The flavor is nothing but a maddeningly bland Red Bull clone, albeit with misguided idiosyncrasies that only give the experience a rushed and awkward feel. First off is the sourness; initially non-existent with a touch of medicinal bitterness instead. Things do eventually become tart as ounces are coerced, but it is a chemical creation unfun to the tongue. A less acute acidity would averagely be applauded, however such an austere abatement leaves a flavor uncharacteristically apathetic. Speaking of flavors, there is only vanilla honestly present, with perhaps some diluted citrus for purposed complexity. This leads us to the next problem outside the obvious one-dimensional taste; the vanilla itself. It is slightly alcoholic which tastes about as good as it sounds. The assumed cause is the beverage's tripe sweetness, woefully weak and also conceivably the cause for the aforementioned adulterated acerbity. Overall, XS Classic Blast is anything but what the name suggests.
Caffeine (124.5mg), B vitamins, ginseng, taurine, and its special herb blend are the ingredients to mention, an energy cocktail obviously made by a noob bartender. The buzz lasted something under two hours, unfortunately typical for the line. In the end, XS Classic Blast may be bad, but it at least takes a risk or two.
