Nitro coffee

Nitro is cold brew infused with nitrogen and served on tap — it looks and behaves a lot like a dark stout beer. When poured, you get a cascading swirl of tiny bubbles and a creamy foam on top. Nitrogen creates a very different texture from regular carbonation: the drink feels smooth and velvety, with none of the sharp fizz you'd get from CO₂. It's usually served without sugar or milk, because the whole point is that rich, creamy, almost dessert-like mouthfeel. In specialty cafés, it's a way to offer something on the cold menu that you simply can't replicate at home.
