Pressurized CO2 Growler Dispenser Tap for Glass Beer Growlers by the Spotted Dog Company
This setup consists of a regulator, growler dispense cap, faucet with tubing and dip tube. It’s designed to fit standard glass growlers. This allows you to serve tap beer from a standard growler as you want to. Since it’s regulated, you can keep carbonation levels up and reduce oxidation. Note that a growler is not included and you need to buy CO2 cartridges separately.
Hands on Review: Spotted Dog CO2 Pressurized Growler Dispenser
A look at the cap, faucet and tubingA look at the included mini CO2 regulator. Note that this is a regulator as opposed to an injector. Injectors give you no regulation of pressure other than the amount you choose to inject. This is an actual regulator that you can set to a desired pressure. That’s a key feature since this is intended to be used with compatible glass growlers.
You can also use this with your homebrew keg… This regulator features a female flare connector (the brass piece on the right side of this photo). That means you can install it on a ball lock or pin lock MFL QD [Search MFL keg disconnect] and use it on a ball lock or pin lock homebrew keg. Whammo!A look at the faucet. A standard picnic/cobra style tap with a small length of tubing attached.A look at the inside of the dispense cap. Notice the included o-ring/gasket. The cap feels sturdy and well built.A look at the cap top-down. A PRV is installed on the top of the cap. That’s for venting to help adjust pressure or when you’re ready to remove the cap. The male flare at the bottom is for installation of the included regulator.A look at the entire assembly after a soak in PBW. Note that I did not soak the regulator in PBW. That was installed after cleaning and rinsing the cap, faucet, tubing and dip tube.Installed on a growlerA look at the front of the CO2 pressurized growler dispenserA close up of the regulator dial. The gauge on this regulator reads 30 PSI. Under no circumstances should this be set at 30 PSI. I keep it under 10 PSI. For serving I’ve found that just 1 or 2 PSI is sufficient. It’s important that you read and follow all manufacturer’s instructions for this unit.

I keep it under 10 PSI. For serving I’ve found that just 1 or 2 PSI is sufficient. It’s important that you read and follow all manufacturer’s instructions for this unit.A look at the PRV valve
The picnic tap hangs nicely on the growler handleI found this easy to clean. After removing the regulator, I rinsed the entire assembly, making sure there was some water left in the faucet tubing to help start a siphon. Then I placed the unit in a tub of PBW and opened the faucet (below the unit and tub of PBW). That starts a nice flow of PBW that you can let run out. Of course, I did all of this in my Gridmann Commercial Stainless Sink. I consider a quality utility sink an essential piece of homebrew gear.
Beyond standard growlers this will work with other compatible growlers that use standard 38mm caps. Examples: The Prowler PET Growler and 128oz Stainless Steel Insulated Growler by Spotted Dog Company. It will also work with some gallon size jugs as long as they are pressure capable and use standard threads. For the larger gallon containers, you may need to swap out the dip tube tubing for a longer length.
The beauty of this setup is that it works on standard glass growlers. Many locales or breweries only fill their branded or specially marked growlers.
This does have some safety implications, it’s important that your growler is in good condition and capable of holding pressure. That’s always true whether you’re using this or not. Growlers hold pressurized beer and should be capable of doing so at proper pressures. Make sure to read and follow the directions that come from the manufacturer and set this to a safe PSI for your particular growler. The good news is, not much pressure is needed to serve beer. As I’ve already mentioned… you don’t need a lot of pressure to serve beer with this, just a 1 or 2 PSI.
This allows me to preserve beer, commercial or homebrew, using an easy to find standard growler so that I can drink it at my own pace. This is well built and converts a compatible growler into a featured packed mini keg that helps to preserve beer so you can drink it at your desired pace.
