Food & Wine:

Officially announced today, but still very much in a prototype phase, the Signature’ version of the drink (there’s a Vanilla flavor, too) uses essentially the same recipe as traditional Pepsi, but ditches the crisp, palate biting bubbles of carbonation for smoother nitrogen which is already a mainstay of high-end, on-tap cold brew and dark, stout-y beers. Like a freshly-poured Guinness, Nitro Pepsi’s micro-bubbles cascade downward and the a frothy head forms at the top of the glass, remaining there much longer than that familiar fizzle of fountain sodas.

I’d be willing to try one.
