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

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.

Please note: This item does not qualify for flat rate shipping.

Product Details

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 adhesive fermometers 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.

Note: We still strongly recommend the Big Mouth Bubbler® carrying harness.

Each Big Mouth Bubbler® Includes:

  • Big Mouth Bubbler® Glass Fermentor, Universal Lid*
  • Big Mouth Bubbler® Microfiber Cleaning Cloth

*The new Big Mouth Universal Lid (included) fits all Big Mouth Bubbler® Fermentors. 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. Ribbed silicone rings ensure 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 fermentor.

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

Caution: Big Mouth Bubbler® is a large hand-formed glass item that can be easily damaged if not used with proper care and handling. 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 Big Mouth Bubbler® carrying harness for increased safety and ease of handling.

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

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.
