"Panaché" is the beverage, which is a shandy-type mix of beer or ale and limonade or perhaps Ginger-Ale. Alcohol content is 1.3%. Drinking age in France is 16.
Will Wilkinson wants to scrap all drinking age restrictions:
UCLA professor of public policy Mark Kleiman, an ex-advocate of age restrictions, told PBS that he came around to the no-limits position when he saw a billboard that said, "If you're not 21, it's not Miller Time--yet." Age limits make drinking a badge of adulthood and build in the minds of teens a romantic sense of the transgressive danger of alcohol. That's what so often leads to the abuse of alcohol as a ritual of release from the authority of parents.
