4,500-Year-Old Pots in Poland Hold the Region's Oldest Trace of Beer

Level 3 — Intermediate

A team from the University of Warsaw and Lodz University of Technology has identified the oldest chemical traces of beer-like alcoholic drinks ever found in northeastern Poland. The researchers analyzed shards from broken pottery linked to funerary and ritual features at the sites of Supraśl in the Northern Podlasie Lowland and Skrzeszew in the Mazovian Lowland. Their study appears in the journal Archaeometry.

The vessels belong primarily to the Bell Beaker phenomenon, one of prehistoric Europe's most distinctive archaeological horizons. The culture spread across much of the continent in the second half of the third millennium BCE and is named for the elegant bell-shaped pots its makers produced.

Using organic residue analysis, the scientists detected molecular markers consistent with fermented cereal-based drinks. Some samples align with a beer-like beverage, while others suggest a more complex mixed-fermentation drink sometimes described as Nordic grog. The chemistry indicates that brewing knowledge was already established in this borderland between northern and eastern Europe.

Researchers caution that residues alone cannot tell us exactly who drank what, or in what amounts. But the contexts—graves, communal pits, ceremonial areas—suggest that the beverages played a role in negotiations among the living and rituals for the dead, much as alcohol does in many later cultures.

shard: a sharp broken piece of pottery or glass

funerary: relating to a funeral or burial

ritual: a set of actions performed in a special order, often for religious or social reasons

phenomenon: a remarkable or notable event or pattern

residue: a small amount of substance left after a process

molecular: relating to molecules, the small chemical units of matter

borderland: a region between two places or cultures

communal: shared by a group rather than belonging to one person

A collaborative team from the University of Warsaw and Lodz University of Technology has reported the earliest molecular evidence of fermented alcoholic beverages in the northeastern reaches of Poland, drawn from pottery sherds recovered at the funerary and ceremonial sites of Supraśl in the Northern Podlasie Lowland and Skrzeszew in the Mazovian Lowland. The findings, published in Archaeometry, extend the documented chemistry of brewing on the European North-East plain by several centuries.

The ceramic assemblage is attributable predominantly to the Bell Beaker phenomenon, the late-third-millennium BCE horizon whose distinctive campaniform vessels mark a vast swathe of prehistoric Europe. Although the culture's expansion has been variously characterized as migratory, ideological, or commercial, its ritual practices appear to have included the conspicuous consumption of fermented beverages, a behaviour now newly substantiated for this borderland.

Through targeted organic residue analysis, the investigators identified lipid and carbohydrate biomarkers consistent with cereal-based fermentation. Several specimens further preserve compounds suggestive of a more elaborate mixed-fermentation beverage—the so-called Nordic grog tradition documented elsewhere in Bronze Age Scandinavia—implying a degree of recipe sophistication that earlier reconstructions of the Polish Neolithic had not foregrounded.

The authors are appropriately circumspect: chemistry alone cannot illuminate the social grammar of consumption. Yet the depositional contexts—graves, pits, ceremonial enclosures—are eloquent. Whoever the drinkers were, they appear to have used fermented liquids to lubricate negotiations among the living and to mediate the symbolic frontiers between the living and the dead, a function alcohol has played in countless human societies since.

sherds: broken pieces of pottery, especially from archaeology

campaniform: shaped like a bell

ideological: relating to a system of ideas or beliefs

conspicuous: highly visible or noticeable

lipid: a fat or fat-like substance studied in chemistry

biomarker: a measurable molecule that points to a particular biological process

circumspect: cautious; aware of possible consequences

enclosure: an area surrounded by a barrier or boundary
