I ttried some diet pomegrane 7-up tonight. It's pretty tasty. It think the pomegrante flavor is rather mild; not too overwhelming. The label indicates it's a limited edition. I suspect this means the holidays, so it may not be around after that. Just thought I'd pass along the info...
If you are looking for a nonseasonal Pomegranate soda then I have to recommend my favorite soda. It is called Pomegranate Dry and made by Polar Beverages. Also the Orange Dry is great. It is distributed in the Northeast and now that I moved to MN, I really miss it.
