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. Versatile and convenient! 5 Star Review

    Posted by on 19th Oct 2020

    This is a fantastic product I bought this to use with half barrel kegs that have been converted to fermenters. And with the use of a diy glycol chiller I have no issues holding fermentation temps, or cold crashing in a 90 degree garage.

  2. It works! 5 Star Review

    Posted by on 16th Jul 2020

    This thing works great. And it's surprisingly fast in it's operation. I have it hooked up to a mini-fridge I modified to cool a 33% glycol solution. It maintains temperature like a champion set up on an InkBird thermostat controller. I wrap everything with a towel, which - while it doesn't provide optimum insulation, does prevent/absorb sweat which is nice. Might eventually pair this with the insulated jacket also sold by Gotta-Brew. They're local to me, so I'll just shoot over there some day!

  3. I now have four of these. 5 Star Review

    Posted by on 14th Jul 2020

    I have four of the cooling jackets which I love. Running off of a Icemaster Max4 glycol chiller. I can lager in keg or carboy, can chill to serving temperature in keg, and can control fermentation in fermenter. I am using primarily with corny kegs. Using jacket around keg and using CoolBrewing insulated keg cooler bag.

    Very happy.

  4. 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.

    Thanks guys at Gotta-Brew the 2nd cooling jacket arrived before Easter with no courier issues. I now have two cooling jackets set up on 2 x 100L stainless steel tanks, cooling white wine.

  6. cooling jacket 4 Star Review

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

  7. 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!

  8. great 5 Star Review

    Posted by on 17th Apr 2018

    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

  9. 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.

  10. 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.
