What “Green Thunder” actually means is beyond me, and it is most curious that this Mio variety gets a creative name, where as the other only has a generic “Black Cherry” moniker. And while the red of the latter was a bit better to the eye than so is this marriage of the blue and yellow primaries, the green really pops off of the black regardless of my preference.
Two squirts and the clear, two cup glass of water is now died bright green, though it remains translucent as ever. The resulting flavour is incredibly weak, though, tasting something of a diluted citrus, naming no specific fruits or displaying any secondary characteristics. But four fun squeezes is when the beverage begins to form into its own, with a sharp pierce of sourness cutting into the still unspecified fruit blend. Lemon and lime are probably involved, perhaps some pineapple added in for complexity matters, and who knows, there is likely a pinch of guava to each sip, but never expect anything to find its feet and stand up out of the crowd. Few ounces remain and your throat is thick with this syrupy solution, one that is comparably sweet to Mtn. Dew, albeit all synthetic sugars, but this self service concentrate is as good, though personally better, tasting than the Black Cherry variety.
I ultimately utilized four splashes, yielding a caffeine content of about 240mg, with some taurine, ginseng, guarana, and B vitamins thrown in for good measure. The kick will vary, obviously, but mine was four and a half hours, with no jitters to boot. Overall, Mio Green Thunder is the little line's best simply because of its taste.
