Beer is the perfect accompaniment to pizza, a refreshing punctuation mark at the end of a day. But a growing number of academics see it as something more — a substance that can tell us important things about the world.
In many ways, brewing and human society grew hand in hand. Beer was the choice of generations long past — in China, people were drinking beer as long ago as 7000 BC — and today is the most-consumed alcoholic beverage globally.
Historically speaking, beer and the business of brewing have shaped everything from trade to national tastes. In Germany, for instance, the Reinheitsgebot (“purity law”) — a regulation on the books for nearly 500 years — dictated beer could be made of barley, hops, water, and nothing more. (The law is so old it predated the use of yeast.) It was repealed in 1987 when the European Court of Justice determined it interfered with trade in Europe. But over time, says Belgian economist Johan F. M. Swinnen, “German consumer preference adjusted to it to such an extent” that it still defines the tastes of one of the great beer-drinking nations.
