The first thing you need to do is make your cold brew coffee.
To do so you need to mix your preferred ground coffee with water
The ideal ratio for me is 1/2 cup of ground coffee to 4 cups of water
this will give you around 1 liter of strong coffee
Next, you need to let the mixture steep for at least 12-14 hours at room temperature.
The longer you let it steep the stronger the cold brew will be.
Once the mixture has rested you need to filter out the ground coffee using a cheesecloth or a coffee filter.
Next, you need to taste your cold brew if you find that it’s too strong, dilute it with some water
Now once your cold brew is to your liking, you need to place your coffee into the fridge until it is chilled
Once your cold brew has chilled pour your cold brew coffee into your whip cream maker
Next, screw on your charger to release the Nitrogen gas
And then vigorously shake your whip cream dispenser up to allow the nitrogen gas to diffuse throughout the coffee
I would advise letting the dispenser rest in the fridge for 15 minutes to allow the gas to dissolve completely into the cold brew coffee,
some people leave it to rest for a lot longer even overnight
Finally, you can proceed to pour out your nitro coffee into a glass cheers.
