I'm usually a sucker for seasonal flavors and limited edition products, but I wasn't too interested in these when I first learned about them. Some combination of the thin hipster can, the boring packaging artwork and the fact that it's Diet Coke (I'll always be Team Pepsi) caused this to fall completely off of my radar. However, these were on sale so it's time ti give 'em a shot.
The flavors really aren't all that different from one another. They're Diet Coke with a mild spicy aftertaste and a slight fruit flavor. They're not bad, but they're nothing special. If your local grocery store charges the same for this as they do for regular Diet Coke, give it a shot, but it's not worth paying extra.
