I first tasted Nitro Cold Brew (NCB) on a coffee crawl through New York’s East Village with a friend of mine as my guide. That friend also happened to be a lead barista at Third Rail Coffee, a popular indie coffee shop in New York City’s Greenwich Village. I had my first taste of NCB at one of ours stops and I was utterly confused and captivated. I immediately explained to my friend that this was like no coffee I’d ever had. Instead, with its thick mouthfeel and foamy (yet creamy) head, it tasted similar to Guinness…yes, the beer. It took a few years, but NCB has really started to become a trend in indie coffee shops throughout the main island of Oahu. Let’s sample some of the options, but do keep in mind that they were all ordered black (as coffee should be).
