Just the right kind of light sweetness with out syrupyness not possible with corn syrup (HFCS). I just don't care a whole lot for this flavor. It makes a good mixer.
This is by far my fovorite sparkling juice. The blueberry flavor is just perfect in the way as its just strong enough so it doesnt make you hate it. But the bite is very strong, which I find one of the best parts of a sparkling/carbonated beverage.
