Cornelius Keg Dimensions

Cornelius kegs, which are frequently used by homebrewers as a substitute for bottling their beer, were initially created by the soft drink industry. Even if Coca-Cola and Pepsi have used them, those who make their beer or soda at home have helped them gain popularity. They are simple to clean and fill. 

The Cornelius keg can be connected to two different types of connectors: pin-lock and ball-lock. You would need to get used to the many connectors that each has.

This size keg, which is intended for mini kegerators, can only hold 5 liters of beer, or precisely 169.07 ounces. This size keg is ideal for occasional use and portability. This could be hosting a modest dinner party for family and friends, going camping for the weekend, or watching the game with a few buddies.

Sixth Barrel Dimensions

The sixth barrel, frequently utilized for personal use in dual or triple-tap kegerators, is similar in size to the Corny Keg but a tiny bit bigger. This smaller-sized keg performs the same functions as its larger counterparts; the only distinction is that it can hold less beer than other keg sizes. This size keg is also a wonderful option for bars and/or restaurants with limited space but a high demand for a wide beer selection.

  • Capacity: 992 ounces / 7.75 gallons
