Native to the Midwestern United States and little known elsewhere, Blue Moon’s flavor dances on the tip of your tongue, taunting you into another guess, at turns familiar and elusive. It’s bright, mildly citrusy, and almost fruity, but not in a cloying way. It’s the aftertaste in particular that is, frankly, somewhat infuriating, a flavor layer that seems to say, “you know what this is,” but you don’t—and in fact, very few people do.
