This is marketed to the Mexican market, in the Mexican section of grocery stores, and with half Spanish labels. The ingredients are just hibiscus, sugar, and water. I'm sure there must be color added. The flavor is a bit like tea, maybe a light green tea, and the sweet red juice suggests grape juice. All in all this is pretty sick tasting, and I wouldn't try this again. Props from being from UNC, though.
Liked this product. Can't find it anywhere. Not too sweet, would be pefect accept for the "cooked" taste from the pasteurization, kept belching up that "cooked" taste.
