Origin of Wine

Tracking the History of Grapevine Cultivation in Georgia

1. Background and Research Goals

  • The Near East and Caucasus are considered the primary domestication centers of grapevine.

  • The earliest chemical evidence of wine production (6000–5800 BC) was discovered in Neolithic sites in Georgia.

  • This study seeks to:

    • Identify the earliest domesticated grapevines in Georgia.

    • Explore the evolution of cultivated grape diversity over time.

    • Compare ancient grape morphotypes with modern cultivars using DNA analysis.


2. Methodology: Combining Archaeology, Morphometrics, and Genomics

The study analyzed grape pips from 14 archaeological sites using two key methods:

A. Geometric Morphometrics (GMM)

  • Shape analysis of over 500 ancient grape seeds from different periods.

  • Comparison with modern wild and cultivated grape varieties to determine domestication status.

B. Ancient DNA (aDNA) Analysis

  • DNA extracted from charred and uncharred pips to examine genetic continuity.

  • DNA sequences compared to a large public database of grapevine cultivars.

C. Radiocarbon Dating

  • Direct C-14 dating was performed to confirm the chronology of the samples.


3. Key Findings

A. Earliest Domesticated Grapevines (1000 BC Onward)

  • The most ancient grape pip (wild-type) dates to 1900–1500 BC (Middle Bronze Age).

  • The earliest domesticated-type pips appear around 1000 BC (Late Bronze Age).

  • Domesticated grapevines increased significantly in later periods.

B. Morphological Diversity of Ancient Grapes

  • The study found a high diversity of domesticated grape morphotypes over time.

  • Ancient pips closely resemble modern Caucasian, Balkan, and Near Eastern cultivars.

  • The transition from wild to cultivated vines was gradual and occurred over centuries.

C. Ancient DNA Confirms Genetic Links to Modern Varieties

  • DNA successfully recovered from medieval and historic samples.

  • Ancient pips show close genetic ties to modern Georgian grape varieties.

  • A sample from Tsitsamuri (15th-16th century AD) closely matches the modern "Adreuli Skelkana" variety.

D. Evidence of Early Winemaking

  • Chemical evidence shows that wine was produced in Georgia as early as 6000 BC.

  • However, domesticated grapevines only appeared later (~1000 BC), suggesting that early wines may have been made from wild grapes.


4. Implications for the History of Viticulture

A. Georgia as a Cradle of Wine

  • The study reinforces Georgia’s role as one of the earliest wine-producing regions.

  • The genetic continuity between ancient and modern grapes indicates a deep-rooted viticultural tradition.

B. Wild Grapes May Have Been Used for Early Winemaking

  • The gap between early wine production (6000 BC) and domesticated grape cultivation (1000 BC) suggests that wild grapes were initially used for fermentation.

C. The Evolution of Grapevine Cultivation

  • Early grape cultivation likely involved gradual domestication of wild vines through human selection.

  • Georgian grape diversity has been shaped over millennia, with genetic influence from the Near East and Balkans.

The Noah Hypothesis

1. Origins of Domesticated Grapevines

  • The Noah Hypothesis parallels the Eve Hypothesis in human genetics, which traces human ancestry to a single maternal ancestor.

  • Researchers are attempting to trace all modern grape cultivars back to a single wild Eurasian grape ancestor.

  • The domestication of Vitis vinifera involved a long period of experimentation before Neolithic societies developed sophisticated viticulture.


2. Biblical and Mythological Parallels

  • The biblical Noah’s first act after the flood was to plant a vineyard (Genesis 9:20).

  • Similar flood myths exist in Mesopotamian legends, such as the Epic of Gilgamesh, where Utnapishtim, the flood survivor, also has associations with wine and vineyards.

  • The Gilgamesh tale references Siduri, a tavern keeper, highlighting the early role of fermented beverages in civilization.

  • These stories suggest that wine held cultural and religious importance from early times.


3. Archaeological and Genetic Evidence

  • Chemical analyses of ancient pottery suggest that wine production began in the Neolithic period (~6000 BC).

  • Archaeological sites in Georgia, Armenia, and Turkey contain:

    • Early grape seeds with domesticated traits.

    • Pottery vessels with wine residues.

    • Winemaking tools and storage containers.

  • The work of Russian botanist Nikolai Vavilov identified Transcaucasia as the cradle of viniculture.

  • Genetic research has identified distinct grape families, such as:

    • Occidentalis (Western Europe, colder climates).

    • Orientalis (Central Asia, larger berries).

    • Pontica (Eastern Europe, moderate acidity, ideal for wine).


4. The Role of Transcaucasia in Early Viticulture

  • The Greater Caucasus Mountains provided ideal conditions for wild grape growth and human settlement.

  • Neolithic sites like Shulaveris-Gora (6000 BC, Georgia) have yielded evidence of early wine production.

  • Early viticulture likely spread from Transcaucasia to the Mediterranean through trade and migration.


5. Linguistic Evidence of Early Wine Culture

  • Many languages share a common root for "wine", suggesting early diffusion:

    • Latin: vinum

    • Greek: wo-no (Linear B)

    • Hittite: wijana

    • Hebrew: yayin

    • Kartvelian (Georgian): ghvino

  • The spread of this term supports the early movement of viniculture from Transcaucasia to the Mediterranean and Europe.


6. The Black Sea Flood Hypothesis

  • A competing theory, Ryan and Pitman’s Black Sea Flood Hypothesis, suggests that the Black Sea flooded catastrophically around 5600 BC, displacing populations.

  • This could have accelerated the spread of agriculture and viticulture, as displaced farmers carried their knowledge to new regions.


7. DNA Research and Modern Implications

  • DNA studies are tracing ancient grape lineages to determine whether viniculture had a single point of origin or multiple domestication sites.

  • The Ancient DNA Grape Project aims to extract and analyze genetic material from archaeological remains.

  • Modern grape varieties may still carry genetic markers of ancient domesticated vines.
