Drinks gas & dispense

Nitrogen for nitro coffee, CO2 for carbonation, beer gas for dispense — plus regulators, couplers and cellar safety. None of it is a controlled drug.

Which gas does what — worth two minutes

These get confused constantly, and the confusion costs people money and occasionally gets them into trouble:

  • Nitrogen (N₂) — nitro coffee and nitro stout. Comes out of a restrictor plate as microbubbles. Food grade E941. Not a controlled drug.
  • Carbon dioxide (CO₂) — carbonation, post-mix and soda guns. Food grade E290. Not a controlled drug.
  • Beer gas — nitrogen and CO₂ blended, usually 70/30. Not a controlled drug.
  • Nitrous oxide (N₂O) — whipping cream, and nothing else on this site. This one is a Class C controlled drug and sits behind our supply policy.

Nitro coffee does not use nitrous oxide. If someone is selling you "nitro chargers" that turn out to be N₂O, they are selling you the wrong gas for the drink.

Cellar safety. CO₂ is heavier than air, colourless and odourless; a leak in an enclosed cellar can kill without warning. COSHH 2002 requires a written assessment wherever it is stored or used. A fixed monitor is not itself named in the regulations but is standard practice and increasingly an insurer's condition. Refillable cylinders are transportable pressure equipment — never accept one that is not in test.
