Big Mouth Bubbler® EVO 2 - 6.5 Gallon Fermentor is a revolution in homebrewing!

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. Say goodbye to that awkward brush and give your fermentor the deep-clean your beer deserves. Scrub off any unseen biofilm. Effortlessly wipe away crusted krausen in just a couple of carefree minutes. 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! 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.
