What the maker puts in writing

  • Food grade and beverage grade, non-lubricated CO2
  • 16 gram threaded cartridges, standard 3/8-24 pitch
  • For cocktails, seltzers, kombucha and carbonated growlers
  • Also compatible with most CO2 bike tire inflators
  • 6-pack

Two dollars sixty-seven

That is $15.99 divided by six, and it is the highest price per cartridge on this shelf.

Here is the whole shelf, on the makers’ own prices and counts:

  • Asura 30-pack — $1.05
  • RedRock 30-pack (unthreaded) — $1.17
  • ICO 50-pack — $1.18
  • Asura 20-pack — $1.35
  • ICO 10-pack (unthreaded) — $1.80
  • TrailKeg 6-pack — $2.67

When the small pack is the right buy

Once: when you do not yet know whether your dispenser takes a threaded cartridge.

Sixteen dollars to find that out is cheaper than fifty-nine dollars of the wrong fitting.

What readers ask us

Threaded or unthreaded — how do I know?

Look at the cartridge your dispenser came with: a threaded one has a screw thread cut into the neck, an unthreaded one is smooth and gets pierced. They are not interchangeable. This is a threaded 3/8-24 cartridge; two items on this shelf are unthreaded.

Why is it the most expensive per cartridge?

Because it is a six-pack. Small packs cost more per unit everywhere, and on this shelf the difference is two and a half times: $2.67 here against $1.05 for the 30-pack. If your dispenser is threaded and you know it, buy the big box.

Does non-lubricated matter?

For a drink, yes. Some industrial CO2 carries trace lubricant from filling, and that is what people mean when they complain of a taste. TrailKeg states non-lubricated; ICO states EU food standards and no metallic aftertaste. Both are addressing the same worry.
