Nitro cold brew is a variation of cold brew coffee that uses
the addition of nitrogen gas to create a smooth texture, delivering the nitrogenated coffee from a nitrogen beer tap system. It was introduced in the early 2010s.
Production of nitro cold brew coffee begins with the making of cold brew coffee. Once the grounds are adequately steeped, the coffee is poured into a room-temperature bottle or keg. As the cold brew is poured into a cup, it is charged with nitrogen to give it a rich, creamy head of foam, similar to draft beer. Nitro cold brew is typically served chilled but without ice, which would damage the foamy top.
