They didn’t invent Nitro coffee, but Slingshot Nitro Flash Brew is proof that they perfected it. First it's coffee is brewed hot (yep, you read that right) then they flash chill it right away to lock in its sweet aroma and tasting notes of caramel, baking spices, and dark fruit. Finally, it's infuse it with nitrogen to get that creamy texture and frothy head we know and love in Nitro coffee.
