Study Notes
- Chimpanzees can stumble upon overripe plums and experience strange effects due to the fermentation process.
- Sugars in overripe fruit attract yeasts, which produce ethanol (alcohol) through fermentation.
Early Fermented Beverages
- The earliest evidence of humans creating alcoholic beverages dates back to 7000 BCE in China.
- Residue in clay pots indicates the use of fermented rice, millet, grapes, and honey.
- Ancient Mesopotamians and Egyptians produced beer from stored cereal grains.
- Beer was a common beverage for all social classes and was included in workers' daily rations.
- Wine was also made but was a rare and expensive delicacy due to the climate.
- In Greece and Rome, wine was readily available due to favorable grape-growing conditions.
- Ancient peoples made alcohol from locally grown crops and plants.
- South Americans made chicha from grains, sometimes adding hallucinogenic herbs.
- In Mexico, pulque, made from cactus sap, was a popular drink.
- East Africans made banana and palm beer.
- In Japan, sake was made from rice.
Societal Views on Alcohol
- As alcohol consumption became widespread, authorities had mixed views.
- Greek physicians considered wine to be good for health, while poets saw it as a creative aid.
- Greek philosophers promoted temperance.
- Early Jewish and Christian writers integrated wine into rituals but viewed excessive intoxication as a sin.
- Islamic cultures in the Middle East, Africa, and Spain eventually banned alcohol due to concerns about praying while drunk.
Distillation
- Ancient fermented beverages had limited alcohol content (around 13%) due to the toxicity of by-products produced by wild yeasts.
- The invention of distillation changed this limitation
- 9th-century Arabic writings describe distillation as boiling fermented liquids to vaporize the alcohol.
- Capturing and cooling the vapor results in a more concentrated liquid alcohol.
- Distilled spirits were initially used for medicinal purposes.
- Spirits became important for trade due to their resistance to spoilage.
- Rum from Caribbean sugar plantations was traded to North America and used by sailors.
- Europeans traded brandy and gin in Africa for enslaved people, land, and goods.
- Spirits became a form of currency in some regions.
Alcohol's Role in Exploration
- During the Age of Exploration, spirits were crucial for long sea voyages.
- Adding brandy to water barrels preserved water and killed harmful microbes.
- By the 1600s, alcohol fueled global trade and exploration.
