Product Details
When the party is over, Big Mouth™ completely disassembles to fit in a dishwasher. Effortlessly clean every nook and cranny.

Modularity means more than just a cleaner, more sanitary keg. It’s expandable. Start with the mini-keg for small batches or quickly kegging and carbonating a partial batch. Pop in the optional 5 gallon expansion pack (sold separately) when you’re ready for bigger brew days, and collapse back to 1 gallon for keeping it in your fridge or party-ready portability.

Equipped with a revolutionary access port for easy flavor additions. Hang a hop bag or oak spiral from the included hook to customize any batch. Plus, the smaller port means easier sealing and less chance of oxidation.

Collapse it. Clean it. Customize it. The Big Mouth™ Modular Keg is designed for sharing premium homebrew at its prime, from the first batch to the five-hundredth.

Also sold as a 5-gallon Keg.
