Bulgarian find points to beer brewing 6,500 years ago
Germinated emmer wheat in a prehistoric house may point to malting, but does not yet prove this was Europe’s oldest beer.
Archaeologists report indications of beer production at the Bulgarian site of Provadia-Solnitsata. The find consists of charred, germinated grains; the researchers cautiously describe it as possible evidence of very early beer production.
The indications were found during excavations at Provadia-Solnitsata, a prehistoric centre known for salt production and early urban development. According to the archaeologists, the house under examination dates from around 4500 BC, in the Late Copper Age.
Two upturned ceramic bowls contained charred ears of emmer wheat. According to the excavation site’s description, the grains had germinated. This is relevant because grain must first be soaked and allowed to germinate to make malt. This activates enzymes that convert starch into sugars.
The researchers infer that the grain may have been deliberately processed for malting. Malting is an important step in brewing beer, but in itself is not direct evidence that a fermented drink was also made in the vessel. Additional chemical residues, production tools or a broader context would be needed for that.
The find was presented by excavation leader Vasil Nikolov. The Bulgarian news organisation BTA described the discovery as possibly the earliest evidence of beer production in Bulgaria and perhaps in Europe. That wording is important: this is a provisional interpretation of archaeological finds, not an established ranking of Europe’s oldest beers.
There are already other claims about very early beer in Europe. The University of Vienna, for example, described archaeobotanical evidence of malted barley from Hornstaad, published in 2021. Older traces of beer fermentation have also been reported in Spain. Such comparisons depend on precisely what is being measured: fermentation residues, malted grain or a complete brewing installation.
The Bulgarian find is nevertheless interesting because it suggests a concrete production process. The grains were not merely present; according to the researchers, they showed characteristics consistent with controlled germination. This makes human processing more plausible than when only loose grains are found in a settlement.
For now, the status of the research is that of an archaeological find and an initial interpretation. The public sources consulted contain no peer-reviewed publication in which the dating, grain analysis and any chemical residues have been independently assessed.
The safest conclusion is therefore a modest one: around 4500 BC, people at Provadia-Solnitsata processed emmer wheat in a way consistent with malting. Whether they actually brewed beer with it, and whether this was Europe’s oldest beer production, will require further research.

Editor's note
The find and the interpretation of germinated emmer wheat were reported by the excavation site and BTA. The status is provisional; there was no peer-reviewed publication or independent confirmation that this was Europe’s oldest beer.Sources
