XI’AN, China, Aug. 11 (World Daily Times) — A sealed bronze vessel from a tomb in northwestern China contained about 3,740 milliliters of liquid — nearly a gallon — that researchers say is consistent with a fermented, non-distilled alcoholic drink made from grains.
The finding comes from a study published in the Journal of Archaeological Science: Reports. The analysis examined material from one vessel recovered from Tomb M39 at the Shanjiabao cemetery in Ningxia. Because the evidence comes from a single vessel, the study offers a detailed case study rather than a broad measure of how people across ancient China made alcohol.
The supplied publication record does not establish whether the paper’s peer-review process was complete. It also does not provide information about independent replication, statistical analysis or confidence intervals.
What was found?
The liquid was recovered from a bronze vessel with a garlic-shaped mouth. Researchers described it as clear and light blue-green, with a small amount of sediment and no noticeable odor when it was examined.
The vessel had been sealed with more than one layer. According to Wang Xiaoyang, who led the Shanjiabao excavation project, fabric was placed inside the mouth and organic-tempered clay or daub was applied outside. The study attributed the liquid’s preservation to the seal, which helped limit evaporation and contamination. Researchers also pointed to the area’s relatively dry conditions and the burial environment as possible factors.
The cemetery contained 183 tombs, according to accounts of the excavation. Tomb M39 has been associated with the Qin and Warring States period, broadly dated in the supplied accounts to 475 to 221 B.C. That range is why reports have described the liquid as roughly 2,200 to 2,300 years old. The exact age depends on the dating used for the tomb and vessel.
Why researchers call it a fermented drink
Analyses found evidence from organic chemistry and microscopy, including organic acids, starch grains, plant structures known as phytoliths and yeast remains. Taken together, the reported evidence is consistent with a fermented cereal-based beverage.
The researchers identified broomcorn millet as the main grain. They also found grains from the Triticeae group, which includes wheat and barley. Some reports say more than 92% of the starch came from millet, but the supplied accounts do not present that figure consistently.
“Beer” is a convenient media label for the discovery, but it may not be the study’s formal classification. The evidence supports a fermented, non-distilled drink. It does not establish that the liquid was identical to modern beer, nor does the supplied research establish its alcohol content, flavor or exact recipe.
Ruru Chen, identified in coverage as a researcher involved in the study, said the drink would not have been a distilled spirit. Distillation produces a much stronger alcohol by separating and concentrating alcohol from a fermented liquid. The reported evidence instead points to a drink that remained in its fermented form.
How strong is the evidence?
The result is notable for the amount of liquid that survived and for the number of different types of evidence used to identify it. The vessel preserved a large sample in a sealed container, and the researchers used chemical and microscopic clues rather than relying only on the vessel’s shape or its location in a tomb.
But the study’s scope is limited. The reported analysis concerns one vessel from one tomb. The available information does not include a full account of the laboratory methods, contamination controls, uncertainty estimates or independent tests by another research team. It also does not show whether similar liquids were recovered from other tombs at the cemetery.
That means the finding supports conclusions about this particular liquid and the people who made or deposited it. It cannot, on its own, show how common this brewing method was throughout the Qin cultural sphere or establish a general pattern for ancient Chinese alcohol production.
What the tomb context may mean
The vessel’s location inside a tomb provides evidence about burial practices, but it does not prove why the liquid was placed there. Some accounts have suggested it may have been a burial offering. That interpretation remains unconfirmed in the supplied material.
The discovery does, however, preserve a physical link between grain use, fermentation and burial customs in the region. Chen Luru said the study shows how people of the Qin era used grains and what brewing technologies they employed.
The result is therefore less a claim that an ancient bottle of “beer” has been found in exactly the modern sense than a carefully documented example of a cereal-based alcoholic drink surviving under unusual archaeological conditions. Further excavation, clearer publication of the study’s methods and independent analyses would be needed to determine how representative it is of brewing in ancient China.
