That may look like a dark beer, but it's not, it's nitrogenated coffee In recent weeks Colectivo Coffee Roasters has introduced a new beverage poured at their beer bars: Nitro Cold Brew Coffee .Wait what? Are you confused? I was at first and had to ask. What is this? Is it a new coffee beer (they already have a coffee stout)? Is it a coffee? Well, first, though it is served from a tapper alongside their beers (at locations that have them) it is not beer. It is coffee. Just coffee. OK, not just coffee. No, really it is. The name actually says exactly what it is: nitrogen infused cold brewed coffee. That is all. It is essentially carbonated (nee nitrogenated) coffee. But the end result is very unique ending up looking and drinking like a light stout except without the alcohol. And that's a good thing, a very good thing. You can read Colectivo's release information here , but I'll continue with my own description and review.
