Product Description

Cooling Jacket includes:  

   1) Cooling Jacket 

   2) Quick Disconnects

A patented design specifically made for home brewing and wine making.  Designed to allow accurate and reliable fermentation temperature control.  The flexible Cooling Jacket has over 320 square inches of cooling surface to make sure your fermenter stays nice and cool, and it totally encloses the cooling fluids so a heating element can also be used.  (Dimensions:  43.5” L x 13” H)

The jacket fits many common carboys and buckets (5, 6, and 6.5-gallon glass and plastic carboys, and 6 gal fermentation buckets), as well as conicals, variable volume tanks and other styles of fermenters.  If your fermenter is larger in diameter than a 6.5-gallon carboy (about 12.5-inches), add an Expansion Link to your Cooling Jacket.  

The Cooling Jacket is compatible with water and glycol.  Please note, the cooling jacket was designed to operate at 8 PSI or less.  Pressures in excess of 8 PSI may damage the Cooling Jacket.  In our tests, the March 809-PL-HS and 815-PL pumps worked well, as did the 370 GPH and the 500 GPH submersible pumps we use in our Advanced and Premium Kits.    NOT for use with Diaphragm pumps which can generate pressures over 8PSI (typically around 25 to 45 PSI) and will damage the Cooling Jacket. 


Quick disconnects are included with the Cooling Jacket (1/4" male and female, and 1/2" male and female) for connecting to 1/2" tubing. 

If you would like additional quick disconnects for your system, please see the links to Quick Disconnects.

Note: Carboy is not included.

  1. Temperature of liquid was better than expected 5 Star Review

    Posted by on 12th Aug 2019

    I used the cooling jacket on a 100 liter stainless steel variable volume tank. Set my Inkbird to 40 degrees Fahrenheit. In a hot trailer that usually was 95 degrees I was able to cool 22 gallons of water to 47 degrees. Later this summer it will have wine in it. Just wanted to check the cooling potential. Couldn’t be happier. Gotta brew came through.

    This product provides a simple way to keep my beer cool during fermentation.

  4. Quantum Leap In Fermentor Temp Control 5 Star Review

    Posted by on 18th Jun 2018

    Was using a mod. Sankey keg with copper tubing wrapped around it along with an insulating jacket. Consistent trouble keeping ferm temp at 65F (esp. when the ferm was at full blast). Switched to this cooling jacket and was astounded to find that the same chilled water system easily kept the ferm at 65F with half the ice block changes!

  5. great 5 Star Review

    i have used this product for several years now on ss fermenters...great well made product , can chill down to 2c using a chiller ,,gives good control over temps

  6. Jacket works great, and customer services is awesome 5 Star Review

    Posted by on 25th Oct 2017

    Received the jacket, extension piece, 500gph pump, and tubing. I set everything up on my Speidel 60L fermenter and a bucket with frozen milk jugs immersed in water, and brewed a 12 gallon batch of a Belgian Dark Strong / Quad with an OG of 1.108, and set it to work. Coupled with my temperature controller (a fermtostat from OhmBrew), a reptile-heating sheet, and a thermowell / blowoff tube assembly in place of the airlock, I was able to keep the temperature down in the mid 60's for 3 days, and started stepping it up progressively through to the mid 80's after a week.

    Unfortunately, later in the week, some of the heat-welds in the jacket "popped" out (the black circles that hold it's shape), and one of them sprung a leak. Fortunately, the beer was already fermented, so there was no loss of product. I contacted GottaBrew and Steve immediately sent a replacement, which I received within a week. I'm more than happy with both the customer service and the product, and look forward to many more brews.

  7. Worked great on 5.5 gal batch 4 Star Review

    Posted by on 10th Oct 2017

    The key is to insulate the fermenter! I used Reflectix from HOme Depot and just wrapped and taped it together.

    Fermenting a roggenbier currently and it went from 21C to 17.2C in a couple of hours. Along with frozen one gallon jugs, temps maintain just fine and just need to swap out every 12 hours or so.

  8. Dream Come True 5 Star Review

    Posted by on 17th Jan 2017

    If you are like me you researched fermenter temp control soon after you got serious about brewing. From 1 batch in a bucket and cooler to 5 batches in SS brew buckets in a keezer, to 10 gallon batches I have to say that brewing never felt so "pro" until I got the cool-zone setup. My hoppy pils is sitting steady at 55 degrees for 5 days so far. I have only had to switch out my frozen water bottles once and I have peace of mind that my brew is the right temp instead of guessing the ambient temp and hoping the wort matched. I could not be happier. I just ordered 4 more Sanke kegs and will purchase 4 more jackets with the extender as soon as my paycheck allows. Game changer!

  9. Should have been using this before 5 Star Review

    Posted by on 26th Oct 2016

    I have been home brewing for over 20-years without any temp control. Have to wait until the weather was just right and crank out a couple 5-gallon batches. Now I can brew anytime I want and it's all so compact. I integrated the Jacket into my insulated 6-gallon glass carboy, so that doesn't take up any space. I store the pump and controller in the 28-quart cooler, which just happens to be the perfect size for a 20lbs bag of ice. Right now one batch ferments for a week and it's roughly (2) 20lbs bags of ice per batch. I highly endorse this system for anyone that doesn't have room for a dedicated fridge for fermenting!!!

  10. WONDERFUL! 5 Star Review

    Posted by on 13th Sep 2016

    Perfect! Exactly what I was hoping for. It's very cool to see it fill with the cooling water and do it's thing!
