Use Estreicher, “Distillation and Distilled Wines,” page 129, for the concise documentary claim. Consult Cockx, Meloni, and Swinnen and surviving al-Kindi text for priority analysis.
By around 866 CE, al-Kindi discussed distillation of date-palm wine in the Book of the Chemistry of Perfume and Distillations; this is a documentary milestone for alcohol distillation, not an uncontested invention claim.
Reverified on 2026-09-02 against the complete official Cambridge PDF attached to the Source, page 129.
Do not call al-Kindi the inventor of alcohol distillation without reviewing the underlying specialist scholarship. The date is approximate.
The reviewed source directly dates al-Kindi’s discussion and qualifies likely production scale. The claim retains the documentary fact while removing the source’s stronger priority language.
Used and link-verified on the public history page “Before American Whiskey — Fermentation, Distillation, and Transatlantic Knowledge” on 2026-09-02. Retain the recorded qualifications in future revisions.
