Espresso Martini in a can has the same rich, velvety-smooth texture classic of the freshly prepared classic. In terms of the crema that makes the Espresso Martini what it is, the Kahlúa Espresso Martini can is designed with first-of-its-kind packaging fitted with a smart nitrogen widget that forces bubbles to the surface upon opening to create a smooth, creamy layer. To best enjoy, all you have to do is pop the top, pour into a martini glass, and allow 20 seconds for the crema to set.
