A drink or beverage is a liquid intended for human consumption. In addition to basic needs, beverages form part of the culture of human society. Although all beverages, including juice, soft drinks, and carbonated drinks, have some form of water in them, water itself is often not classified as a beverage, and the word ''beverage'' has been recurrently defined as not referring to water. An alcoholic beverage is a drink containing ethanol, commonly known as alcohol, although in chemistry the definition of an alcohol includes many other compounds. Alcoholic beverages, such as wine, beer, and liquor, have been part of human culture and development for 8,000 years. Non-alcoholic beverages often signify drinks that would normally contain alcohol, such as beer and wine but are made with less than .5 percent alcohol by volume. The category includes drinks that have undergone an alcohol removal process such as non-alcoholic beers and de-alcoholized wines. ==Biology== When the human body becomes dehydrated it experiences the sensation of ''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 elimination of beverages, i.e. water, from the body will result in death faster than the removal of any other substance. 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 mankind evolved, new techniques were discovered to create drinks from the plants that were native to their areas. The earliest archaeological evidence of wine production yet found has been at sites in Georgia ( BC) and Iran ( BC). Beer may have been known in Neolithic Europe as far back as 3000 BC,〔() ''Prehistoric brewing: the true story'', 22 October 2001, Archaeo News. Retrieved 13 September 2008〕 and was mainly brewed on a domestic scale.〔() Dreher Breweries, ''Beer-history''〕 The invention of beer (and bread) 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 (1500 BC–1046 BC) as a medicinal drink. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「drink」の詳細全文を読む スポンサード リンク
