About 45% of consumers said they are interested in trying nitro cold-brew coffee after reading a description of what it is, according to Technomic’s Fall 2018 Convenience Store Consumer MarketBrief. To make nitro coffee, nitrogen gas is pumped into brewed coffee, resulting in a smooth and creamy mouth feel that is reminiscent in appearance and texture of a Guinness beer. Nitro cold brew is one of the many coffee varieties offered at Alltown Fresh, and it is quickly becoming a hit among customers, according to the company.
