Wine


Wine is an alcoholic drink typically made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol, carbon dioxide, and heat. Different varieties of grapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment, and the production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes involve fermentation of additional crops including, rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry.
Wine has been produced for thousands of years. The earliest evidence of wine is from Georgia, Iran, and Sicily. New World wine has some connection to alcoholic beverages made by the indigenous peoples of the Americas, but is mainly connected to later Viking area of Vinland and Spanish traditions in New Spain. Later, as Old World wine further developed viticulture techniques, Europe would encompass three of the largest wine-producing regions. Today, the five countries with the largest wine-producing regions are in Italy, Spain, France, the United States, and China.
Wine has long played an important role in religion. Red wine was associated with blood by the ancient Egyptians and was used by both the Greek cult of Dionysus and the Romans in their Bacchanalia; Judaism also incorporates it in the Kiddush and Christianity in the Eucharist. Egyptian, Greek, Roman, and Israeli wine cultures are still connected to these ancient roots. Similarly the largest wine regions in Italy, Spain, and France have heritages in connection to sacramental wine, likewise, viticulture traditions in the Southwestern United States started within New Spain as Catholic friars and monks first produced wines in New Mexico and California.

History

The earliest known traces of wine are from Georgia, Iran , and Sicily although there is evidence of a similar alcoholic drink being consumed earlier in China. Wine reached the Balkans by 4500 BC and was consumed and celebrated in ancient Greece, Thrace and Rome. Throughout history, wine has been consumed for its intoxicating effects..
In 2017 the research led by Dr. Patrick E. McGovern, Scientific Director of the Biomolecular Archaeology Project for Cuisine, Fermented Beverages, and Health at the University of Pennsylvania Museum in Philadelphia acknowledged Georgia as the birthplace of wine.
The earliest archaeological and archaeobotanical evidence for grape wine and viniculture, dating to 6000–5800 BC was found on the territory of modern Georgia. Both archaeological and genetic evidence suggest that the earliest production of wine elsewhere was relatively later, likely having taken place in the Southern Caucasus, or the West Asian region between Eastern Turkey, and northern Iran.
The earliest evidence of a rice and grape mixed based fermented drink was found in China, earliest evidence of wine in Georgia from 6000 BC, Iran from 5000 BC, and Sicily from 4000 BC.
One of the earliest known wineries from 4100 BC is the Areni-1 winery in Armenia.

A 2003 report by archaeologists indicates a possibility that grapes were mixed with rice to produce mixed fermented drinks in China in the early years of the seventh millennium BC. Pottery jars from the Neolithic site of Jiahu, Henan, contained traces of tartaric acid and other organic compounds commonly found in wine. However, other fruits indigenous to the region, such as hawthorn, cannot be ruled out. If these drinks, which seem to be the precursors of rice wine, included grapes rather than other fruits, they would have been any of the several dozen indigenous wild species in China, rather than Vitis vinifera, which was introduced there 6000 years later.
The spread of wine culture westwards was most probably due to the Phoenicians who spread outward from a base of city-states along the Mediterranean coast of what are today Lebanon, Israel, Syria, and Palestine. The wines of Byblos were exported to Egypt during the Old Kingdom and then throughout the Mediterranean. Evidence includes two Phoenician shipwrecks from 750 BC discovered by Robert Ballard, whose cargo of wine was still intact. As the first great traders in wine, the Phoenicians seem to have protected it from oxidation with a layer of olive oil, followed by a seal of pinewood and resin, similar to retsina. Although the Nuragic culture in Sardinia already had a custom of consuming wine before the arrival of the Phoenicians.
The earliest remains of Apadana Palace in Persepolis dating back to 515 BC include carvings depicting soldiers from Achaemenid Empire subject nations bringing gifts to the Achaemenid king, among them Armenians bringing their famous wine.
Literary references to wine are abundant in Homer, Alkman, and others. In ancient Egypt, six of 36 wine amphoras were found in the tomb of King Tutankhamun bearing the name "Kha'y", a royal chief vintner. Five of these amphoras were designated as originating from the king's personal estate, with the sixth from the estate of the royal house of Aten. Traces of wine have also been found in central Asian Xinjiang in modern-day China, dating from the second and first millennia BC.

The first known mention of grape-based wines in India is from the late 4th-century BC writings of Chanakya, the chief minister of Emperor Chandragupta Maurya. In his writings, Chanakya condemns the use of alcohol while chronicling the emperor and his court's frequent indulgence of a style of wine known as madhu.
The ancient Romans planted vineyards near garrison towns so wine could be produced locally rather than shipped over long distances. Some of these areas are now world-renowned for wine production. The Romans discovered that burning sulfur candles inside empty wine vessels kept them fresh and free from a vinegar smell. In medieval Europe, the Roman Catholic Church supported wine because the clergy required it for the Mass. Monks in France made wine for years, aging it in caves. An old English recipe that survived in various forms until the 19th century calls for refining white wine from bastard—bad or tainted bastardo wine.
Later, the descendants of the sacramental wine were refined for a more palatable taste. This gave rise to modern viticulture in French wine, Italian wine, Spanish wine, and these wine grape traditions were brought into New World wine. For example, Mission grapes were brought by Franciscan monks to New Mexico in 1628 beginning the New Mexico wine heritage, these grapes were also brought to California which started the California wine industry. Both of these regions eventually evolved into American wine's oldest and largest wine producers respectively. Earlier Viking expeditions of Vinland recorded the first grape vines found in the New World, and prior to the Spanish establishing their American wine grape traditions in California and New Mexico, both France and Britain had unsuccessfully attempted to establish grapevines in Florida and Virginia respectively.

Etymology

The English word "wine" comes from the Proto-Germanic *winam, an early borrowing from the Latin vinum, "wine" or " vine", itself derived from the Proto-Indo-European stem *win-o-. The earliest attested terms referring to wine are the Mycenaean Greek ?????? me-tu-wo ne-wo, meaning "in " or " of the new wine", and ????? wo-no-wa-ti-si, meaning "wine garden", written in Linear B inscriptions. Linear B also includes, inter alia, an ideogram for wine, i.e. ?.
The ultimate Indo-European origin of the word is the subject of continued debate. Some scholars have noted the similarities between the words for wine in Indo-European languages, Kartvelian, and Semitic, pointing to the possibility of a common origin of the word denoting "wine" in these language families. The Georgian word goes back to Proto-Kartvelian *ɣwino-, which is either a borrowing from Proto-Indo-European or the lexeme was specifically borrowed from Proto-Armenian *ɣʷeinyo-, whence Armenian gini. An alternate hypothesis by Fähnrich supposes *ɣwino-, a native Kartvelian word derived from the verbal root *ɣun-. See for more. All these theories place the origin of the word in the same geographical location, Trans-Caucasia, that has been established based on archeological and biomolecular studies as the origin of viticulture.

Styles

Red wine

The red-wine production process involves extraction of color and flavor components from the grape skin. Red wine is made from dark-colored grape varieties. The actual color of the wine can range from violet, typical of young wines, through red for mature wines, to brown for older red wines. The juice from most purple grapes is actually greenish-white; the red color comes from anthocyan pigments present in the skin of the grape; exceptions are the relatively uncommon teinturier varieties, which actually have red flesh and produce red juice.

White wine

Fermentation of the non-colored grape pulp produces white wine. The grapes from which white wine is produced are typically green or yellow. Some varieties are well-known, such as the Chardonnay, Sauvignon, and Riesling. Other white wines are blended from multiple varieties; Tokay, Sherry, and Sauternes are examples of these. Dark-skinned grapes may be used to produce white wine if the wine-maker is careful not to let the skin stain the wort during the separation of the pulp-juice. Pinot noir, for example, is commonly used to produce champagne.
Dry white wine is the most common, derived from the complete fermentation of the wort. Sweet wines are produced when the fermentation is interrupted before all the grape sugars are converted into alcohol. Sparkling wines, which are mostly white wines, are produced by not allowing carbon dioxide from the fermentation to escape during fermentation, which takes place in the bottle rather than in the barrel.

Sparkling wine

Rosé wine

A rosé wine incorporates some of the color from the grape skins, but not enough to qualify it as a red wine. It may be the oldest known type of wine, as it is the most straightforward to make with the skin contact method. The pink color can range from a pale orange to a vivid near-purple, depending on the varietals used and wine-making techniques. There are three primary ways to produce rosé wine: skin contact, saignée, and blending. Rosé wines can be made still, semi-sparkling, or sparkling, with a wide range of sweetness levels from dry Provençal rosé to sweet White Zinfandels and blushes. Rosé wines are made from a wide variety of grapes all over the world.

Dessert wine

Fruit wine

, such as apples and berries, are usually named after the fruit from which they are produced combined with the word "wine" and are generically called fruit wine or country wine. Other than the grape varieties traditionally used for wine-making, most fruits naturally lack either sufficient fermentable sugars, relatively low acidity, yeast nutrients needed to promote or maintain fermentation, or a combination of these three characteristics. This is probably one of the main reasons why wine derived from grapes has historically been more prevalent by far than other types, and why specific types of fruit wine have generally been confined to regions in which the fruits were native or introduced for other reasons.

Mead (honey wine)

Mead, also called honey wine, is created by fermenting honey with water, sometimes with various fruits, spices, grains, or hops. As long as the primary substance fermented is honey, the drink is considered mead. Mead was produced in ancient history throughout Europe, Africa and Asia, and was known in Europe before grape wine.

Starch-based "wine" and wine-based products

Other drinks called "wine", such as barley wine and rice wine, are made from starch-based materials and resemble beer more than traditional wine, while ginger wine is fortified with brandy. In these latter cases, the term "wine" refers to the similarity in alcohol content rather than to the production process. The commercial use of the English word "wine" is protected by law in many jurisdictions.
Some UK supermarkets have been criticised for selling “wine based” drinks, which only contain 75% wine, but which are still marketed as wine. The International Organisation of Vine and Wine requires that a "wine based drink" must contain a minimum of 75% wine, but producers do not have to divulge the nature of the remaining 25%.

Grape varieties

Wine is usually made from one or more varieties of the European species Vitis vinifera, such as Pinot noir, Chardonnay, Cabernet Sauvignon, Gamay and Merlot. When one of these varieties is used as the predominant grape, the result is a "varietal" as opposed to a "blended" wine. Blended wines are not necessarily inferior to varietal wines, rather they are a different style of wine-making.
Wine can also be made from other species of grape or from hybrids, created by the genetic crossing of two species. V. labrusca, V. aestivalis, V. rupestris, V. rotundifolia and V. riparia are native North American grapes usually grown to eat fresh or for grape juice, jam, or jelly, and only occasionally made into wine.
Hybridization is different from grafting. Most of the world's vineyards are planted with European V. vinifera vines that have been grafted onto North American species' rootstock, a common practice due to their resistance to phylloxera, a root louse that eventually kills the vine. In the late 19th century, most of Europe's vineyards were devastated by the infestation, leading to widespread vine deaths and eventual replanting. Grafting is done in every wine-producing region in the world except in Argentina, the Canary Islands and Chile—the only places not yet exposed to the insect.
In the context of wine production, terroir is a concept that encompasses the varieties of grapes used, elevation and shape of the vineyard, type and chemistry of soil, climate and seasonal conditions, and the local yeast cultures. The range of possible combinations of these factors can result in great differences among wines, influencing the fermentation, finishing, and aging processes as well. Many wineries use growing and production methods that preserve or accentuate the aroma and taste influences of their unique terroir. However, flavor differences are less desirable for producers of mass-market table wine or other cheaper wines, where consistency takes precedence. Such producers try to minimize differences in sources of grapes through production techniques such as micro-oxygenation, tannin filtration, cross-flow filtration, thin-film evaporation,
and spinning cones.

Classification

Regulations govern the classification and sale of wine in many regions of the world. European wines tend to be classified by region, while non-European wines are most often classified by grape. Market recognition of particular regions has recently been leading to their increased prominence on non-European wine labels. Examples of recognized non-European locales include Napa Valley, Santa Clara Valley, Sonoma Valley, Anderson Valley, and Mendocino County in California; Willamette Valley and Rogue Valley in Oregon; Columbia Valley in Washington; Barossa Valley in South Australia; Hunter Valley in New South Wales; Luján de Cuyo in Argentina; Central Valley in Chile; Vale dos Vinhedos in Brazil; Hawke's Bay and Marlborough in New Zealand; and in Canada, the Okanagan Valley of British Columbia, and the Niagara Peninsula and Essex County regions of Ontario are the three largest producers.
Some blended wine names are marketing terms whose use is governed by trademark law rather than by specific wine laws. For example, Meritage is generally a Bordeaux-style blend of Cabernet Sauvignon and Merlot, but may also include Cabernet Franc, Petit Verdot, and Malbec. Commercial use of the term Meritage is allowed only via licensing agreements with the Meritage Association.

European classifications

France has various appellation systems based on the concept of terroir, with classifications ranging from Vin de Table at the bottom, through Vin de Pays and Appellation d'Origine Vin Délimité de Qualité Supérieure, up to Appellation d'Origine Contrôlée or similar, depending on the region. Portugal has developed a system resembling that of France and, in fact, pioneered this concept in 1756 with a royal charter creating the Demarcated Douro Region and regulating the production and trade of wine. Germany created a similar scheme in 2002, although it has not yet achieved the authority of the other countries' classification systems. Spain, Greece and Italy have classifications based on a dual system of region of origin and product quality.

Beyond Europe

—those made outside the traditional wine regions of Europe—are usually classified by grape rather than by terroir or region of origin, although there have been unofficial attempts to classify them by quality.
According to Canadian Food and Drug Regulations, wine in Canada is an alcoholic drink that is produced by the complete or partial alcoholic fermentation of fresh grapes, grape must, products derived solely from fresh grapes, or any combination of them. There are many materials added during the course of the manufacture, such as yeast, concentrated grape juice, dextrose, fructose, glucose or glucose solids, invert sugar, sugar, or aqueous solutions. Calcium sulphate in such quantity that the content of soluble sulphates in the finished wine shall not exceed 0.2 per cent weight by volume calculated as potassium sulphate. Calcium carbonate in such quantity that the content of tartaric acid in the finished wine shall not be less than 0.15 per cent weight by volume. Also, sulphurous acid, including salts thereof, in such quantity that its content in the finished wine shall not exceed 70 parts per million in the free state, or 350 parts per million in the combined state, calculated as sulphur dioxide. Caramel, amylase and pectinase at a maximum level of use consistent with good manufacturing practice. Brandy, fruit spirit or alcohol derived from the alcoholic fermentation of a food source distilled to not less than 94 per cent alcohol by volume. Prior to final filtration may be treated with a strongly acid cation exchange resin in the sodium ion form, or a weakly basic anion exchange resin in the hydroxyl ion form.

Vintages

In the United States, for a wine to be vintage-dated and labeled with a country of origin or American Viticultural Area, 95% of its volume must be from grapes harvested in that year. If a wine is not labeled with a country of origin or AVA the percentage requirement is lowered to 85%.
Vintage wines are generally bottled in a single batch so that each bottle will have a similar taste. Climate's impact on the character of a wine can be significant enough to cause different vintages from the same vineyard to vary dramatically in flavor and quality. Thus, vintage wines are produced to be individually characteristic of the particular vintage and to serve as the flagship wines of the producer. Superior vintages from reputable producers and regions will often command much higher prices than their average ones. Some vintage wines, are only made in better-than-average years.
For consistency, non-vintage wines can be blended from more than one vintage, which helps wine-makers sustain a reliable market image and maintain sales even in bad years. One recent study suggests that for the average wine drinker, the vintage year may not be as significant for perceived quality as had been thought, although wine connoisseurs continue to place great importance on it.

Tasting

is the sensory examination and evaluation of wine. Wines contain many chemical compounds similar or identical to those in fruits, vegetables, and spices. The sweetness of wine is determined by the amount of residual sugar in the wine after fermentation, relative to the acidity present in the wine. Dry wine, for example, has only a small amount of residual sugar. Some wine labels suggest opening the bottle and letting the wine "breathe" for a couple of hours before serving, while others recommend drinking it immediately. Decanting is a controversial subject among wine enthusiasts. In addition to aeration, decanting with a filter allows the removal of bitter sediments that may have formed in the wine. Sediment is more common in older bottles, but aeration may benefit younger wines.
During aeration, a younger wine's exposure to air often "relaxes" the drink, making it smoother and better integrated in aroma, texture, and flavor. Older wines generally fade with extended aeration. Despite these general rules, breathing does not necessarily benefit all wines. Wine may be tasted as soon as the bottle is opened to determine how long it should be aerated, if at all. When tasting wine, individual flavors may also be detected, due to the complex mix of organic molecules that grape juice and wine can contain. Experienced tasters can distinguish between flavors characteristic of a specific grape and flavors that result from other factors in wine-making. Typical intentional flavor elements in wine—chocolate, vanilla, or coffee—are those imparted by aging in oak casks rather than the grape itself.
Vertical and horizontal tasting involves a range of vintages within the same grape and vineyard, or the latter in which there is one vintage from multiple vineyards. "Banana" flavors are the product of yeast metabolism, as are spoilage aromas such as "medicinal" or "Band-Aid", "spicy" or "smoky", and rotten egg. Some varieties can also exhibit a mineral flavor due to the presence of water-soluble salts as a result of limestone's presence in the vineyard's soil. Wine aroma comes from volatile compounds released into the air. Vaporization of these compounds can be accelerated by twirling the wine glass or serving at room temperature. Many drinkers prefer to chill red wines that are already highly aromatic, like Chinon and Beaujolais.
The ideal temperature for serving a particular wine is a matter of debate by wine enthusiasts and sommeliers, but some broad guidelines have emerged that will generally enhance the experience of tasting certain common wines. A white wine should foster a sense of coolness, achieved by serving at "cellar temperature". Light red wines drunk young should also be brought to the table at this temperature, where they will quickly rise a few degrees. Red wines are generally perceived best when served chambré. However, this does not mean the temperature of the dining room—often around —but rather the coolest room in the house and, therefore, always slightly cooler than the dining room itself. Pinot noir should be brought to the table for serving at and will reach its full bouquet at. Cabernet Sauvignon, zinfandel, and Rhone varieties should be served at and allowed to warm on the table to for best aroma.

Collecting

Outstanding vintages from the best vineyards may sell for thousands of dollars per bottle, though the broader term "fine wine" covers those typically retailing in excess of US$30–50. "Investment wines" are considered by some to be Veblen goods: those for which demand increases rather than decreases as their prices rise.
Particular selections have higher value, such as "Verticals", in which a range of vintages of a specific grape and vineyard, are offered. The most notable was a Château d'Yquem 135 year vertical containing every vintage from 1860 to 2003 sold for $1.5 million.
The most common wines purchased for investment include those from Bordeaux and Burgundy; cult wines from Europe and elsewhere; and vintage port. Characteristics of highly collectible wines include:
  1. A proven track record of holding well over time
  2. A drinking-window plateau that is many years long
  3. A consensus among experts as to the quality of the wines
  4. Rigorous production methods at every stage, including grape selection and appropriate barrel aging
Investment in fine wine has attracted those who take advantage of their victims' relative ignorance of this wine market sector. Such wine fraudsters often profit by charging excessively high prices for off-vintage or lower-status wines from well-known wine regions, while claiming that they are offering a sound investment unaffected by economic cycles. As with any investment, thorough research is essential to making an informed decision.

Consumption

Wine-consumption data from a list of countries by alcohol consumption measured in liters of pure ethyl alcohol consumed per capita in a given year, according to the most recent data from the World Health Organization. The methodology includes persons 15 years of age or older. About 40% of individuals above the legal drinking age consider themselves "wine drinkers", which is higher than all other alcoholic beverages combined and those who do not drink at all.

Culinary uses

Wine is a popular and important drink that accompanies and enhances a wide range of cuisines, from the simple and traditional stews to the most sophisticated and complex haute cuisines. Wine is often served with dinner. Sweet dessert wines may be served with the dessert course. In fine restaurants in Western countries, wine typically accompanies dinner. At a restaurant, patrons are helped to make good food-wine pairings by the restaurant's sommelier or wine waiter. Individuals dining at home may use wine guides to help make food–wine pairings. Wine is also drunk without the accompaniment of a meal in wine bars or with a selection of cheeses. Wines are also used as a theme for organizing various events such as festivals around the world; the city of Kuopio in North Savonia, Finland is known for its annual Kuopio Wine Festivals.
Wine is important in cuisine not just for its value as a drink, but as a flavor agent, primarily in stocks and braising, since its acidity lends balance to rich savory or sweet dishes. Wine sauce is an example of a culinary sauce that uses wine as a primary ingredient. Natural wines may exhibit a broad range of alcohol content, from below 9% to above 16% ABV, with most wines being in the 12.5–14.5% range. Fortified wines may contain 20% alcohol or more.

Religious significance

Ancient religions

The use of wine in ancient Near Eastern and Ancient Egyptian religious ceremonies was common. Libations often included wine, and the religious mysteries of Dionysus used wine as a sacramental entheogen to induce a mind-altering state.

Judaism

Wine is an integral part of Jewish laws and traditions. The Kiddush is a blessing recited over wine or grape juice to sanctify the Shabbat. On Pesach during the Seder, it is a Rabbinic obligation of adults to drink four cups of wine. In the Tabernacle and in the Temple in Jerusalem, the libation of wine was part of the sacrificial service. Note that this does not mean that wine is a symbol of blood, a common misconception that contributes to the Christian beliefs of the blood libel.
"It has been one of history's cruel ironies that the blood libel—accusations against Jews using the blood of murdered gentile children for the making of wine and matzot—became the false pretext for numerous pogroms. And due to the danger, those who live in a place where blood libels occur are halachically exempted from using red wine, lest it be seized as "evidence" against them."

Christianity

In Christianity, wine is used in a sacred rite called the Eucharist, which originates in the Gospel account of the Last Supper describing Jesus sharing bread and wine with his disciples and commanding them to "do this in remembrance of me." Beliefs about the nature of the Eucharist vary among denominations.
While some Christians consider the use of wine from the grape as essential for the validity of the sacrament, many Protestants also allow pasteurized grape juice as a substitute. Wine was used in Eucharistic rites by all Protestant groups until an alternative arose in the late 19th century. Methodist dentist and prohibitionist Thomas Bramwell Welch applied new pasteurization techniques to stop the natural fermentation process of grape juice. Some Christians who were part of the growing temperance movement pressed for a switch from wine to grape juice, and the substitution spread quickly over much of the United States, as well as to other countries to a lesser degree. There remains an ongoing debate between some American Protestant denominations as to whether wine can and should be used for the Eucharist or allowed as an ordinary drink, with Catholics and some mainline Protestants allowing wine drinking in moderation, and some conservative Protestant groups opposing consumption of alcohol altogether.
The earliest viticulture tradition in the Southwestern United States starts with sacramental wine, beginning in the 1600s, with Christian friars and monks producing New Mexico wine.

Islam

Alcoholic drinks, including wine, are forbidden under most interpretations of Islamic law. In many Muslim countries, possession or consumption of alcoholic drinks carry legal penalties. Iran had previously had a thriving wine industry that disappeared after the Islamic Revolution in 1979. In Greater Persia, mey was a central theme of poetry for more than a thousand years, long before the advent of Islam. Some Alevi sects – one of the two main branches of Islam in Turkey – use wine in their religious services.
Certain exceptions to the ban on alcohol apply. Alcohol derived from a source other than the grape and the date is allowed in "very small quantities" under the Sunni Hanafi madhab, for specific purposes, where the goal is not intoxication. However, modern Hanafi scholars regard alcohol consumption as totally forbidden.

Health effects

Short-term effects

Wine contains ethyl alcohol, the same chemical that is present in beer and distilled spirits and as such, wine consumption has short-term psychological and physiological effects on the user. Different concentrations of alcohol in the human body have different effects on a person. The effects of alcohol depend on the amount an individual has drunk, the percentage of alcohol in the wine and the timespan that the consumption took place, the amount of food eaten and whether an individual has taken other prescription, over-the-counter or street drugs, among other factors. Drinking enough to cause a blood alcohol concentration of 0.03%-0.12% typically causes an overall improvement in mood and possible euphoria, increased self-confidence and sociability, decreased anxiety, a flushed, red appearance in the face and impaired judgment and fine muscle coordination. A BAC of 0.09% to 0.25% causes lethargy, sedation, balance problems and blurred vision. A BAC from 0.18% to 0.30% causes profound confusion, impaired speech, staggering, dizziness and vomiting. A BAC from 0.25% to 0.40% causes stupor, unconsciousness, anterograde amnesia, vomiting, and death may occur due to inhalation of vomit while unconscious and respiratory depression. A BAC from 0.35% to 0.80% causes a coma, life-threatening respiratory depression and possibly fatal alcohol poisoning. As with all alcoholic drinks, drinking while driving, operating an aircraft or heavy machinery increases the risk of an accident; many countries have penalties against drunk driving.
Wines can trigger positive emotions in a short period of time, such as feelings of relaxation and comfort. The context and quality of wine can affect the mood and emotions, too.

Long-term effects

The main active ingredient of wine is alcohol, and therefore, the health effects of alcohol apply to wine. A 2016 systematic review and meta-analysis found that moderate ethanol consumption brought no mortality benefit compared with lifetime abstention from ethanol consumption. A systematic analysis of data from the Global Burden of Disease study found that consumption of ethanol increases the risk of cancer and increases the risk of all-cause mortality, and that the level of ethanol consumption that minimizes disease is zero consumption. Some studies have concluded that drinking small quantities of alcohol is associated with a decreased risk of heart disease, stroke, diabetes mellitus, and early death. Drinking more than this amount actually increases the risk of heart disease, high blood pressure, atrial fibrillation, and stroke. Some of these studies lumped former ethanol drinkers and life-long abstainers into a single group of nondrinkers, hiding the health benefits of life-long abstention from ethanol. Risk is greater in younger people due to binge drinking which may result in violence or accidents. About 3.3 million deaths are believed to be due to alcohol each year.
Alcoholism is a broad term for any drinking of alcohol that results in problems. It was previously divided into two types: alcohol abuse and alcohol dependence. In a medical context, alcoholism is said to exist when two or more of the following conditions is present: a person drinks large amounts over a long time period, has difficulty cutting down, acquiring and drinking alcohol takes up a great deal of time, alcohol is strongly desired, usage results in not fulfilling responsibilities, usage results in social problems, usage results in health problems, usage results in risky situations, withdrawal occurs when stopping, and alcohol tolerance has occurred with use. Alcoholism reduces a person's life expectancy by around ten years and alcohol use is the third leading cause of early death in the United States. No professional medical association recommends that people who are nondrinkers should start drinking wine.
Excessive consumption of alcohol can cause liver cirrhosis and alcoholism. The American Heart Association "cautions people NOT to start drinking... if they do not already drink alcohol. Consult your doctor on the benefits and risks of consuming alcohol in moderation."
Population studies exhibit a J-curve correlation between wine consumption and rates of heart disease: heavy drinkers have an elevated rate, while people who drink small amount have a lower rate than non-drinkers. Studies have also found that moderate consumption of other alcoholic drinks is correlated with decreased mortality from cardiovascular causes, although the association is stronger for wine. Additionally, some studies have found a greater correlation of health benefits with red than white wine, though other studies have found no difference. Red wine contains more polyphenols than white wine, and these could be protective against cardiovascular disease.
Although red wine contains the chemical resveratrol and there is tentative evidence it may improve heart health, the evidence is unclear for those at high risk as of 2013. Grape skins naturally produce resveratrol in response to fungal infection, including exposure to yeast during fermentation. White wine generally contains lower levels of the chemical as it has minimal contact with grape skins during this process.

Forgery and manipulation

Incidents of fraud, such as mislabeling the origin or quality of wines, have resulted in regulations on labeling. "Wine scandals" that have received media attention include:
Most wines are sold in glass bottles and sealed with corks. An increasing number of wine producers have been using alternative closures such as screwcaps and synthetic plastic "corks". Although alternative closures are less expensive and prevent cork taint, they have been blamed for such problems as excessive reduction.
Some wines are packaged in thick plastic bags within corrugated fiberboard boxes, and are called "box wines", or "cask wine". Tucked inside the package is a tap affixed to the bag in box, or bladder, that is later extended by the consumer for serving the contents. Box wine can stay acceptably fresh for up to a month after opening because the bladder collapses as wine is dispensed, limiting contact with air and, thus, slowing the rate of oxidation. In contrast, bottled wine oxidizes more rapidly after opening because of the increasing ratio of air to wine as the contents are dispensed; it can degrade considerably in a few days. Cans are one of the fastest-growing forms of alternative wine packaging on the market.
Environmental considerations of wine packaging reveal benefits and drawbacks of both bottled and box wines. The glass used to make bottles is a nontoxic, naturally occurring substance that is completely recyclable, whereas the plastics used for box-wine containers are typically much less environmentally friendly. However, wine-bottle manufacturers have been cited for Clean Air Act violations. A New York Times editorial suggested that box wine, being lighter in package weight, has a reduced carbon footprint from its distribution; however, box-wine plastics, even though possibly recyclable, can be more labor-intensive to process than glass bottles. In addition, while a wine box is recyclable, its plastic bladder most likely is not. Some people are drawn to canned wine due to its portability and recyclable packaging.
Some wine is sold in stainless steel kegs and is referred to as wine on tap.

Storage

s, or wine rooms, if they are above-ground, are places designed specifically for the storage and aging of wine. Fine restaurants and some private homes have wine cellars. In an active wine cellar, temperature and humidity are maintained by a climate-control system. Passive wine cellars are not climate-controlled, and so must be carefully located. Because wine is a natural, perishable food product, all types—including red, white, sparkling, and fortified—can spoil when exposed to heat, light, vibration or fluctuations in temperature and humidity. When properly stored, wines can maintain their quality and in some cases improve in aroma, flavor, and complexity as they age. Some wine experts contend that the optimal temperature for aging wine is, others.
Wine refrigerators offer a smaller alternative to wine cellars and are available in capacities ranging from small, 16-bottle units to furniture-quality pieces that can contain 400 bottles. Wine refrigerators are not ideal for aging, but rather serve to chill wine to the proper temperature for drinking. These refrigerators keep the humidity low, below the optimal humidity of 50% to 70%. Lower humidity levels can dry out corks over time, allowing oxygen to enter the bottle, which reduces the wine's quality through oxidation. While some types of alcohol are sometimes stored in freezer, such as vodka, it is not possible to safely freeze wine in the bottle, as there is insufficient room for it to expand as it freezes and the bottle will usually crack. Certain shapes of bottle may allow the cork to be pushed out by the ice, but if the bottle is frozen on its side, the wine in the narrower neck will invariably freeze first, preventing this.

Professions

There are a large number of occupations and professions that are part of the wine industry, ranging from the individuals who grow the grapes, prepare the wine, bottle it, sell it, assess it, market it and finally make recommendations to clients and serve the wine.
