The phrase "herbal carbonated drink" makes us think of fizzy dirt tea, so when we saw it on the label for Rejuvenizer, we were reluctant to try it. The fact that the green tea/cranberry flavored Rejuvenizer is a dark purple color didn't help (we have a history of falling down with purple drinks). But we finally forced ourselves to take a sip, and surprisingly, it wasn't horrible.
There are fruity overtones to Rejuvenizer because it contains cranberry juice concentrate, but the dominant taste is a strange, earthy funk, thanks to the bizarre blend of herbs. Some of the ingredients, like dandelion root, green tea extract, and ginseng, and common in herbal teas. But some others -- like shiitake and reishi mushrooms, and kombucha (a tea fermented from a fat ball of yeast and bacteria) -- add a dash of dirty feet flavor, which is a dash too much.
