On this day 500 years ago, an obscure Saxon monk launched a protest movement against the Catholic Church that would transform Europe. Martin Luther’s Protestant Reformation changed not just the way Europeans lived, fought, worshipped, worked and created art but also how they ate and drank. For among the things it impacted was a drink beloved throughout the world and especially in Luther’s native Germany: beer.
The change in beer production was wrought by the pale green conical flower of a wildly prolific plant — hops.
In one – and rather archaic – meaning, beer is with hops, ale is without hops. Thus the addition of hops doesn’t change beer it creates it.
