49-405: There was no large-scale commercial plantation of Arbutus unedo until the 21st century and in the past the arbutus berries were mainly collected by local farmers, by hand and processed privately. Therefore, good Aguardente de Medronhos was not easily found in supermarkets but instead bought mostly directly from these farmers. Very few farmers had a license for distillation, but they were tolerated by

98-860: A cocktail . In an undiluted form, distilled beverages are often slightly sweet and bitter and typically impart a burning mouthfeel with an odor derived from the alcohol and the production and aging processes; the exact flavor varies between different varieties of liquor and the different impurities they impart. Rapid consumption of a large amount of liquor can cause severe alcohol intoxication or alcohol poisoning , which can be fatal either due to acute biochemical damage to vital organs (e.g. alcoholic hepatitis and pancreatitis ), or due to trauma (e.g. falls or motor vehicle accidents ) caused by alcohol-induced delirium . Consistent consumption of liquor over time correlates with higher mortality and other harmful health effects, even when compared to other alcoholic beverages. The term "spirit" (singular and used without

147-720: A percentage of total mass . The alc/vol value of a beverage is always higher than the ABW. Because ABW measures the proportion of the drink's mass which is alcohol, while alc/vol is the proportion of the drink's volume which is alcohol, the two values are in the same proportion as the drink's density is with the density of alcohol. Therefore, one can use the following equation to convert between ABV and ABW: ABV = ABW × density of beverage density of alcohol {\displaystyle {\text{ABV}}={\text{ABW}}\times {\frac {\text{density of beverage}}{\text{density of alcohol}}}} At relatively low alc/vol,

196-473: A 50% v/v ethanol solution, 50 mL of ethanol and 50 mL of water could be mixed but the resulting volume of solution will measure less than 100 mL due to the change of volume on mixing, and will contain a higher concentration of ethanol. The difference is not large, with the maximum difference being less than 2.5%, and less than 0.5% difference for concentrations under 20%. Some drinks have requirements of alcoholic content in order to be certified as

245-415: A certain alcohol brand or label. Low-alcohol beers (<0.5) are considered in some countries such as Iran as permitted (or "halal" under Muslim vocabulary) despite alcohol being banned. However, the level of alcohol-free beers is typically the lowest commercially sold 0.05. It is near impossible for a healthy person to become intoxicated drinking low-alcohol drinks. The low concentration severely limits

294-568: A concentration over 50%. Beer and wine , which are not distilled, typically have a maximum alcohol content of about 15% ABV, as most yeasts cannot metabolize when the concentration of alcohol is above this level; as a consequence, fermentation ceases at that point. The origin of liquor and its close relative liquid is the Latin verb liquere , meaning 'to be fluid'. According to the Oxford English Dictionary ( OED ), an early use of

343-405: A given year in a country. In Europe, spirits (especially vodka) are more popular in the north and east of the continent. Distilled spirits contain ethyl alcohol , the same chemical that is present in beer and wine , and as such, spirit consumption has short-term psychological and physiological effects on the user. Different concentrations of alcohol in the human body have different effects on

392-457: A halt as the alcohol produced becomes too concentrated for the yeast to tolerate, defining an upper limit of alc/vol for non-distilled alcoholic drinks. The typical tolerance for beer yeasts is at 8–12%, while wine yeasts typically range from 14–18%, with speciality ones reaching 20% alc/vol. Any higher would require distillation, producing liquor . Details about typical amounts of alcohol contained in various beverages can be found in

441-409: A number of Latin works, and by the end of the thirteenth century, it had become a widely known substance among Western European chemists. Its medicinal properties were studied by Arnald of Villanova (1240–1311 CE) and John of Rupescissa (c. 1310–1366), the latter of whom regarded it as a life-preserving substance able to prevent all diseases (the aqua vitae or "water of life", also called by John

490-531: A person. The effects of alcohol depend on the amount an individual has drunk, the percentage of alcohol in the spirits and the timespan over which the consumption took place. The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), to stupor , unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses. Cell membranes are highly permeable to alcohol , so once it

539-413: A slight increase in total volume, whereas the mixing of two solutions above 24% causes a decrease in volume. The phenomenon of volume changes due to mixing dissimilar solutions is called " partial molar volume ". Water and ethanol are both polar solvents. When water is added to ethanol, the smaller water molecules are attracted to the ethanol's hydroxyl group, and each molecule alters the polarity field of

588-511: A trend in the United States following the microbrewing and craft beer movement in the last decades of the 20th century. Liquor that contains 40% ABV (80 US proof ) will catch fire if heated to about 26 °C (79 °F) and if an ignition source is applied to it. This temperature is called its flash point . The flash point of pure alcohol is 16.6 °C (61.9 °F), less than average room temperature. The flammability of liquor

637-441: Is 1.05 times that of water, it has a specific gravity of 1.05. In UK brewing usage, it is customary to regard the reference value for water to be 1000, so the specific gravity of the same example beer would be quoted as 1050. The formulas here assume that the former definition is used for specific gravity. During ethanol fermentation the yeast converts one mole of sugar into two moles of alcohol. A general formula for calculating

686-421: Is also prohibited in some local jurisdictions). Some countries and sub-national jurisdictions limit or prohibit the sale of certain high-percentage alcohol, commonly known as neutral spirit . Due to its flammability (see below) alcoholic beverages with an alcohol content above 70% by volume are not permitted to be transported in aircraft. Microdistilling (also known as craft distilling) began to re-emerge as

735-409: Is an alcoholic beverage that has been produced: Spirit drinks must contain at least 15% ABV (except in the case of egg liqueur such as Advocaat , which must contain a minimum of 14% ABV). Regulation makes a difference between "ethyl alcohol of agricultural origin" and a "distillate of agricultural origin". Distillate of agricultural origin is defined as an alcoholic liquid that is the result of

784-411: Is applied in the cooking technique flambé . The flash points of alcohol concentrations from 10% to 96% by weight are: Liquor can be served: The World Health Organization (WHO) measures and publishes alcohol consumption patterns in different countries. The WHO measures alcohol consumed by persons 15 years of age or older and reports it on the basis of liters of pure alcohol consumed per capita in

833-602: Is in the bloodstream, it can diffuse into nearly every cell in the body. Alcohol can greatly exacerbate sleep problems. During abstinence , residual disruptions in sleep regularity and sleep patterns are the greatest predictors of relapse . Drinking more than 1–2 drinks a day increases the risk of heart disease, high blood pressure , atrial fibrillation , and stroke . The risk is greater in younger people due to binge drinking , which may result in violence or accidents. About 3.3 million deaths (5.9% of all deaths) are due to alcohol each year. Unlike wine and perhaps beer, there

882-462: Is no evidence for a J-shaped health effect for the consumption of distilled alcohol. Long-term use can lead to an alcohol use disorder , an increased risk of developing physical dependence . cardiovascular disease and several types of cancer . Alcoholism , also known as "alcohol use disorder", is a broad term for any drinking of alcohol that results in problems. Alcoholism reduces a person's life expectancy by around ten years and alcohol use

931-594: Is often referred to as degrees Gay-Lussac (after the French chemist Joseph Louis Gay-Lussac ), although there is a slight difference since the Gay-Lussac convention uses the International Standard Atmosphere value for temperature, 15 °C (59 °F). Mixing two solutions of alcohol of different strengths usually causes a change in volume. Mixing pure water with a solution less than 24% by mass causes

980-636: Is sugar by weight and SG is relative density. SG can be measured using an hydrometer and Brix can be calculated from SG. One of the accurate formulas for calculating Brix from SG is: By substituting Brix in the SBV formula above, we get a formula for calculating SBV from SG only: The general calculation steps involves calculation of SBV at the start and the end of fermentation: Advanced formula derived from Carl Balling empirical formulas. The formula compensates for changes in SG with changes in alcohol concentration and for

1029-454: Is the mass of the ethanol divided by its density at 20 °C (68 °F), which is 0.78945 g/mL (0.82353 oz/US fl oz; 0.79122 oz/imp fl oz; 0.45633 oz/cu in). The alc/vol standard is used worldwide. The International Organization of Legal Metrology has tables of density of water–ethanol mixtures at different concentrations and temperatures. In some countries, e.g. France , alcohol by volume

1078-1225: Is the specific gravity when fermentation ends, Plato start is the sugar by weight when fermentation begins, Plato final is the sugar by weight when fermentation ends. Brix can be used insted of Plato as they are nearly identical. The simplest method for wine has been described by English author Cyril Berry : ABV ≈ 136 × ( Starting SG − Final SG ) {\displaystyle {\text{ABV}}\approx 136\times \left({\text{Starting SG}}-{\text{Final SG}}\right)} One calculation for beer is: ABV ≈ 131 × ( Starting SG − Final SG ) {\displaystyle {\text{ABV}}\approx 131\times \left({\text{Starting SG}}-{\text{Final SG}}\right)} For higher ABV above 6% many brewers use this formula: alc/vol ≈ 105 0.79 × ( Starting SG − Final SG Final SG ) {\displaystyle {\text{alc/vol}}\approx {\frac {105}{0.79}}\times \left({\frac {{\text{Starting SG}}-{\text{Final SG}}}{\text{Final SG}}}\right)} Another way of specifying

1127-478: Is the third-leading cause of early death in the United States. Consumption of alcohol in any quantity can cause cancer . Alcohol causes breast cancer , colorectal cancer , esophageal cancer , liver cancer , and head-and-neck cancers . The more alcohol is consumed, the higher the cancer risk. A survey of high school students in Alstahaug, Nordland county, revealed that adolescents consume alcohol at rates above

1176-400: Is used to measure the change in specific gravity (SG) of the solution before and after fermentation. The volume of alcohol in the solution can then be estimated. There are a number of empirical formulae which brewers and winemakers use to estimate the alcohol content of the liquor made. Specific gravity is the density of a liquid relative to that of water, i.e., if the density of the liquid

1225-576: The quintessence of wine). In China, archaeological evidence indicates that the true distillation of alcohol began during the 12th century Jin or Southern Song dynasties. A still has been found at an archaeological site in Qinglong, Hebei , dating to the 12th century. In India, the true distillation of alcohol was introduced from the Middle East and was in wide use in the Delhi Sultanate by

1274-587: The Jin (12th–13th centuries) and Southern Song (10th–13th centuries) dynasties according to archaeological evidence. Freeze distillation involves freezing the alcoholic beverage and then removing the ice. The freezing technique had limitations in geography and implementation limiting how widely this method was put to use. The flammable nature of the exhalations of wine was already known to ancient natural philosophers such as Aristotle (384–322 BCE), Theophrastus ( c.  371  – c.  287 BCE ), and Pliny

1323-654: The United Kingdom , proof is 1.75 times the number (expressed as a percentage). For example, 40% alc/vol is 80 proof in the US and 70 proof in the UK. However, since 1980, alcohol proof in the UK has been replaced by alc/vol as a measure of alcohol content, avoiding confusion between the UK and US proof standards. In the United States, Arkansas , Kansas , Mississippi , South Carolina , and Tennessee regulate and tax alcoholic beverages according to alcohol by weight ( ABW ), expressed as

1372-519: The distillation of grains , fruits , vegetables , or sugar that have already gone through alcoholic fermentation . Other terms for liquor include spirit , spirituous liquor or hard liquor . While the word liquor ordinarily refers to distilled alcoholic spirits rather than beverages produced by fermentation alone, it can sometimes be used more broadly to refer to any alcoholic beverage (or even non-alcoholic products of distillation or various other liquids). The distillation process concentrates

1421-565: The 14th century. The works of Taddeo Alderotti (1223–1296) describe a method for concentrating alcohol involving repeated fractional distillation through a water-cooled still, by which an alcohol purity of 90% could be obtained. In 1437, "burned water" ( brandy ) was mentioned in the records of the County of Katzenelnbogen in Germany. It is legal to distill beverage alcohol as a hobby for personal use in some countries, including New Zealand and

1470-552: The 1st century. Distilled water was described in the 2nd century AD by Alexander of Aphrodisias . Alchemists in Roman Egypt were using a distillation alembic or still device in the 3rd century. Distillation was known in the ancient Indian subcontinent , evident from baked clay retorts and receivers found at Taxila and Charsadda in Pakistan and Rang Mahal in India dating to

1519-460: The Elder (23/24–79 CE). This did not immediately lead to the isolation of alcohol, however, despite the development of more advanced distillation techniques in second- and third-century Roman Egypt . An important recognition, first found in one of the writings attributed to Jābir ibn Ḥayyān (ninth century CE), was that by adding salt to boiling wine, which increases the wine's relative volatility ,

1568-741: The Gin category but any gin cannot be considered as London gin). Spirit drinks that are not produced within the EU, such as tequila or baijiu , are not listed in the 44 categories. Early evidence of distillation comes from Akkadian tablets dated c.  1200 BC describing perfumery operations, providing textual evidence that an early, primitive form of distillation was known to the Babylonians of ancient Mesopotamia . Early evidence of distillation also comes from alchemists working in Alexandria , Roman Egypt , in

1617-564: The Netherlands. In many others including the United States , it is illegal to distill beverage alcohol without a license, and the licensing process is too arduous for hobbyist-scale production. In some parts of the U.S., it is also illegal to sell a still without a license. Nonetheless, all states allow unlicensed individuals to make their own beer , and some also allow unlicensed individuals to make their own wine (although making beer and wine

1666-476: The additional term "drink") refers to liquor that should not contain added sugar and is usually 35–40% alcohol by volume (ABV). Fruit brandy , for example, is also known as 'fruit spirit'. Liquor bottled with added sugar and flavorings, such as Grand Marnier , amaretto , and American schnapps , are known instead as liqueurs . Liquor generally has an alcohol concentration higher than 30% when bottled, and before being diluted for bottling, it typically has

1715-470: The amount of alcohol content is alcohol proof , which in the United States is twice the alcohol-by-volume (alc/vol) number. This may lead to confusion over similar products bought in varying regions that have different names on country-specific labels. For example, Stroh rum that is 80% ABV is advertised and labeled as Stroh 80 when sold in Europe, but is named Stroh 160 when sold in the United States. In

1764-538: The articles about them. (most juices do not have alcohol but orange or grape [the highest here] may have some from early fermentation) Under 2.5% in Finland, and 2.25% in Sweden, however. During the production of wine and beer, yeast is added to a sugary solution. During fermentation, the yeasts consume the sugars and produce alcohol. The density of sugar in water is greater than the density of alcohol in water. A hydrometer

1813-407: The authorities to keep this traditional Portuguese specialty alive. A commercial derivative, sweetened with honey and flavoured with herbs, is sold under the brand names Brandymel and Dom Cristina. Aguardente de Medronhos is also known as 'firewater' to non-Portuguese speakers. It is a rough translation from água ardente , which is Portuguese for burning water . The spirit obtains this name from

1862-438: The distillation, after alcoholic fermentation, of agricultural products which does not have the properties of ethyl alcohol and which retain the aroma and taste of the raw materials used. Annex 1 to the regulation lists 44 categories of spirit drinks and their legal requirements. Some spirit drinks can fall into more than one category. Specific production requirements distinguish one category from another (London gin falls into

1911-573: The early centuries of the Common Era . Frank Raymond Allchin says these terracotta distill tubes were "made to imitate bamboo". These " Gandhara stills" were capable of producing only very weak liquor, as there was no efficient means of collecting the vapors at low heat. Distillation in China could have begun during the Eastern Han dynasty (1st–2nd centuries), but the distillation of beverages began in

1960-584: The fact that not all sugar is converted into alcohol. All values are measured at 20 degree C. A B V = − 118772 × SG final × ( Plato start − Plato final ) ( Plato start − 193.765 ) × ( Plato start + 1220 ) {\displaystyle ABV={\frac {-118772\times {\text{SG final}}\times ({\text{Plato start}}-{\text{Plato final}})}{({\text{Plato start}}-193.765)\times ({\text{Plato start}}+1220)}}} where SG final

2009-525: The flammability of the resulting vapors may be enhanced. The distillation of wine is attested in Arabic works attributed to al-Kindī (c. 801–873 CE) and to al-Fārābī (c. 872–950), and in the 28th book of al-Zahrāwī 's (Latin: Abulcasis, 936–1013) Kitāb al-Taṣrīf (later translated into Latin as Liber servatoris ). In the twelfth century, recipes for the production of aqua ardens ("burning water", i.e., alcohol) by distilling wine with salt started to appear in

2058-538: The hot sensation as the consumed beverage travels down the throat and is felt through the sinuses. The alcohol content of the beverage can vary; however, many bottles of Aguardente de Medronhos contain around 48% alcohol by volume. The beverage is consumed in shot-glass sized portions. This distilled beverage –related article is a stub . You can help Misplaced Pages by expanding it . Distilled beverage Liquor ( / ˈ l ɪ k ər / LIK -ər ) or distilled beverages are alcoholic drinks produced by

2107-488: The liquid to increase its alcohol by volume . As liquors contain significantly more alcohol ( ethanol ) than other alcoholic drinks, they are considered "harder". In North America , the term hard liquor is sometimes used to distinguish distilled alcoholic drinks from non-distilled ones, whereas the term spirits is more commonly used in the United Kingdom . Some examples of liquors include vodka , rum , gin and tequila . Liquors are often aged in barrels , such as for

2156-596: The national average, with home-made liquor being prevalent and easily accessible, highlighting an urgent need for preventive measures. Alcohol by volume Alcohol by volume (abbreviated as alc/vol or ABV ) is a standard measure of the volume of alcohol contained in a given volume of an alcoholic beverage , expressed as a volume percent . It is defined as the number of millilitres (mL) of pure ethanol present in 100 mL (3.5 imp fl oz; 3.4 US fl oz) of solution at 20 °C (68 °F). The number of millilitres of pure ethanol

2205-557: The other. The attraction allows closer spacing between molecules than is usually found in non-polar mixtures. Thus, alc/vol is not the same as volume fraction expressed as a percentage. Volume fraction, which is widely used in chemistry (commonly denoted as v/v), is defined as the volume of a particular component divided by the sum of all components in the mixture when they are measured separately. For example, to make 100 mL of 50% alc/vol ethanol solution, water would be added to 50 mL of ethanol to make up exactly 100 mL. Whereas to make

2254-411: The production of brandy and whiskey , or are infused with flavorings to form flavored liquors , such as absinthe . Like other alcoholic drinks, liquor is typically consumed for the psychoactive effects of alcohol. Liquor may be consumed on its own (i.e. " neat "), typically in amounts of around 50 millilitres (1.7 US fluid ounces) per served drink; or frequently mixed with other ingredients to form

2303-438: The rate of intake, which is easily dispatched by human metabolism. Quickly drinking 1.5 L of 0.4% alc/vol beer in an hour resulted in a maximum of 0.0056% BAC in a study of German volunteers. Healthy human kidneys can only excrete 0.8–1.0 L of water per hour, making water intoxication likely to set in before any alcoholic intoxication. The process of ethanol fermentation will slow down and eventually come to

2352-423: The resulting alcohol concentration by volume can be written: where SBV fermented is sugar by volume (g/dL) converted to alcohol during fermentation and GECF is the glucose-ethanol conversion factor: where 46.069 is the molar mass of ethanol and 180.156 is the molar mass of glucose and fructose . Sugar by volume is calculated at the beginning (start) and at the end (final) of the fermentation: where Brix

2401-610: The word in the English language, meaning simply "a liquid", can be dated to 1225. The first use documented in the OED defined as "a liquid for drinking" occurred in the 14th century. Its use as a term for "an intoxicating alcoholic drink" appeared in the 16th century. In accordance with the regulation (EU) 2019/787 of the European Parliament and of the Council of April 17, 2019, a spirit drink
