Small and mighty. Introducing the Draft Brewer® Cannonball™—the first ball-lock mini keg that packs the power of a draft system into a portable, compact 1.75 gallon barrel. Artillery for the small batch brewer. Carbonate homebrew in minutes, not weeks. Real-time carbonation control. A quick pressure adjustment and you’re instantly pouring perfect pints. The Cannonball™ blasts 3- and 5-gallon kegs out of the water. Barely bigger than a milk jug, it slides straight onto a fridge shelf, pops in a cooler or drops right into your trunk. From tailgating to camping, a picnic or a party, the Cannonball™ is the party-powering ammunition you need to have a good time, anytime and anywhere. Cannonball™ kegs are easily stackable once ball-lock disconnects have been attached.
