Product Details

Designed to be dynamic. The Big Mouth Bubbler Harness can be grabbed anywhere on its adaptable frame without worry of slippage, making every stage of the brewing process easier on you and your fermenter. Whether lifting, transporting, pouring, sanitizing, storing or just sitting, the Harness holds tight to its Big Mouth passenger- keeping you, your brew, and your Big Mouth Bubbler safe, however you prefer to handle it.

Engineered to last. Constructed from the same material as harnesses that are used to summit the world's tallest mountains, the Big Mouth Harness is hardy enough for even the most extreme homebrewing conditions.

Fermenter handling, foolproofed. Tirelessly tested to ensure usability, the harness construction includes color-coded areas so you know exactly how to strap in and secure your Big Mouth Bubbler. No confusion, no worries.

The Big Mouth Harness was designed in tandem with the Big Mouth Bubbler, a product of the same innovation and passion for making homebrewing easier. And by making it locally, our engineers were given the flexibility to customize, test and tweak every detail of the Harness' construction along the way. This journey has resulted in the toughest homebrew handler on the planet, equipped with enough strength and durability for climbing mountains with this harness, though we recommend using it for your Big Mouth Bubbler, since that's exactly what it was designed for (and fermentation temperatures aren't exactly ideal atop Everest).

Must have
Don't get a BMB without it. I do wish the straps lined up with the spigot better on the ported version of a BMB (still usable though).

Essential Item
This thing is essential for lifting my fermenting cider out of my chest freezer and putting it back in without killing myself or dropping/spilling the contents.

wonderful addition
there are other harnesses out there, but this one fits the 6.5 gallon carboy with a nice adjustment system. Because this carboy is PET plastic, it will flex if you try to "hug" it to lift it and then your cider/beer/wine will squirt out of the top with good velocity. use a harness, this is a great one.

Works as intended
Not much to say about the harness. It works fine. Makes moving a full fermenter around much easier.

Love it. The harness is easy to use, makes the bubbler very manageable. Wouldn't buy the bubbler without a harness.

I've seen different statements that this doesn't fit a 6.5G ported BMB. Northern has said No, owners say Yes. Any final response? Also, has anyone used with a fermwrap underneath the holder? It wraps around about 80% of the circumference.

BEST ANSWER: Northern brewer brewmsater here! It fits perfectly, the spigot should not be in the way.
Will this harness work with the ported bmb?
JB on Nov 7, 2015

Unfortunately the harness will not work for the ported BMB because the lower strap goes right over where the port would be. Maybe I should have a talk with the boys in R&D because that seems like something that could be changed to accommodate the ported version.
The pictures of this item show a blue threaded ring on top. I need 6 of these. Where do I find the rings?
Glenn A on Dec 27, 2017
BEST ANSWER: That is the top to the Fermenter Glenn. Just buy 6 new tops. Do you have 6 fermenters without tops? If so, this is your answer.
Why does it say Not a carrier?
stan s on Feb 17, 2016
BEST ANSWER: The line is 'not a carrier, this is a harness'. Implying that its heavier duty than a carrier with a more secure fit. All true. I like that the straps criss cross around the top holding the Bigmouth very securely. If I had more Bigmouth Bubblers I woukd get a harness for each one.
Will it work for both 5L and 6.5L plastic Bubblers?
J K on Jan 30, 2016
BEST ANSWER: To be honest I haven't put the harness on my 6.5g bmb. I will tell you the there is an adjustment strap on it
Will this work with the siphon less big mouth bubblers?
C A on Dec 27, 2015
BEST ANSWER: Yes it does work with siphonless models
What is the height and depth of the 6.5 gallon bottle?
I R on Mar 2, 2016
BEST ANSWER: The 6.5 gallon big mouth bubbler is about 22" tall and it has a diameter of about 11"
