For a drink that uses sugar alternatives, I think Swoon's lemonade drinks are undoubtedly better compared with other canned drinks that are zero-sugar. You probably will still get that artificial sweetener aftertaste but it's not as pronounced as some other brands. I probably still prefer sparkling waters but if I'm craving something sweet and don't want the calories, this is a decent option.
Fruity flavors definitely lend themselves well to the sweetener blend for Swoon! Would love to see more canned drink flavors.
