Product details

The fermenter that started it all, reinvented again! We've taken the revolutionary 6.5 gallon Big Mouth Bubbler® glass carboy and re-engineered it with the help of world-class Polish master glassmakers to ensure sturdy, solid, superior craftsmanship.

6.5 Gallon fermenters are perfect for the primary stage of beer or wine fermentation. The extra head space allows for the production of krausen on a 5 gallon batch of beer. Also available as a 5-gallon secondary fermentor.

Extra-thick glass eliminates oxygen permeation and keeps your brew safe. Banish bugs and bacteria with perfectly air-tight seals from a carefully ground, completely smooth and obsessively flat neck top.

In the evolution of Big Mouth Bubbler®, we've added some perks! Instantly measure volume with gallon graduation marks. Easier transfer of clear beer with a taller, narrower body while ensuring less liquid is left behind.

Bid your funnel and siphon sayonara! Pour cooled wort directly from your kettle into the Big Mouth Bubbler® for instant transfers. Pitch yeast without it running down the sides of your fermentor. Easily add flavorings to secondary, and then just as easily remove them!

Gallon graduation markings help ensure precise measurement of fermenter volume.

Last but not least, you asked and we listened: more space for the adhesive FermagraF° LCD thermometer than any other glass fermentor! The most obsessively engineered glass fermentor ever created, we are proud and excited to introduce the new and improved Big Mouth Bubbler® EVO 2.

Now Includes the Northern Brewer Universal Harness for lifting, transporting and ensuring your Big Mouth Bubbler lid stays firmly in place during even the most intense fermentations.

Each Big Mouth Bubbler® Includes:

  • New Big Mouth Bubbler® Universal Lid
  • Carrying Harness for Big Mouth Bubblers®

The new Big Mouth Bubbler® Universal Lid fits all Big Mouth Bubbler® Fermenters. The Big Mouth Bubbler® Universal Lid is just like a traditional carboy bung, only bigger! Just as easy to sanitize and set in place too. Removable ribbed silicone ring ensures a positive seal to keep out pests, while the non-threaded design allows the lid to move preventing an out-of-control fermentation from dangerously pressurizing your fermenter.

You will also need a Small Universal Carboy Bung - drilled or solid

Lid doesn't have a tight fit

I bought this for large batch kombucha brewing. It came with a weird harness that moves when you lift it and lacks stavility. The lid sits on top of the jar instead of threading with the glass, so it has a really loose fit. The jar is fine though.

Great fermentor.

Aside from a few little annoyances, this thing is pretty great. It can be a little tricky to get the gasket on the lid seated, but after some trial and error, it is in there nice and snug. Dry off the inside of the bung with a paper towel and twist the lid as you are putting it in, and with a little fines it will seat very securely.
Also, because this thing is nice thick glass, it is pretty heavy when full. The included harness needs a little help to be confidently secure. I set it up and marked where the adjustable straps intercept, then sewed them in place to insure no slippage. Even with the need for some inside knowledge and need for modification, I think that this fermenter is one of my favorites for non pressurized fermentation.

Improvement over Standard Carboy

Very pleased with this product. Just finished my first batch’s primary feementation in it. Cleaning the Big Mouth is SO much easier than cleaning a standard carboy. You can use a sponge to scrub off the krausen - much easier than using a bottle or carboy brush.

Excellent product. Made with high quality glass and with the wide mouth it is a breeze to clean afterward. Already brewed an Irish stout and a Hefeweizen using it and I loved it!
