Sure: the popularization of coffee across western Europe in the 1600s and 1700s, and the way it replaced beer as the most common daytime casual drink. Much of the population went from spending all day mildly intoxicated to being mostly sober and with a caffeine pick-me-up.
Do you know if it was really most the population? Or just most of the intellectuals, nobility, bourgeois, etc. Were peasants coffee drinkers?
