Reconstruction
On the lowlands south of the Caucasus, early farming communities stored food and drink in large pottery vessels. Several Neolithic jars excavated at Gadachrili Gora and the nearby site of Shulaveris Gora retained compounds absorbed into their ceramic fabric. Chemical analysis detected tartaric acid or its salts together with a supporting pattern of other organic acids. Because grapes are exceptionally rich in tartaric acid and Eurasian grapevines grew in the region, the residues are widely interpreted as evidence of grape wine dating to roughly 6000–5800 BCE. They rank among the earliest secure chemical indications of wine made primarily from grapes.
The vessels do not preserve a recipe. A reasonable reconstruction begins with ripe grapes gathered in late summer or autumn, crushed so that juice contacted naturally occurring yeasts on the skins, and left in a jar to ferment. The large containers could have served for production, storage, or both. Whether their mouths were sealed, whether skins and stems remained in the liquid, and whether herbs or other ingredients were added are unknown. Fermentation would have extended the usefulness of a highly seasonal fruit, although Neolithic wine was probably less standardized and less stable than most commercial wine today.
Nor does the chemistry by itself prove fully developed viticulture. Wild Vitis vinifera was native to the wider region, and the residues cannot establish whether the grapes came from tended wild vines, cultivated vines, or domesticated varieties. Archaeobotanical evidence shows that grapes were available, but the transition from gathering to deliberate vineyard management was gradual and remains difficult to date at individual settlements. “Wine production” is therefore better supported here than “vine domestication.”
Even with those limits, the jars reveal an important combination of ecological knowledge and ceramic technology. Villagers had to recognize fruit ripeness, gather substantial quantities within a short season, manage fermentation, and keep the resulting liquid from excessive exposure or spoilage. Wine may have been consumed within households, shared during communal meals, exchanged, or used ceremonially. Such social roles are plausible from later wine cultures, but they cannot be read directly from the chemical residues.
The South Caucasian evidence belongs to a much longer history in which grape wine became a trade commodity, marker of hospitality, ritual substance, and everyday drink across western Asia, the Mediterranean, and beyond. Modern Georgian winemaking in buried or freestanding earthenware vessels called qvevri offers a striking technological comparison, but it should not be treated as an uninterrupted recipe documented from these Neolithic jars. The defensible connection is broader: pottery, grapes, microorganisms, and practiced observation already supported deliberate fermentation eight thousand years ago.

Historical context
The South Caucasus contained settled farming villages rather than cities or states. Communities cultivated cereals and pulses, kept domesticated animals, and made pottery while also using local wild resources. Writing and wheeled transport had not yet appeared, and metal use was rare. Farming had already been established for millennia in parts of Southwest Asia and was spreading farther into Europe. Obsidian and other materials moved through regional exchange networks over tens or sometimes hundreds of kilometres, connecting villages whose food production remained strongly seasonal.
Evidence
Archaeological
StrongExcavated Neolithic pottery vessels provide secure archaeological contexts for the absorbed residues.
Residue chemical
StrongTartaric acid or tartrate and a supporting suite of organic compounds were detected in multiple vessel samples, with controls used to assess environmental background.
Archaeobotanical
ModerateRegional plant evidence supports the availability of grapes, but it does not establish that the particular residue-bearing jars held fruit from domesticated vines.
Food identification
StrongThe chemical pattern and regional ecology make grape-derived fermented liquid the best-supported identification, although no surviving liquid permits direct characterization.
Dating
StrongThe residue-bearing vessels come from well-dated early Neolithic occupation contexts, generally placed around 6000–5800 BCE rather than a single exact year.
Preparation method
ProbableCrushing grapes and allowing juice to ferment in pottery is a reasonable reconstruction, but crushing equipment, fermentation duration, filtering, sealing, and additives were not directly observed.
Geographic attribution
StrongThe principal finds are securely attributed to early farming settlements in present-day Georgia's South Caucasian lowlands.
Historical interpretation
ModerateDeliberate grape fermentation is well supported; claims about vineyard cultivation, ritual use, trade, social rank, or continuity with later Georgian techniques remain inferential.
Limitations
- moderatedate start/date end
An exact date of 6000 BCE implies unsupported precision. The relevant occupation and residue evidence are generally assigned to approximately 6000–5800 BCE.
- moderatecoordinates
The supplied coordinates lie in or near Tbilisi and do not appear to mark Gadachrili Gora itself, which is farther south in the Marneuli area.
