In a discovery that rewrites ancient history, archaeologists have uncovered what may be China’s oldest distilled liquor, hidden in a bronze owl-shaped vessel from the Shang Dynasty. This groundbreaking find, dating back over 3,000 years, challenges the timeline of distillation technology in China, revealing that the practice was used long before previously thought. The discovery not only sheds light on ancient Chinese craftsmanship but also opens a window into the ceremonial practices of one of China’s earliest dynasties.
The Discovery of the Owl Vessel
The journey to uncover this extraordinary artifact began in December 2010, when archaeologists from the Jinan Institute of Archaeology unearthed the bronze owl-shaped vessel at the Daxinzhuang site in Jinan, located in Shandong Province. The vessel was discovered in Tomb M257, a burial site believed to belong to a member of the Shang Dynasty elite. This period, known for its advances in metallurgy and craftsmanship, provides a rich backdrop to the discovery.
The bronze vessel, standing out for its intricate owl design, was in remarkable condition. Very few owl-shaped vessels of such quality have been discovered in Shandong, making this find especially significant. The craftsmanship suggested it was not only a functional object but also a symbol of status or a ceremonial item. Its importance was immediately apparent to the archaeologists, and it was carefully excavated for further analysis.
Upon initial inspection, the vessel was found to still contain a small amount of liquid. However, because the lid and body were corroded together over the centuries, archaeologists could not immediately open the vessel to examine the contents. The sealed nature of the vessel led experts to speculate that it could contain a funerary offering, likely a liquid used in burial rites, but the exact nature of the liquid remained a mystery until much later.

Initial Analysis and Preservation
After the excavation, the vessel was placed under the care of the Shandong Provincial Department of Culture and Tourism. With the conservation of all artifacts recovered from the Daxinzhuang excavation, the preservation and protection of this bronze vessel became a priority. In late 2024, the department approved a plan to carefully conserve the vessel, allowing for the eventual opening and analysis of its contents.
One of the challenges faced by the conservation team was the corrosion that had fused the lid and body of the vessel. Working meticulously, experts from the Shandong Provincial Cultural Relics Protection, Restoration, and Identification Center were able to treat the corrosion at the contact point, carefully opening the vessel without causing further damage. Inside, the vessel contained a clear, colorless fluid that appeared to be a form of alcohol, likely a wine used in funerary rituals.
Scientific Testing of the Liquor
With the vessel successfully opened, a sample of the liquid was sent to the archaeology laboratory at Shandong University for detailed testing. The researchers employed cutting-edge technology, including solid-phase microextraction-gas chromatography/mass spectrometry (SPME-GC/MS), to analyze the volatile organic molecules in the sample. The results of this analysis were groundbreaking.
The sample was found to contain water, ethanol, ethyl acetate, and other byproducts of distillation. These findings were significant because they confirmed that the liquid was distilled liquor, a process that involves the separation of alcohol from other liquids by heating and condensation. This was a key discovery, as it showed that the ancient Chinese had developed distillation techniques over a thousand years earlier than previously believed.
The analysis also revealed that the sample did not contain the sugars, proteins, or organic acids typically found in fermented beverages like fruit wine or rice wine. These substances, which are present in fermented drinks, can cause the liquid to turn acidic and dissolve copper corrosion materials, giving the liquid a blue hue. In contrast, distilled liquor remains colorless, with a neutral pH. The pH of the liquor in the owl vessel was found to be 5.8, just shy of neutral, further supporting its identification as distilled alcohol.
The Historical Context of Distillation
This discovery pushes the timeline of distillation technology in China back by over a thousand years. Prior to this, the oldest known evidence of distillation in China came from tombs dating to the Han Dynasty (202 B.C. – 220 A.D.), much later than the Shang Dynasty. Distillation had already been practiced in ancient Egypt, with the earliest records of distillation in the Mediterranean dating to around 3000 B.C. The discovery of distilled liquor in a Shang Dynasty tomb, however, suggests that the technology was independently developed in China, around the same time it emerged in Egypt.
Historically, alcohol made through fermentation, using fruits and rice, has been found in China as early as the Neolithic period (around 9,000 years ago). Written records from the Zhou Dynasty (1046 B.C.–256 B.C.) even describe the production of alcoholic beverages through fermentation. However, this new find demonstrates that the Chinese were already experimenting with more advanced methods of alcohol production, such as distillation, during the Shang Dynasty, a revelation that could change our understanding of ancient Chinese technology and social practices.
Significance of the Find
The discovery of distilled liquor in the Shang Dynasty bronze vessel not only rewrites the history of distillation in China but also sheds light on the sophistication of the Shang people. The ability to distill alcohol was not a simple craft; it required advanced knowledge of chemistry and the use of tools capable of precise temperature control. This discovery indicates that the Shang Dynasty was far more technologically advanced than previously thought, with a deep understanding of processes that would later play a significant role in the development of Chinese medicine, alchemy, and even the production of spirits.
Furthermore, the presence of the distilled liquor as a funerary offering provides insight into the spiritual and ritualistic practices of the time. Alcohol was often used in ancient cultures as a form of tribute to the deceased, thought to provide sustenance or facilitate communication with the afterlife. The discovery of such a drink in a royal tomb suggests that the Shang rulers were using the technology not only for practical purposes but also as part of elaborate burial ceremonies.

Conclusion
The discovery of distilled liquor in a bronze owl vessel from the Shang Dynasty represents a monumental breakthrough in Chinese archaeology. It not only extends the history of distillation technology by 1,000 years but also provides new insights into the technological and cultural advancements of the Shang people. As research continues at the Daxinzhuang site, more discoveries may emerge, further enriching our understanding of this fascinating ancient civilization. This find serves as a testament to the ingenuity of the ancient Chinese and their ability to master complex techniques long before the world knew of them.
