Evidence of world's earliest winemaking uncovered by archaeologists | Evidence of world's earliest winemaking uncovered by archaeologists |

A series of excavations in Georgia has uncovered evidence of the world’s earliest winemaking, in the form of telltale traces within clay pottery dating back to 6,000BC – suggesting that the practice of making grape wine began hundreds of years earlier than previously believed. | A series of excavations in Georgia has uncovered evidence of the world’s earliest winemaking, in the form of telltale traces within clay pottery dating back to 6,000BC – suggesting that the practice of making grape wine began hundreds of years earlier than previously believed. |
While there are thousands of cultivars of wine around the world, almost all derive from just one species of grape, with the Eurasian grape the only species ever domesticated. | While there are thousands of cultivars of wine around the world, almost all derive from just one species of grape, with the Eurasian grape the only species ever domesticated. |
Until now, the oldest jars known to have contained wine dated from 7,000 years ago, with six vessels containing the chemical calling cards of the drink discovered in the Zagros mountains in northern Iran in 1968. | Until now, the oldest jars known to have contained wine dated from 7,000 years ago, with six vessels containing the chemical calling cards of the drink discovered in the Zagros mountains in northern Iran in 1968. |
The latest find pushes back the early evidence for the tipple by as much as half a millennium. | The latest find pushes back the early evidence for the tipple by as much as half a millennium. |
“When we pick up a glass of wine and put it to our lips and taste it we are recapitulating that history that goes back at least 8,000 years,” said Patrick McGovern a co-author of the study from the University of Pennsylvania museum of archaeology and anthropology, who also worked on the earlier Iranian discovery. | “When we pick up a glass of wine and put it to our lips and taste it we are recapitulating that history that goes back at least 8,000 years,” said Patrick McGovern a co-author of the study from the University of Pennsylvania museum of archaeology and anthropology, who also worked on the earlier Iranian discovery. |
The find comes after a team of archaeologists and botanists in Georgia joined forces with researchers in Europe and North America to explore two villages in the South Caucasus region, about 50km south of the capital Tbilisi. | The find comes after a team of archaeologists and botanists in Georgia joined forces with researchers in Europe and North America to explore two villages in the South Caucasus region, about 50km south of the capital Tbilisi. |
The sites offered a glimpse into a neolithic culture characterised by circular mud-brick homes, tools made of stone and bone and the farming of cattle, pigs, wheat and barley. | The sites offered a glimpse into a neolithic culture characterised by circular mud-brick homes, tools made of stone and bone and the farming of cattle, pigs, wheat and barley. |
Researchers were particularly intrigued by fired clay pots found in the region – likely to be some of the earliest pottery made in the Near East. Indeed, one representative jar from a nearby settlement is almost a metre tall and a metre wide, and could hold more than 300 litres. What’s more, it was decorated with blobs that the researchers say could be meant to depict clusters of grapes. | Researchers were particularly intrigued by fired clay pots found in the region – likely to be some of the earliest pottery made in the Near East.

To explore whether winemaking was indeed a part of life in the region, the team focused on collecting and analysing fragments of pottery from two neolithic villages, as well as soil samples. Radiocarbon dating of grains and charcoal nearby suggested the pots date to about 6,000–5,800 BC. | To explore whether winemaking was indeed a part of life in the region, the team focused on collecting and analysing fragments of pottery from two neolithic villages, as well as soil samples.

In total, 30 pottery fragments and 26 soil samples were examined, with the inside surface of the pottery ground down a little to produce a powder for analysis. While many of the pieces were collected in recent excavations, two were collected in the 1960s; researchers have long suspected they might bear traces of wine. | In total, 30 pottery fragments and 26 soil samples were examined, with the inside surface of the pottery ground down a little to produce a powder for analysis.

The team then used a variety of analytical techniques to explore whether the soil or the inner surface of the vessels held signs of molecules of the correct mass, or with the right chemical signatures, to be evidence of wine. | The team then used a variety of analytical techniques to explore whether the soil or the inner surface of the vessels held signs of molecules of the correct mass, or with the right chemical signatures, to be evidence of wine. |
The results, published in the Proceeding of the National Academy of Sciences, reveal that for eight of the fragments, including the two previously unearthed, the team found traces of tartaric acid – a substance found in grapes in large quantities. Tests on the associated soils largely showed far lower levels of the acid. The team also identified the presence of three other acids linked to grapes and wine. Other evidence indicating the presence of wine included ancient grape pollen found at the excavated sites – but not in the topsoil – as well as grape starch particles, the remains of a fruit fly, and cells believed to be from the surface of grapevines on the inside of one of the fragments. | The results, published in the Proceeding of the National Academy of Sciences, reveal that for eight of the fragments, including the two previously unearthed, the team found traces of tartaric acid – a substance found in grapes in large quantities.

While the team note that it is possible that the vessels were used to store something other than wine, such as the grapes themselves, they note that the shape of the vessels is suited to holding a liquid and that grapes or raisins would have degraded without trace. Moreover, there are none of the telltale signs that the pots were used for syrup-making, while grape juice would have fermented within a matter of days. | While the team note that it is possible that the vessels were used to store something other than wine, such as the grapes themselves, they note that the shape of the vessels is suited to holding a liquid and that grapes or raisins would have degraded without trace.

The findings suggest the sites were home to the earliest known vintners, besting the previous record held by the traces of Iranian wine found just 500km away and dated to 5,400-5,000 BC. Older remnants of winemaking have also been found at the Jiahu site in China’s Henan province, dating back to 7,000BC, but the fermented liquid appeared to be a mixture of grapes, hawthorn fruit, rice beer and honey mead. | The findings suggest the sites were home to the earliest known vintners, besting the previous record held by the traces of Iranian wine found just 500km away and dated to 5,400-5,000 BC.

With their narrow base, the large clay pots used do not stand up easily, suggesting they might have been half buried in the ground during the winemaking process, as was the case for the Iranian vessels and which is a traditional practice still used by some in Georgia. | With their narrow base, the large clay pots used do not stand up easily, suggesting they might have been half buried in the ground during the winemaking process, as was the case for the Iranian vessels and which is a traditional practice still used by some in Georgia. |
Davide Tanasi, of the University of South Florida, said the results of the study were unquestionable and that the findings were “certainly the example of the oldest pure grape wine in the world”. | Davide Tanasi, of the University of South Florida, said the results of the study were unquestionable and that the findings were “certainly the example of the oldest pure grape wine in the world”. |

“The Georgians are absolutely ecstatic,” said Stephen Batiuk, an archaeologist from the University of Toronto and one of the study’s co-authors. “They have been saying for years that they have a very long history of winemaking and so we’re really cementing that position.” | “The Georgians are absolutely ecstatic,” said Stephen Batiuk, an archaeologist from the University of Toronto and one of the study’s co-authors. “They have been saying for years that they have a very long history of winemaking and so we’re really cementing that position.” |
