Ball lock kegs were originally commissioned by the Pepsi/General Beverage company for keeping and dispensing their soda brands from at restaurants and family centers across the world. When soda companies made the switch from kegs to "bag in a box" solutions, the market was flooded with these leftover kegs. Homebrewers across the country realized that they could use these 5 gallon vessels to store and serve their own brews from and the rest is history. We LOVE how kegging makes life easier and we know you're going to love any of the kegs you purchase from us. If you have a question and want to make sure you get the keg that's right for your situation, give us a call!
