Short answers, pulled from the story.
An alcoholic beverage is any drink containing alcohol, a central nervous system depressant. They are typically divided into three classes, beers, wines, and spirits, with alcohol content usually between 3 percent and 50 percent. People primarily drink them for the psychoactive effects they produce.
The oldest verifiable brewery was found in a prehistoric burial site in a cave near Haifa in modern-day Israel, with 13,000-year-old beer residue thought to have been used for ritual feasts. The earliest winemaking was dated to between 6,000 and 5,800 BCE in Georgia in the South Caucasus, and the oldest surviving wine is the Carmona Wine Urn, a first century Roman vessel found in 2019 in Spain.
Wine, beer, and spirits are produced by yeasts, single-celled fungi, most commonly from the genus Saccharomyces, whose name means sugar fungus. When oxygen is absent, the yeast only partially breaks down sugars, turning glucose into alcohol, carbon dioxide, and energy. If a fermented mash is then distilled, the drink becomes a spirit.
Fermented beverages such as beer, wine, mead, and cider are produced directly by yeast activity, while distilled beverages are made by concentrating fermented ethanol through distillation. Unsweetened distilled drinks of at least 20 percent ABV are called spirits, and common ones like whisky and vodka are around 40 percent.
The temperance movement advocated against alcohol consumption and grew in the United States, United Kingdom, Canada, Scandinavia, and India in the nineteenth century. It led to national prohibitions in Canada from 1918 to 1920, Norway for spirits from 1919 to 1926, Finland from 1919 to 1932, and the United States from 1920 to 1933.
Alcohol is classified as a group 1 carcinogen, and the World Health Organization considers no quantity of consumption to be risk free. In 2023 the WHO stated that risk to a drinker's health starts from the first drop, and in 2025 U.S. Surgeon General Dr. Vivek Murthy argued for cancer warning labels on alcohol products.
