Coffee’s next iteration, nitro coffee—a cold brew that’s been injected with nitrogen, improving the mouthfeel and drinkability of cold coffee—is being incorporated into alcoholic and non-alcoholic coffee drinks. Nitro tap systems are available for restaurants and coffee shops. Lettuce Entertain You’s Beatrix’s coffee bar serves up Caramel Cream Nitro, made with cold brew nitro, house-made caramel, whipped cream and sugar.
