Rockstar Iced Peach went for a sugarless candied taste instead of realism, a fault that corrupts all of any potential the flavour had. It is not a particularly bad flavour; you can certainly take each sip with little trouble, but the experience pales in comparison to drinks like the wonderful Go Girl Peach Tea. The fruit flavour is alone on the tongue, and it demonstrates neither an understanding of its natural potency or complexity. Rather, each sip flounders with stupefying jejuneness and overall decrepitude, and each of many unimpassioned sips drink with with zero satisfaction. It is sweetened with sucralose and ace-k(or "acesulfame, comma, potassium," as the can erroneously reads), however the duo is unable, though not incapable, at properly honeying the flavour, with a noticeable artificiality present during and following each gulp, an unnaturalness that rivals that of the actual taste in terms of severity and unpleasantness. Overall, I always try to make it obvious when I do and do not like a drink, and where this one rests should be obvious.
Each can contains an impressive 240 milligrams of caffeine, some taurine, B vitamins, ginseng, inositol, and guarana. The kick extended just beyond four hours and was of decent strength, and it ended with no crash. In the end, Rockstar Iced Peach Tea succeeds in all areas except where it truly matters: taste, because it does not matter how strong your drink is if one must suffer sixteen ounces to get there.
