This past Thursday, Pomegranate 7 Up was produced in limited run for the Holiday season. It should show up in stores anytime as long as the run passes the final lab runs after it's standard 3 day hold period.
If you like POM brand products and you like Cherry 7 Up you should like this.
If you don't like Pomegranate then don't even bother.
No plans for a diet version to be produced yet.
