Food Grade Non-Threaded Nitrogen Cartridges
Pure pharmaceutical-grade N2 — actually rare in cartridge form. Most "nitro" cartridges on the market are N2O (nitrous oxide). Our 2.4-gram non-threaded cartridges are pure nitrogen, the right choice for serious nitro cold brew and nitro coffee enthusiasts who want the cascade without any sweetness from N2O.
Why pure N2 vs N2O
- Zero sweetness: N2O carries a faint sweet note in some palates. Pure N2 is completely flavor-neutral.
- Pharmaceutical purity: Beverage-grade pure nitrogen — engineered for direct food contact.
- Same form factor: Standard non-threaded cream-whipper format — drops into the same nitro hardware as N2O cartridges.
- Welded closed: Engineered puncturable cap, welded sealed for shelf stability.

Frequently Asked Questions
How is this different from N2O chargers?
N2O is nitrous oxide — sweet undertone, common in commercial whippers. This is pure N2 — flavor-neutral, preferred by serious cold brew nitro enthusiasts. Both work in our Nitro Keg System.
How many cartridges per keg?
For a 128 oz nitro cold brew keg, plan on 2-3 cartridges depending on how nitrogenated you want the result.
