Dr. Pepper Dark Berry

Dr. Pepper Dark Berry is what you get when Dr. Pepper needs to grab some press. Some folks I've met love this stuff. To me it just tastes like Dr. Pepper. 

It's blue so that could mean blueberry which tastes like nothing anyway. Then again, the fact that they don't tell you what kind of berry is worrying.  

On the other hand, if you drink Dr. Pepper then you have no idea what it should taste like and so not knowing should be just fine. We drink the good old pepper for the caffeine.
