Nitro cold brew coffee. It's kind of all the rage. And why not? It has the same fundamental characteristic of cold coffee, in that it's cold. (Some make it with cold brew, giving that mellow, low-acidity flavour profile that is also trending, but some make it with chilled hot-brewed coffee.) And on top of that, it has a great texture ('guinness like', or for non-drinkers, creamy and warm), and looks stunning.
Nitro's great. I'm a fan. The main problem: it's expensive - I've seen it go for anywhere up to US$10 a glass. That is OK for the occasional indulgence, but there's no reason you can't make it for yourself at home and indulge as often as you like. Because there are...
Three dirty secrets about nitro cold brew
Dirty secret #1: You can make the base of nitro (cold brew) in a bucket.
Or a jar, if you're at home making non-commercial quantities. Cold brew can be made in many ways - you can make hot coffee and chill it, you can slowly drip water over coffee grounds over 8+ hours, or you can just immerse coffee in water and store it somewhere safe. I make hot brew (using a very standard method like using a pour-over device or an Aeropress) and chill it, so I don't have to adjust my grinder.
Dirty secret #2: Nitro coffee is basically cold coffee with air mixed in.
Nitro is essentially cold coffee with nitrogen dissolved in it, and air (the stuff you're breathing... unless you're a web-crawling robot) is about 80% nitrogen. The reason they don't use air in making kegged nitro is because of the oxygen component of air, which, if I may oversimplify, makes coffee go bad much more quickly.
Dirty secret #3: You can make nitro coffee with a blender.
Yeah ok so it's 'nitro-esque'. But it's basically the same texture. You just dissolve air into coffee with a blender. And get pretty much the same effect.
