Change how you drink beer—and keep it fresh longer. This clever device uses a CO2 cartridge to ensure that the beer in your growler remains nice and carbonated, so you can enjoy a growler for days. Typically beer in a growler starts to get stale and flat after about 12 hours, just like a bottle of soda. This cap maintains a constant pressure inside the growler without introducing oxygen. A pressure-release valve on the end of the hose lets you tap it and pour one glass at a time, keeping the beer inside bubbly for weeks. Your GrowlTap comes with a disposable food grade CO2 canister that is good for five 64-ounce growlers' worth of bubbly beer.
Size: Designed for growlers with 1.75" diameter openings with 38mm thread; Tap is 4" in diameter x 1.75" H (without tubes); Inner tube is 10" L and outer tube (beer out tube) is 20" L; CO2 cartridge is 3.5" L and holds 16 grams; 1 CO2 cartridge is included, which will last for five 64-ounce growlers.
After each growler is finished, use warm soapy water to clean your GrowlTap; Open the tap faucet and allow water to flow through the hoses. Rinse with cold water. Hang the GrowlTap with the tap faucet open to allow water to drain out and air dry. Not dishwasher-safe.
When replacing the CO2 cartridge, use only 12 gram or 16 gram food grade CO2 cylinders, threaded or non-threaded. Non-food grade cylinders contain harmful byproducts like oil and benzene.
