Archeologists have been researching how an ancient Peruvian empire was so successful that it lasted for centuries — and it turns out the answer is… beer.
With his team at the Field Museum in Chicago, curator Ryan Williams discovered a site at Cerro Baúl in the mountains of southern Peru that once served as a kind of microbrewery for the Wari civilization. Predecessors to the Incas, the Wari flourished from roughly 600 AD to 1,000.
