How does the Carbonater™ valve coupling work?
The Carbonater™ fits on a standard 2 liter plastic soda bottle in place of the original cap. It uses a standard beverage fitting (the kind found on Pepsi style soda kegs). This allows for the purging of air, after gently filling from your tap, then injecting up to 30 psi (max), giving you a 100% CO2 head-space. This method gives you a shelf life similar to the beer remaining in your keg. To simply maintain carbonation in an already carbonated product, set your pressure at between 5 and 10 psi. To carbonate an uncarbonated beverage, set for 30 psi. For more information, please see our Carbonater™ instructions.
