Typically you will use about 6g per litre of CO2 for carbonating and/or 6g per liter to dispense.

Perfect for parties where you're cranking out more than your average beer!

This CO2 Cartridge has a much larger thread than the standard 16g bulbs.

It will work with the Mini duotight Regulator without an adapter!
