The secret to a stable society? A steady supply of beer doesn't hurt

Scientists analyzed bits of beer vessels from an ancient Peruvian brewery to learn what the beer was made of and where the materials to make the vessels came from. They learned that production was local and that the ingredients for the beer included pepper berries that would grow even in droughts. The authors argue that this steady, reliable access to beer helped maintain unity in the empire.
