Changing a keg may seem like a complicated process, but with the right steps and best practices, it can be an easy and rewarding task. In this article, we’ll walk you through the basics of changing a keg, including releasing the pressure, disconnecting the old keg, sanitizing your kegerator and the new keg, connecting and locking the coupler, and finally pressurizing the system.
The first thing you’ll want to do is shut off the gas supply. This can be done either at the main regulator near the keg or, depending on your system, at each individual coupler. It’s also important to remember that you should always practice “First In, First Out” when kegs run empty. This ensures that you sell the oldest kegs first and keeps your inventory at peak freshness.
Once the keg is disconnected, locate the replacement and break open the security seal (for Sankey (D and S System) or slide in the keg tap before pulling down on the lever to lock). Make sure to double-check the fullness and that the beer inside is within the best-before date.
After you’ve seated the coupler, turn it clockwise until it locks into place. You shouldn’t have to twist very hard, but it should be tight enough that you feel resistance. Then, make a quick check for leaks by opening the tap and letting the beer flow out for a few seconds.
Once the new keg is connected and you’ve adjusted the regulator pressure (to 12-14 psi for straight Co2 or 20-25 psi for a blend of Co2 and Nitrogen), it’s time to start serving beer. But before you do, be sure to give the keg a good shake and a couple of pumps to evenly distribute the gas.
