The North Mountain Supply 4 Gallon Graduated Fermenting Bucket with Twin Bubble Airlock and Grommet is a practical, easy to use fermentation vessel for homebrewers, winemakers and fermenters who want a bit more capacity than typical starter kits. It is well suited for small to medium batches where you still want manageable size and convenient handling.
The bucket features molded graduation marks up to 4 gallons and 16 liters. These volume markings make it simple to measure your batch size, mix top up water and track transfers or additions with better accuracy, which is especially helpful when you are scaling recipes or repeating successful brews.
Included with the bucket is a twin bubble S style plastic fermentation airlock and a grommeted opening in the lid. When the airlock is filled and seated in the grommet, it allows carbon dioxide to escape during fermentation while helping to keep outside air, dust and unwanted microbes away from your beer, wine or vegetable ferments. This classic setup offers a low maintenance way to manage active fermentation without constant attention.
All components in this set, including the bucket, lid with grommet and twin bubble airlock, are made from high quality plastic and manufactured in Italy. The smooth interior surfaces clean easily and are compatible with common brewing and winemaking cleaners and sanitizers when used as directed.
The 4 gallon capacity offers flexible options, such as:
-
Primary fermentation for small to medium batches of beer or wine
-
Experimental batches where you want enough volume to share but not a full 5 gallons
