Modular Keg Instructions

Also sold in a 5-gallon size!
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. Its 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.

  • Keg Top and Keg Base

I was looking for a small keg I could take to parties of stuffing the fridge. This seems to be the perfect answer, and because it is modular I can takeout apart to clean it, and can add the center section tp go from 1.75 to 5 gallons when I want to. Pretty great right?

Well built unit

This is a very well built unit. The first time I used the keg I had a slight leak from the center gasket - tightened it a bit more and it solved the problem. Very easy to clean. Mine also came with the posts reversed, also a quick fix. I bought the expansion kit, but haven't used it yet.

Size not 1 gallon

The description states that the keg is 1 gallon. I measured the volume that it holds and it came out to a couple cups over 1.5 gallons. I was really looking for a 1 galllomg keg. Not a 1.5+

Great purchase for specialty uses

High Quality unit, the smaller size allows me to experiment with different brews and levels of carbonation. Northern Brewer has been excellent to work with. Have not purchased the expansion kit yet, but does make for a great option in the future.

Neat toy, but gas and pour post reversed

went to use it for the first time and when I hooked of the gas line I heard bubbles, I learned they had the post reversed, so check before kegingOverall, very nice keg, great for the park or showing up to watch a game with your own keg, out does everyone else......
