Ancient Chinese pottery reveals 5,000-year-old beer brew

Residue on pottery from an archeological site has revealed the earliest evidence of beer brewing in China left from a 5,000-year-old recipe, researchers said Monday. The artifacts show that people of the era had already mastered an "advanced beer brewing technique" that contained elements from East and West, according to a study in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal.
