Chinese researchers have confirmed that liquid found inside a bronze vessel more than 2,000 years old was an ancient grain wine. The pot was discovered in a Warring States Period tomb in Ningxia, north-west China. Despite lacking a conventional lid, it had been sealed with fabric and mud, preserving around 3.7 litres of liquid.
Using advanced chemical and microfossil analysis, researchers identified thousands of compounds as well as starch grains, yeast and plant remains. The results showed the liquid was a fermented grain drink made using cereals including barley and wheat.
The find offers rare physical evidence of ancient Chinese brewing methods and provides new insights into agriculture, diet and craftsmanship before the Qin Dynasty. It also shows how modern technology is transforming archaeology, allowing scientists to uncover details about ancient objects that would once have remained hidden.
