The Growler Saver will keep your growler of beer carbonated, and tasting like it came straight from the tap for days on end.
Watch the Updated Video below for more details.
What is the Growler Saver?
The Growler Saver is a Patent Pending cap that will ensure a draft-like beer pour out of a growler, even after breaking a growler's original seal and opening it numerous times. Until I developed 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 full of 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.
What is the concept behind the Growler Saver, and How Does it Work to keep beer fresh and carbonated?
The Growler Saver applies similar principles and processes that brewers and home brewers use when they fill kegs. The simple design of the Growler Saver first allows consumers to inject CO2 directly into their growlers. After injecting their growlers with CO2, users then manually open the built-in relief valve and discharge all of the air and oxygen out of the growler's head space. CO2 can then be re-injected as necessary. This process creates ideal conditions for storing the beer inside the growler, and will ensure lasting freshness and carbonation. The Growler Saver's relief valve will also prevent the Growler from being over pressurized, while at the same time working as a safety valve that will relieve pressure that exceeds a preset factory setting.
Can the Growler Saver re-carbonate flat beer or a growler that was not filled to optimal conditions?
Yes, in addition to ensuring lasting freshness and carbonation, beer drinkers can use the Growler Saver to re-carbonate beer inside their growlers. Most of us have experienced a flat growler, even upon its initial opening. The trusted principles behind the Growler Saver's design will allow users to re-carbonate their beer and turn it back into the beverage that was intended to be enjoyed right out of the tap.
How has the Growler Saver been tested?
The Growler Saver was first developed roughly two years ago, and has been put through a series of rigorous tests since it's original prototype design. These tests include side-by-side comparison studies with growlers using a standard cap versus growlers using the Growler Saver. I have also performed many hourly interval tests. These interval tests include pouring 12 ounces of beer each day from a growler with a standard cap and a growler with the Growler Saver at 24, 48, 72, and 96 hours post-fill. Each growler is opened side-by-side at each interval and are stored under identical conditions, except for the difference in cap. The results of these interval tests have demonstrated again and again that the Growler Saver keeps growlers significantly fresher than a standard cap. In fact, such tests show a significant difference in taste and carbonation after only 24 hours. My testing indicates that beer stored in a growler with a standard cap begins to break down and oxidize as early as a few hours after the initial seal is broken. Beer stored in a growler utilizing the Growler Saver tastes fresh and properly carbonated for weeks.
In addition to conducting freshness and carbonation tests, I have put the Growler Saver through a series of rigorous mechanical tests that have helped to ensure that the device is easy to operate, safe, and will consistently perform it's intended function. I have incorporated both medical and industrial technology into my design, and have strove to source nearly all components that are manufactured in the USA. Much the same, all Growler Savers have been prototyped and will be fully assembled in the USA.
What materials are the Growler Saver made from and Is it easy to maintain and keep sanitary?
The Growler Saver has been designed for optimum function, with medical-grade and food-safe components. Essential to the Growler Saver's ability to keep a beer as fresh as it was out of the tap is the fact that its design eliminates any materials or hoses coming into contact with the beer inside the growler. This design feature is critical to ensuring that the beer is not contaminated or infected. It has the added bonus of making the Growler Saver very easy to keep clean. The Growler Saver can be hand cleaned with soap and water, or most beer sanitizing solutions or any other readily available food-safe sanitizer.

I have conducted extensive networking that has lead to the development of many great relationships with local facilities. Through these relationships, I can ensure that my final product will be manufactured and hand-assembled to the highest standards by American workers. However, I need your help with funding in order to set up the tooling and purchase the necessary materials to produce a large quantity in order to keep the final price at an affordable level.
The main cap is designed to be used on screw top 64 oz. growlers. However, I have designed a series of adapters that will convert the main cap to many types of growlers, including wide mouth swing top and long neck, bulb shaped swing top growlers. These adapters will be made available once the main system is funded, and will be under $10 each. I will also be offering a master adapter kit which will include adapters for the common varieties.
The current washer is made from Food Grade, FDA Grade, Buna-N/NitrileRubber
Yes, you can keep it connected, I designed it to be removable in order to keep the design compact.
What keeps the Growler from becoming over pressurizing beyond a safe level while using the Growler Saver?
The Growler Saver has a built in pressure relief valve that will automatically bleed off pressure that exceeds a preset psi level. This ensures that the growler will not become over pressurized. If you view the video just past the 2:30 mark, you can see how the relief valve automatically opens and vents off pressure.
I already have my machine shop and manufacturing all set up and ready to go, so you will not have to wait long at all. Once the project is funded, I will purchase the required materials and all orders will be shipping out in June.
It will not be charged until the end of the campaign, as long as the funding goal is reached.
