Cold brew coffee is joined by nitrogen gas in a refrigerated tank. It is completely sugar and dairy free and has less-acidic flavors. At Starbucks, a grand (large, 16 fl. oz.) nitro will range in price from $3.25 to $3.95, depending on the market. Nitro is significantly different. It is one of the hottest trends in coffee today! To make a nitro coffee at home the following are needed: coarse ground coffee, filter paper, whipped cream dispenser + n2o cartridge, jar with cover, water pitcher and mixing spoon. In addition to launching nitro coffee, Starbucks is unveiling a new drink: Vanilla Sweet Cream Cold Brew is cold brew coffee served on ice and topped with a float of house-made vanilla sweet cream, made from milk, cream, and vanilla-flavored syrup.
