Example Input: One of my favorite but rare indulgences is a can of orange soda; so I was looking forward to the combination of bubbles and orange flavor when I popped open my can of Switch Orange Tangerine. To my disappointment, it tasted more like fruit punch, perhaps because of the apple and grape juices in it to sweeten it. I would say the makers of this drink went overboard on the apple-grape combo, not just in the flavor department, but in the sweetness. It's sticky icky sweet, more than any of the cheaper brands (Sunkist, Crush and others) of orange soda, or the higher priced goodies like Orangina and the delectable Izze.  It is fairly healthy however, with no bad stuff and quite a lot of Vitamin C (100% based on 2,000 calorie intake), All Natural, etc. My recommendation is for more orange, less apple/grape, or change the label flavor to "mixed fruit." It's 140 calories per cute little 8.3 oz can, and if you're not expecting orange you may like it. So far, the taste winner for cute little cans for me is Izze's Grapefruit, which has the perfect balance of flavor and carbonation, with the right amount of sweetness.
