Sour cherry smell out of the pkg, adds light floral scent when steeping. Immediately turns pink, then darkens to deep pinkish purple (magenta?) as it brews. Looks like a hibiscus tea would.
Taste is tart up front, then fuzzy. I don’t know how else to describe it, not knowing what acerola or elder flower taste like on their own. I don’t particularly care for the puckery/fuzzy combination of mouthfeels. I do suspect this may be good iced since there is a bit a juiciness under the tart lemon and sour cherry.
Acerola is a sour tropical cherry that is high in vitamin C, read about it here: http://en.wikipedia.org/wiki/Malpighia_emarginata
