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

I bought two of these back in the summer. I was excited to get to use these new fermenters with the large openings to make cleaning easier. While they appeared well made, I encountered an issue when I went to seal up my first batch. One of my two fermenters sealed up great. It took a little problem solving, such as trying it wet, dry, with the gasket right side up, upside down. After a little fussing I was able to obtain a solid seal that held though the whole ferment. However, my second fermenter simply would not seal. No matter how tried to assemble the lid, it worked itself free, blew completely off, or got wedged in a way that allowed air transfer into the vessel. After getting through primary with the aid of tons of star San and plastic wrap, I inspected the opening more carefully. The glass necks were different sizes. Therefore my one fermenter will never seal properly. I contacted northern brewer immediately, and they offered round after round of pointless assistance. They suggested all the things I already told them I tried. They offered to send me another harness, as if the one it shipped with wasn’t good enough. I tried time and time again to explain the situation and that I wanted a replacement or a refund. My requests were ignored. I believe these are good fermenters, but for almost $80 a piece, I expected better quality control or at least better customer service. Be warned.

Big Mouth Bubbler® EVO 2 - 6.5 Gallon

Great large mouth glass fermenter perfect for 5 gallon batches with ample head space. Great if you are doing hop additions, coffee, bacon, etc. The lid that comes with this is not going to seal. I used tape to hold it in place, also bought the threaded lid. But know the small hole at the top of that threaded lid is small for most bungs. The Harness is a good addition.
