The BrewJacket Immersion Pro Fermentation Temperature Control System

I brewed a 4 gallon batch of ale. It's holding at 68° Fahrenheit. It works fine so far.

Got this because it was a) on sale and b) we “empty nested” to a smaller home. Previously, I had a chest freezer with separate temp controller for lagering. It didn’t make the cut to the new place. However, SWMBO agreed to this provided it “wouldn’t take up any more space than my hobby already did.” space saving; 5 stars. Fits in my 6 gal brew pail with the special lid, which was cheaper than buying a drill bit to do it myself. Brew Jacket: 5 stars. Works great as designed, just wish the drawstring top would close more. I think the gap I left may have something to do with the temperature drop slowness, but I’ll need to test again. time to work; 4 stars. I dropped the temp from 72F to 60 F but it took a few days to do. I’d hoped it would be overnight. See above comment about jacket and I may bump this up after retesting. Brew rod: 3 stars. I use StarSan religiously for beer making, and you can’t StarSan this immersion rod. They sell disposable bags you can wrap your rod in to protect it, but those are 1 time use. Replacement parts: 2 stars. I went to the BrewJacket website to see what they charge for replacement lids and rod bags, and it looks like they’re shutting this product down. I’m hoping it lasts for years, but if / when it breaks, you don’t have repair options. Overall review: 4 stars. Would buy again at the “under 200” price and strongly recommend it to people in apartments or condos.

I haven’t been able to use it yet. I have been a homebrewer for over 20 years. I look forward to using the new cooling system in January.

Received unit about 20 days after ordering...put together, plugged in - made sure it worked. Seemed OK. Started a new brew 2 days later, put wort into fermenter, plugged in the Brewjacket, set the temperature and went to bed. Next morning I checked to see if I could pitch the yeast (needed the Brewjacket to cool my wort about 5 - 6 degrees Fahrenheit). I noticed the device wasn't lit up. Checked the plugs, connections etcetera - no power on LED illumination - unit was dead. Used another thermometer to check my wort temperature - it was still exactly the same temperature as night before. Sent an e-mail to Brewjacket support. They responded later the same day and said they would send out a replacement power adapter immediately via 2-day mail. Had to put my yeast starter into the fridge. Received replacement 3-days later. Plugged in the new power adapter and it was back to life. Had to wait another day to pitch my yeast. Seems to work OK - I doubt this can pull the temperature down 20 degrees, but I just need 10 degrees so I can lager. A bit overpriced for what it is - but it beats having to deal with a glycol chiller for a small batch.
