house and already have two temperature-controlled refrigerators for cellaring beers and have no more room for a fermentation fridge. And seeing as we need more cellaring space neither of those will be converted to brewing use. But I do have a spare small shower in a second bathroom that would be perfect. Most of the winter it has been sitting at 60° F but it will warm up come warmer weather. I clearly need better temperature control to undertake brewing.
The BrewJacket Immersion unit has been around for a couple of years now but was so far restricted to cooling only. Their new, upgraded version which will both cool and heat to 35° F from ambient temp is currently being funded on Kickstarter. There are still 9 days left and they are just under $11,000 away from the $65,000 goal.
I backed the project at the No Wait Carboy level in which, if funded, I will be sent a current BrewJacket Immersion cooling-only unit in April and then be sent an upgrade [new circuit board] in September that will allow both heating and cooling.
How it works: It consists of a “highly insulated, waterproof, beer-proof, heavy duty jacket” and the rod which goes into your fermenter with the solid-state cooling (and heating) system connected to that.
Now this unit isn’t exactly cheap but it does solve serious space issues for many of us, along with replacing that fridge or freezer and dual-stage temperature control and heat source which would be needed otherwise. They are compatible with over 20 different fermenters, with more coming, and work with 5-gal batch sizes.
Here are a couple reviews of the cooling-only unit:

- HomeBrewTalk
- C|NET
- A comparison review of several options, including the Immersion at Homebrew Academy
If this might solve some of your homebrewing issues then please consider backing the Immersion Pro on Kickstarter. I truly need this device if I hope to start homebrewing this year. Thanks.
