These pure nitrogen bulbs have a slightly different effect on cold brew coffee or espresso martini etc served in our nitro mini-keg system.
You will need more bulbs than using N2O and you will need to either shake it harder or leave it to absorb for longer into the drink before pouring. However once absorbed the drink will pour with a cascading head like a Guinness stout with zero effect on flavour.
N20 bulbs, on the other hand, you can inject, briefly shake and then pour instantly. They impart a very slightly sweet flavour and produce a drink with a dense head and a body that settles quickly to look like an espresso martini.
Either bulbs can be used in our nitro bulb injector keg systems, it is up to your personal preference.
Neither N2 or N2O bulbs are for use with our mini regulator, it is only for CO2.
