Description

Have you been struggling with fermentation temperature swings? The BrewBuilt Neoprene Carboy Sleeve works great for maintaining the internal temperature of your 5, 6, or 6.5 gallon glass carboy. If you aren't fermenting in a temperature-controlled environment your beer is likely rising and falling with the ambient temperature, and these swings can stress out yeast and have a negative effect on the finished product. This 6 mm thick neoprene sleeve will help retain the heat naturally produced by fermentation activity and provide some protection from the ambient environment, leading to more consistent fermentation temps, happier yeast, and less off flavors in your beer.

We highly recommend the neoprene sleeve for use with the BrewBuilt Carboy CoolStix. The added insulation will lower the amount of cycles needed to maintain fermentation temperatures and is a must-have for cold crashing.

For carboys, don't have temp control chamber yet.

Need insulation for my ferm temp control system
Michael Murdy on Aug 13, 2020
Is there any reason this wouldn't work as kettle insulation for a 5-6 gallon kettle (Like the SS Brewtech)? I do electric BIAB and the dimensions are almost perfect for that application. With an induction cooktop I doubt the kettle would get hot enough to melt the neoprene. Thoughts?
Tysen Bibb on Apr 17, 2020
BEST ANSWER: This should work fine for that application since you are using an electric heater. Neoprene seems to have a burn/melting point over 250 degrees fahrenheit so it should be safe. That said I do recommend watching it diligently for the first few brews and you should always have a good fire extinguisher at hand any time you are brewing with any system just in case.
Would it work for a 6gal plastic car boy?
Thomas Ratliff on Feb 23, 2021
BEST ANSWER: It's a little tight, but works fine for my 6 gallon glass carboy, and my 6.5 gallon glass italian carboy. So I imagine it should be fine for a plastic one. Note you'll probably still want something to insulate underneath as well.
Does this fit the 7 Gallon Fermonster?
Colten Zachary on Apr 28, 2020
BEST ANSWER: The size you will want for the 7 gallon fermonster is the FE329C made for the 6.5 gallon glass carboy. The Fermonster is 11.3" diameter and the jacket will stretch that last 0.1" to snuggly fit the fermonster.

Pretty good insulator
Together with a stainless insert, the sleeve allows me to reach an external temperature in a carboy onky about 6° higher than my lagering chamber. Nice.
