If you're dispensing with a Keg Cap®, you've probably wondered how many pours you can actually get out of a single CO2 cartridge -- and whether you can swap in nitro for a creamier pour. Here's what our own specs say.
How Long Does One Cartridge Last?
With CO2, less is more -- it's a lot easier to add more gas to your growler than to remove too much, which causes foam and makes it hard to control that perfect pour. With the Keg Cap®, it only takes a quick half-second "open-close" of the CO2 injector to charge the growler with enough gas to dispense.
With appropriate charging, one 16-gram CO2 cartridge lasts for two to three full fills of the 64 oz Craft Growler, or one to two full fills of the 128 oz Craft Growler. We recommend pouring directly from the 32 oz Craft Growler rather than using dispensing equipment on that size, since CO2 dispensing needs at least 10 oz of head space to function properly.
Can You Use Nitro?
No -- only 16-gram, threaded, non-lubricated food-grade CO2 cartridges are compatible with the Keg Cap®. Never attempt to use nitrogen gas with the Keg Cap® or any of our current products. If you're not sure a cartridge meets these requirements, our CO2 6-pack is guaranteed to work.
