Alcoholic drink

Production and key components

Most alcoholic drinks begin with fermentation, a biochemical process in which microorganisms convert carbohydrates into alcohol and related products. Yeasts are the most common fermenting agents, but other microbes such as bacteria can influence flavor and chemistry. The fermentable material is often sugars derived from grain, fruit, or honey; fermentation can also yield acetic acid and vinegar if oxygen is present or other bacteria act on the product. When stronger beverages are desired, producers commonly use distillation to concentrate ethanol and remove some impurities.

Categories and examples

Alcoholic drinks are frequently grouped by how they are made and their typical alcohol content. These broad categories help describe style, production method and expected strength:

• Fermented low-strength beverages: beers, meads and ciders, typically produced by fermenting cereals, honey or fruit and usually containing modest amounts of ethanol.
• Wines and related fermented beverages: grape wine and rice-based drinks such as sake, made from fermented sugars and often aged or blended to develop aroma and complexity.
• Distilled spirits: products concentrated by distillation from fermented mash, including examples such as rum (rum), vodka, gin and whiskies; these are usually labeled by alcoholic proof or percentage.

Commercial varieties and hybrids

In addition to traditional types, many countries sell mixed or flavored beverages that combine distilled alcohol with fruit juices, sweeteners or carbonated bases. One common commercial category is alcopops, sweetened ready-to-drink products that often use distilled spirits as a base and are marketed in bright packaging. The composition and marketing of such drinks have prompted specific regulation in some jurisdictions, particularly where authorities worry about appeal to younger consumers. Rules about retail sale and age limits frequently distinguish between beer-like products (beer) and distilled spirits.

Effects on people and health considerations

Ethanol acts on the central nervous system and is widely reported to produce feelings of relaxation and sociability at low doses; it is one of the world’s most commonly used recreational drugs. Because of its psychoactive effects some people develop problematic patterns of consumption or dependence. Excessive or prolonged use can lead to overuse and, in severe cases, clinical alcoholism (alcohol use disorder). Acute heavy drinking causes intoxication (being "drunk"), which impairs judgment, coordination and reaction time. Although ethanol is less toxic to humans than many other alcohols, the human body still treats it as a chemical toxin and metabolizes it through liver enzymes; very high doses can be life-threatening.

History, cultural role and safety

People have deliberately produced and consumed alcoholic drinks for millennia; archaeological and historical records indicate fermentation and early forms of brewing and winemaking in many ancient societies. Distilled spirits became widespread after technology for distillation improved, giving rise to beverages such as vodka, gin and various whiskies, as well as high-proof rums (rum) used in cuisine and cocktails. Today alcoholic drinks play roles in culinary arts, religious rites, social rituals and economies, but they are also regulated to reduce harm: age limits, licensing systems and labeling requirements (including disclosure of alcohol content as proof or percentage) are common. Responsible consumption, clear labeling and public education remain central to balancing the cultural importance of alcoholic beverages with their potential health and social risks.
