I used the small cup setting and even opened up the cap and scraped the excess mix out of the cup and it is still very weak tasting.

Ex Input:
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 kids love the hot cocoa and I like the fact that I can get the stuff shipped to me when I need it without worry of order.
