It's, um, turquoise. I was not expecting turquoise. I've had this stuff before, and all I can recall is that it tasted pretty horrible, so seeing it outside the can was something of a surprise. Recharge by Sprite bottles are coated, head-to-toe, in opaque labels, so even the glass containers provide no hint as to the blue-ness hiding inside. It remains carbonated for a great length of time, also.
Also worth noting is that the Recharge by Sprite cans are exorbitantly lengthy, containing an extra inch of aquamarine goodness. I postulate that a further inch is required to provide the same amount of fluid as in a regular shaped can.
It does not have a strong odour. It vaguely stinks of medicine and vitamins, which is odd as it does not seem to contain the usual myriad vitamins these drinks boast.
It tastes quite medicinal. There's a good portion of earthy vitamin flavours hiding behind it, and there's a zing of something slightly anaesthetic, possibly mint.
The anaesthetic taste/sensation continues, leaving an aftertaste of nothing but medication. I have a suspicion someone switched the vats of genuine Recharge by Sprite with Listerine while the Coca Cola folk weren't looking, because quite frankly, it tastes like mouthwash.
It's blue, tastes like mouthwash and remains fizzy for great lengths of time. Other than that, it's pretty morbid stuff.
