Archaeologists have unearthed a bronze kettle containing liquor from a Qin Dynasty tomb, dating back more than 2,000 years in West China's Shaanxi province.

The kettle is a sacrificial vessel. It was among among 260 items unearthed from a graveyard of commoners' tombs from the Qin Dynasty (221-207 BC). Most of the relics were for worshiping rituals.

Xu Weihong, a researcher with the provincial archeological institute, said about 300 ml of liquor was found in the kettle, which had its opening sealed with natural fibers.

The liquor is a transparent milky white. Researchers believed it was made using fermentation techniques, as it was composed of glutamic acid substances.
