Drink
A drink or beverage is a liquid intended for human consumption. In addition to their basic function of satisfying thirst, drinks play important roles in human culture. Common types of drinks include plain drinking water, milk, juice, smoothies and soft drinks. Traditionally warm beverages encompass coffee, tea, and hot chocolate. Caffeinated drinks that contain the stimulant caffeine, have been consumed for centuries.
In addition, alcoholic drinks such as wine, beer, and liquor, which contain the psychoactive substance ethanol, have been part of human culture for more than 8,000 years. Non-alcoholic drinks typically refer to beverages that are traditionally alcoholic—such as beer, wine, or cocktails—but are produced with a very low alcohol by volume content. This category includes beverages that have undergone processes to remove or significantly reduce alcohol, such as non-alcoholic beers and de-alcoholized wines.
Biology
When the human body becomes dehydrated, a person experiences thirst. This craving of fluids results in an instinctive need to drink. Thirst is regulated by the hypothalamus in response to subtle changes in the body's electrolyte levels, and also as a result of changes in the volume of blood circulating. The complete deprivation of drinks will result in death faster than the removal of any other substance besides oxygen. Water and milk have been basic drinks throughout history. As water is essential for life, it has also been the carrier of many diseases.As society developed, techniques were discovered to create alcoholic drinks from the plants that were available in different areas. The earliest archaeological evidence of wine production yet found has been at sites in Georgia and Iran. Beer may have been known in Neolithic Europe as far back as 3000 BCE, and was mainly brewed on a domestic scale. The invention of beer has been argued to be responsible for humanity's ability to develop technology and build civilization. Tea likely originated in Yunnan, China, during the Shang dynasty as a medicinal drink.
History
has been a large part of socialising throughout the centuries. In ancient Greece, a social gathering for the purpose of drinking was known as a symposium, where watered down wine would be drunk. The purpose of these gatherings could be anything from serious discussions to direct indulgence. In ancient Rome, a similar concept of a convivium took place regularly.Many early societies considered alcohol a gift from the gods, leading to the creation of gods such as Dionysus. Other religions forbid, discourage, or restrict the drinking of alcoholic drinks for various reasons. In some regions with a dominant religion the production, sale, and consumption of alcoholic drinks is forbidden to everybody, regardless of religion.
Toasting is a method of honoring a person or wishing good will by taking a drink. Another tradition is that of the loving cup, at weddings or other celebrations such as sports victories a group will share a drink in a large receptacle, shared by everyone until empty.
In East Africa and Yemen, coffee was used in native religious ceremonies. As these ceremonies conflicted with the beliefs of the Christian church, the Ethiopian Church banned the secular consumption of coffee until the reign of Emperor Menelik II. The drink was also banned in Ottoman Turkey during the 17th century for political reasons and was associated with rebellious political activities in Europe.
Production
A drink is a form of liquid which has been prepared for human consumption. The preparation can include a number of different steps, some prior to transport, others immediately prior to consumption.Purification of water
Water is the chief constituent in all drinks, and the primary ingredient in most. Water is purified prior to drinking. Methods for purification include filtration and the addition of chemicals, such as chlorination. The importance of purified water is highlighted by the World Health Organization, who point out 94% of deaths from diarrhea – the third biggest cause of infectious death worldwide at 1.8 million annually – could be prevented by improving the quality of the victim's environment, particularly safe water.Pasteurization
is the process of heating a liquid for a period of time at a specified temperature, then immediately cooling. The process reduces the growth of microorganisms within the liquid, thereby increasing the time before spoilage. It is primarily used on milk, which prior to pasteurization is commonly infected with pathogenic bacteria and therefore is more likely than any other part of the common diet in the developed world to cause illness.Juicing
The process of extracting juice from fruits and vegetables can take a number of forms. Simple crushing of most fruits will provide a significant amount of liquid, though a more intense pressure can be applied to get the maximum amount of juice from the fruit. Both crushing and pressing are processes used in the production of wine.Infusion
is the process of extracting flavors from plant material by allowing the material to remain suspended within water. This process is used in the production of teas, herbal teas and can be used to prepare coffee.Percolation
The name is derived from the word "percolate" which means to cause to pass through a permeable substance especially for extracting a soluble constituent. In the case of coffee-brewing the solvent is water, the permeable substance is the coffee grounds, and the soluble constituents are the chemical compounds that give coffee its color, taste, aroma, and stimulating properties.Carbonation
is the process of dissolving carbon dioxide into a liquid, such as water.Fermentation
Fermentation is a metabolic process that converts sugar to ethanol. Fermentation has been used by humans for the production of drinks since the Neolithic age. In winemaking, grape juice is combined with yeast in an anaerobic environment to allow the fermentation. The amount of sugar in the wine and the length of time given for fermentation determine the alcohol level and the sweetness of the wine.When brewing beer, there are four primary ingredients – water, grain, yeast and hops. The grain is encouraged to germinate by soaking and drying in heat, a process known as malting. It is then milled before soaking again to create the sugars needed for fermentation. This process is known as mashing. Hops are added for flavouring, then the yeast is added to the mixture to start the fermentation process.
Distillation
Distillation is a method of separating mixtures based on differences in volatility of components in a boiling liquid mixture. It is one of the methods used in the purification of water. It is also a method of producing spirits from milder alcoholic drinks.Mixing
An alcoholic mixed drink that contains two or more ingredients is referred to as a cocktail. Cocktails were originally a mixture of spirits, sugar, water, and bitters. The term is now often used for almost any mixed drink that contains alcohol, including mixers, mixed shots, etc. A cocktail today usually contains one or more kinds of spirit and one or more mixers, such as soda or fruit juice. Additional ingredients may be sugar, honey, milk, cream, and various herbs.Type
Non-alcoholic drinks
A non-alcoholic drink is one that contains little or no alcohol. This category includes low-alcohol beer, non-alcoholic wine, and apple cider if they contain a sufficiently low concentration of alcohol by volume. The exact definition of what is "non-alcoholic" and what is not depends on local laws: in the United Kingdom, "alcohol-free beer" is under 0.05% ABV, "de-alcoholised beer" is under 0.5%, while "low-alcohol beer" can contain no more than 1.2% ABV. The term "soft drink" specifies the absence of alcohol in contrast to "hard drink" and "drink". The term "drink" is theoretically neutral, but often is used in a way that suggests alcoholic content. Drinks such as soda pop, sparkling water, iced tea, lemonade, root beer, fruit punch, milk, hot chocolate, tea, coffee, milkshakes, tap water, bottled water, juice, and energy drinks are all soft drinks.Water
Water is the world's most consumed drink, however, 97% of water on Earth is non-drinkable salt water. Fresh water is found in rivers, lakes, wetlands, groundwater, and frozen glaciers. Less than 1% of the Earth's fresh water supplies are accessible through surface water and underground sources which are cost effective to retrieve.In western cultures, water is often drunk cold. In the Chinese culture, it is typically drunk hot.
Milk
is regarded as one of the "original" drinks; milk is the primary source of nutrition for babies. In many cultures of the world, especially the Western world, humans continue to consume dairy milk beyond infancy, using the milk of other animals as a drink.Carbonated drinks
Carbonated drinks refer to drinks which have carbon dioxide dissolved into them. This can happen naturally through fermenting and in natural water spas or artificially by the dissolution of carbon dioxide under pressure. The first commercially available artificially carbonated drink is believed to have been produced by Thomas Henry in the late 1770s.Cola, orange, various roots, ginger, and lemon/lime are commonly used to create non-alcoholic carbonated drinks; sugars and preservatives may be added later.
The most consumed carbonated soft drinks are produced by three major global brands: Coca-Cola, PepsiCo and the Dr Pepper Snapple Group.
Hot drinks
These drinks are often served warm or hot.Coffee
is a brewed drink prepared from the roasted seeds of several species of an evergreen shrub of the genus Coffea. The two most common sources of coffee beans are the highly regarded Coffea arabica, and the "robusta" form of the hardier Coffea canephora. Coffee plants are cultivated in more than 70 countries. Once ripe, coffee "berries" are picked, processed, and dried to yield the seeds inside. The seeds are then roasted to varying degrees, depending on the desired flavor, before being ground and brewed to create coffee.Coffee is slightly acidic and can have a stimulating effect on humans because of its caffeine content. It is one of the most popular drinks in the world. It can be prepared and presented in a variety of ways. The effect of coffee on human health has been a subject of many studies; however, results have varied in terms of coffee's relative benefit.
Coffee cultivation first took place in southern Arabia; the earliest credible evidence of coffee-drinking appears in the middle of the 15th century in the Sufi shrines of Yemen.
Coffee may have been used socially in the renaissance period of the 17th century. The increasing trades between Europe and North Africa regions made coffee more widely available to Europeans gathering at social locations that served coffee, possibly contributing to the growth of coffeehouses.
