Overview
A drink, or beverage, is a liquid intended for ingestion by an organism through the mouth. For humans the most common drinks include water, tea, milk, coffee, fruit juice, soft drinks and alcoholic beverages. Drinks may be consumed to quench thirst, supply nutrients, deliver stimulants or alcohol, or as part of social and religious customs.
Composition and characteristics
Most drinks are composed primarily of water, which is essential to life. They may also contain dissolved sugars, salts, proteins, fats, acids, flavor compounds and micronutrients. Temperature, viscosity, carbonation and pH are common physical or sensory properties that distinguish beverages. Some drinks are formulated for specific effects, such as electrolyte solutions for rehydration or caffeinated beverages for stimulation. If an organism does not receive sufficient liquid it can suffer dehydration, which in severe cases may cause them to die.
Categories and examples
- Non‑alcoholic: plain water, brewed teas and coffees, milk and plant milks, fruit and vegetable juices (juice).
- Carbonated and sweetened soft drinks: sodas and flavored waters.
- Alcoholic: beers, wines and distilled spirits (alcoholic).
- Functional and specialty: sports drinks, nutritional shakes, infant formulas and medical beverages.
History and cultural roles
Across cultures, beverages have long social, religious and economic roles. Brewing and fermentation are ancient technologies used to produce beer, wine and other fermented drinks. Tea and coffee have shaped trade routes and social rituals; milk and fermented milk products are central in many pastoral societies. Beverage choices and preparation methods reflect local resources, climate and customs.
Health, safety and environmental aspects
Safe drinking water is a fundamental public health priority. Many beverages require safe processing, pasteurization or filtration to prevent contamination. Consumption patterns affect health: excessive sugar or alcohol intake carries risks, while appropriate hydration supports bodily functions. Production and packaging of drinks also have environmental impacts from water use, agriculture and plastics; sustainable sourcing and recycling can mitigate those effects.
Practical considerations and distinctions
Not all liquids are suitable as drinks: potable beverages meet quality standards, whereas some liquids are toxic or unpalatable. Plants absorb water through roots and many land animals obtain needed fluids by drinking rather than directly from the environment. In everyday life, drinks are chosen for hydration, nutrition, taste or ritual significance, and their wide variety reflects human cultural and technological diversity.
