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

It may have variations in shape and thickness, and will show the normal bubbling characteristics of hand-formed glass. Extreme changes in temperature or sudden contact with hard surfaces may cause glass to crack. Handle with care. We strongly recommend using the Northern Brewer Universal Harness for increased safety and ease of handling.

*Pro Tip: Save your box and use it as a cover for your fermenter!

Just like it's advertised

It's a carboy, made of glass, w a big mouth.
Only thing I was disappointed w and gave 3 stars is because the carrier is loose and not well designed. I bought another brand that isuch better but is made for a standard carboy.

I own a clinic specializing in Chinese medicine and when we found these products our hopes were realized. We make an herbal product called Dit Da Jow, it has been used by martial artists for hundreds of years to address injuries sustained while training. To make it we age Chinese herbs in an alcohol called Baijiu. Baijiu is a distilled from fermented rice. The aging process takes years and was historically done in massive clay jugs. These Big Mouth Bubblers are a great modern alternative. They hold up to the aging process in a way plastic would fail, we can watch the aging process as it goes, and best of all, we can easily get the herbs out when the aging process is complete. We've got six going right now and will be soon expanding our operation to allow for many more batches to age at once. I just can't say how happy we are to have found these Big Mouth Bubblers years ago.
