Big Mouth Bubbler®
The easiest vessel to get clean & keep clean.
When you put your brew in a fermentation vessel, your ONE expectation is that it will stay clean and that your yeast will be able to eat happily without anything funky going on. A strictly non-funky fermentation party. That’s it. But how can you expect the cleanest and safest fermentation environment when you can’t even scrub the bottle with your own two hands? This vessel was designed especially for sanitizing and fermentation.
Designed for brewers—by brewers!
Brewing can be a messy business—but no more! Stick your arm in to clean the entire inside with the swipe of a cleaning cloth. No need to use an inefficient carboy brush to reach corners and curves. Enjoy total confidence that every hint of bacteria is gone, protecting your investment in brewtime. The wide-mouth makes it easy to add or remove ingredients. The universal lid guarantees the top stays on through fermentation.
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. 5 gallon fermenters are best for the secondary conditioning stage of beer fermentation. The smaller size eliminates extra airspace in the fermenter reducing the chances of oxidation which can stale the beer prematurely.
