Big Mouth™ Modular 1 Gallon Keg

SKU: 41501



The first-ever expandable 1-gallon keg!

Introducing the first keg purpose-designed for homebrewers. The Big Mouth™ Modular 1 Gallon Keg packs the power of a draft system—and then some—into a portable, compact 1-gallon barrel. Slide it in your fridge. Pop it in a cooler. Share, anywhere.

  • 1-Gallon size is perfect for the fridge and easy transport
  • Withstands up to 40 psi of internal pressure
  • Completely breaks down for easy cleaning
  • Expandable to 5 gallons (with optional expansion kit)
  • Crafted from heavy duty 304 Stainless Steel to last a lifetime

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 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.

We recommend a 7/16" wrench or deep socket for tightening the V-Band Clamp.

Also sold in a 5-gallon size.

1 Gallon Keg Kit Includes:

  • Keg Top and Keg Base
  • V-Band Clamp
  • Silicone Center Gasket

Dimensions: W: 11" with V-band; H:11"
