It's a refreshing drink when served cold. A bit sweet when warm. A little tart, but tolerably so.  The flavor is less orange than tangerine, yet I can distinguish several different "layers" of citrus in it, including the orange. It's an interesting sensation.  I am a little bugged by the fact that an 8.3oz can (2/3rd-size) manages to pack more junk calories in than a full-sized can of cola. It's also supposed to be 100% juice, but reconstituted grape juice is practically pure sugar and there are "natural flavors" noted in the ingredients list as well as a soy warning which to me implies some sort of MSG, probably added with the citric acid.  So, maybe it's not an especially healthy beverage. It's still tasty and provides a diversion from more typical sodas.

The freshness is great during the initial crunch but once the chewing and swallowing takes place, these pretzels are very earthy and grainey tasting...I have several bags you can have for free.
