Cold Brew Coffee & Nitro Coffee Equipment
What Is Cold Brew Coffee and Why Use Nitro?
Well it's exactly what it sounds like. Normally hot water is used to extract the flavour from ground coffee beans quickly. Cold brewed coffee uses cold water to gently extract the coffee from the grounds over a much longer period of time (12 hours usually instead of a minute or so for hot extracted coffee).
This results in a mild smooth flavour compared to espresso or filter coffee but also a high caffeine level. Cold brew coffee is still full of flavour but with much less bitterness so it is often served black on ice.
If a creamy mouthfeel or texture is desired the cold brew can be infused with nitrogen gas and then pushed through small holes under pressure. Doing this essentially "whips" the coffee and it pours creamy and white with a dense foam on top like a cappuccino without using any form of milk, dairy or otherwise. Pouring using Nitro also creates attractive cascading bubbles that are visible if served in a glass (it looks similar to a Guinness stout beer!).

Stout Dispensing
Guinness or other already nitro-infused cans or bottles: simply pour these into our keg and dispense with CO2 or N2O through a stout spout. If using a regulator and CO2: you will need a higher than normal pressure to push it through the spout so remember to turn it down and release some pressure before leaving it to sit or you will over-carbonate the beer. If using our nitro spear: You can just inject a bulb of N2O and pour, be aware that leaving the stout in the keg with high-pressure N2O will affect the texture if left too long. It is better just to put what you will drink in one session into the keg when filling from cans or bottles.
Non-nitro infused cans or bottles of stout / porter (and carbonated homebrew): If you want to get nitro style stout you need the nitro injector spear. Pour the beer into the keg and then inject a couple of nitro bulbs, let sit for a couple of hours or gently swirl /rock the keg for 10-15 mins to absorb the nitro into the beer. After that pour using the description above for nitro-infused beer.
