There's a Hemp trend on this shelf. Hemp, the original, is in the yellow and green cans on top. The black ones are Hemp Black Label, and the bottles are Hemp Gold. I don't recall actually getting around to trying these ones, and I imagine if they're still sealed in my garage that they probably taste like acrid crud by now. Perhaps they mellow with age. (Also, perhaps they don't.)
Yellow V, lemon flavour, was a temporary addition to the V lineup that I actually rather liked. Mother, on the other hand, has always had a reputation for tasting largely like shite, even though the new formulation seems to just be another Red Bull/Monster Energy clone in a gigantic can. At least it doesn't taste like the old formula.
