CO2 Threaded Beverage Grade Cartridges - 16 Gram
The standard cartridge for the Premium Draft Mini Keg System. One 16-gram beverage-grade CO2 cartridge dispenses a full 128 oz keg with pressure to spare. Available in 5-, 10-, and 30-pack sizes so you can stock up to match how often you keg.
Why beverage-grade matters
- Pure taste, every pour: Brewery-spec filtration means no industrial off-flavors. Your beer, cold brew, or cocktail tastes like itself.
- One cartridge per keg: A single 16g cartridge handles a full 128 oz mini keg start to finish at typical serving pressure.
- Threaded for clean swaps: Hand-thread into the regulator. No leaks, no fumbling.

Frequently Asked Questions
How many pours does one cartridge get me?
One 16g cartridge dispenses a full 128 oz mini keg (about 8 pints) at typical serving pressure, with margin to spare.
What's the difference between food-grade and industrial CO2?
Food-grade (also called beverage-grade) CO2 is filtered to higher purity standards. Industrial CO2 can carry trace contaminants that affect taste — fine for paintball or welding, not for what you drink.
Can I use this with the Nitrogen Mini Keg System?
No — that system uses non-threaded nitrogen cartridges, not CO2. Use these with the Premium Draft CO2 Mini Keg System.
Pairs Well With
