To the yang of every superhero’s rise, there is the yin of an equally formidable foe. Batman and the Joker, Spiderman and the Green Goblin, and in the fermented dairy aisle, Greek yogurt and acid whey.

It is not hard to imagine a consumer reaching past a bloated yogurt package with a look of disgust. Now imagine him or her reaching past that yeast-spoiled cup for a pristine package of the adjacent yogurt brand, turning it over and then exclaiming, in equal disgust, "Sorbate, I’m not eating that!" The yogurt goes back on the shelf, and the consumer walks away from the cultured dairy aisle.
