ABOUT THE GROWLER SAVER
The Growler Saver is a growler cap system (Patent Pending) that ensures the retention of carbonation and flavor in beer stored in a growler, even if the growler has already been opened!
Until the development of this cutting-edge industry-first design, draft beer stored in a growler could not retain its optimum freshness and the brewer's intended carbonation levels, especially after the growler's original seal was broken.
Now, thanks to the Growler Saver, beer drinkers no longer have to consume an entire growler once they open it for the first time, or otherwise risk their beer tasting old, under carbonated, or exhibiting off-flavors. With the Growler Saver, beer drinkers can open their growlers again and again, with the confidence that the beer inside will taste just as good as it did when it left the tap.
The Growler Saver consists of two primary components: an injector device and the actual growler cap. The injector device accommodates 16 gram threaded or unthreaded CO2 cartridges, as well as 12g threaded cartridges. The injector device couples with the unique food-grade Schrader valve on the cap, allowing CO2 to be injected directly into the growler vessel through the cap with a brief squeeze of the trigger.
The second valve on the cap is a pressure-relief valve that is calibrated to 15 pounds per square inch (PSI). This valve acts as a safety mechanism by governing pressure within the growler headspace to the 15 PSI threshold. This maintains a beer carbonation level that is within a reasonable tolerance for most popular beer styles. As the second video on our page demonstrates, you can also measure the PSI in the headspace with a standard tire gauge and dial in an exact PSI level below the 15 PSI threshold, if the beer style dictates a lower carbonation level.

"I wanted to let you know the Growler Saver showed up as promised and I really like it. We used it this weekend and have since made a trip to the local brew pub for a growler refill. It sure makes drinking fresh draft beer more enjoyable knowing you don't have to finish the growler in one sitting.
You never know, I may need to order a second one. Thanks for the great product."
