In northeastern Poland, researchers found evidence of alcoholic beverages fermented over 4,500 years ago. The discovery was made in vessels belonging to the Bell Beaker culture, according to a study led by Dariusz Manasterski from the University of Warsaw.
The analysis of 13 containers found at various archaeological sites revealed that at least nine contained metabolic products from bacteria and yeasts, confirming that fermentation took place. These remains represent one of the oldest indications of alcoholic beverage production in the region.
Scientists detected biomarkers related to the processing of wheat and barley, fruits, and possible resins that could have been used to preserve or flavor the beverages. Some vessels may have contained more complex mixtures, similar to the known Nordic "grog."
Details of the Archaeological Study
Manasterski explained that the grain used in the production was likely imported from areas where cereal cultivation was already well established. This suggests networks of exchange and advanced technological knowledge for the time.

The discovery provides new information about fermentation practices in the early Bronze Age in central and northern Europe. Alcoholic beverages likely played social, ritual, or even medicinal roles in the communities of the Bell Beaker culture.
Researchers used advanced techniques to identify the organic residues preserved within the vessels. This type of analysis allows for the reconstruction not only of the ingredients but also of the beverage preparation processes from millennia ago.
The study, published in the journal Archaeometry, highlights the importance of fermentation in European prehistory. The evidence indicates that the production of alcoholic beverages was more sophisticated than previously thought for that period.
Historical Context of Fermentation
The Bell Beaker culture is characterized by its distinctive ceramics and spread across much of Europe during the third millennium BC. In this context, fermented beverages may have been part of banquets, ceremonies, or social exchanges.
This finding adds to other archaeological evidence showing the early use of alcoholic beverages in different parts of the world. In Poland, preservation conditions allowed organic residues to survive to this day.
Experts continue to analyze the data to more accurately determine the recipes and possible uses of these beverages. The research opens doors to better understand the daily and ritual customs of these ancient populations.
From Science in Poland, the relevance of the work by the University of Warsaw team was highlighted, combining field archaeology with cutting-edge chemical analysis. These discoveries enrich the understanding of technological and cultural innovations from 4,500 years ago.
