We have a ball lock fitting valve that fits a 2 liter soda bottle. You can fill the soda bottle directly from your keg, and then pressurize with your CO2 line ball lock quick disconnect. Cool right? Once pressurized, the carbonation is not lost until opened. Great for taking draft beer to parties, picnics, games or wherever without it going flat. Made by Liquid Bread.
You can also use it for carbonating your own soda, water, tea, or juice. Just turn your CO2 regulator up to 35 PSI, fill with water, soda or other beverage and shake for a minute. The key is to make sure your beverage is very cold (cold liquids absorb CO2 much faster) Very easy to carbonate using the Gas connection on your homebrew keg setup. Great product!
