Use Estreicher’s section-level citation for the concise timeline anchor and McGovern et al. 2017 for extended archaeological discussion.
Chemical analysis of residue in a Georgian jar supports wine production around 6000 BCE, providing an early fermentation anchor without establishing any direct lineage to whiskey.
Reverified on 2026-09-02 against the complete official Cambridge PDF attached to the Source, page 92. The claim remains a secondary synthesis of McGovern et al. 2017.
The date is approximate. Use the underlying 2017 primary paper for technical residue methodology or more granular dating.
The open-access peer-reviewed review distinguishes grape remains from chemical residue evidence and attributes the Georgian finding to the 2017 archaeological study.

Claim
Chemical residue in a Georgian jar supports wine production around 6000 BCE.
Evidence judgment
The reviewed passage treats chemical residue—not merely grape remains—as evidence of wine and attributes the result to the 2017 archaeological study.
Boundary
The event supplies deep fermentation context. It is not a direct ancestor of whiskey.
Drafting guardrail
Use “around” or “about 6000 BCE.” Consult the primary research for technical archaeological detail.
Readiness decision
