Alcohol measurements are units of measurement for determining amounts of beverage alcohol. Alcohol concentration in beverages is commonly expressed as alcohol by volume (ABV), ranging from less than 0.1% in fruit juices to up to 98% in rare cases of spirits. A "standard drink" is used globally to quantify alcohol intake, though its definition varies widely by country. Serving sizes of alcoholic beverages also vary by country.
typically 30%-40% (range is from 15% to, in some rare cases, up to 98%)
The concentration of alcohol in a beverage is usually stated as the percentage of alcohol by volume (ABV, the number of milliliters (ml) of pure ethanol in 100 ml of beverage) or as proof. In the United States, proof is twice the percentage of alcohol by volume at 60 degrees Fahrenheit (e.g. 80 proof = 40% ABV). Degrees proof were formerly used in the United Kingdom, where 100 degrees proof was equivalent to 57.1% ABV. Historically, this was the most dilute spirit that would sustain the combustion of gunpowder.
Ordinary distillation cannot produce alcohol of more than 95.6% by weight, which is about 97.2% ABV (194.4 proof) because at that point alcohol is an azeotrope with water. A spirit which contains a very high level of alcohol and does not contain any added flavoring is commonly called a neutral spirit. Generally, any distilled alcoholic beverage of 170 US proof or higher is considered to be a neutral spirit.[2]
Most yeasts cannot reproduce when the concentration of alcohol is higher than about 18%, so that is the practical limit for the strength of fermented drinks such as wine, beer, and sake. However, some strains of yeast have been developed that can reproduce in solutions of up to 25% ABV.[3]
A standard drink is a notional drink that contains a specified amount of pure alcohol. The standard drink is used in many countries to quantify alcohol intake. It is usually expressed as a measure of beer, wine, or spirits. One standard drink always contains the same amount of alcohol regardless of serving size or the type of alcoholic beverage. The standard drink varies significantly from country to country. For example, it is 7.62 ml (6 grams) of alcohol in Austria, but in Japan it is 25 ml (19.75 grams):
In the United Kingdom, there is a system of units of alcohol which serves as a guideline for alcohol consumption. A single unit of alcohol is defined as 10 ml. The number of units present in a typical drink is sometimes printed on bottles. The system is intended as an aid to people who are regulating the amount of alcohol they drink; it is not used to determine serving sizes.
In the United States, the standard drink contains 0.6 US fluid ounces (18 ml) of alcohol. This is approximately the amount of alcohol in a 12-US-fluid-ounce (350 ml) glass of beer, a 5-US-fluid-ounce (150 ml) glass of wine, or a 1.5-US-fluid-ounce (44 ml) glass of a 40% ABV (80 US proof) spirit.
A standard drink of 10g alcohol is used in the WHO AUDIT (Alcohol Use Disorders Identification Test)'s questionnaire form example,[4] and has been adopted by more countries than any other amount.[5] 10 grams is equivalent to 12.7 millilitres.
1⁄3 of an Imperial pint. Short for Nipperkin. Strong ale and Barley wine were usually bottled in nips[8] Metric measurement glasses and containers usually round up to a metric half pint of 200 mL (7 imp oz).
1⁄2 Imperial pint. A gill of beer was a customary measure equal to half an imperial pint (10 imperial fluid ounces or 280 millilitres) used in rural parts of England.[9] It is a holdover from when spirits, wines and brandies, ale, and beer all had different standard measures of capacity. An Ale Gill (based on the Ale gallon) and a Beer Gill (based on the Beer gallon) were different sizes until standardized as Ale / Beer gallons in 1688, Beer gallons in 1803, and Imperial gallons in 1824.

bottle (US)
355 mL
12 US fl oz
12.49 imp oz
3⁄4 US pint. American breweries fluctuated between 11 and 13 ounces before gradually standardizing on a median 12 ounces after World War II. The American Twelfth (102⁄3 US oz [315 mL], or 1⁄12 of a US gallon), American Commercial Pint (12.8 US fl oz [379 mL], or 1⁄10 of a US gallon) / British Reputed Pint (131⁄3 imp oz [379 mL], or 1⁄12 an Imperial gallon), and the Canadian "stubby" bottle (12 imp oz [341 mL]) may have been factors.
Stubbie (AUS)
375mL
12.68 US fl oz
13.2 imp oz
A beer bottle that is half the capacity of a 750 mL champagne/wine bottle. Reused champagne punts were used in the 19th century to ship lager beer to Australia, establishing it as the beer "quart". When metrication was introduced in the 1970s, the Reputed Pint (131⁄3 imp oz [379 mL]) was replaced with the 375 mL stubbie.
Schooner (UK)

Beer sales in Britain and the Commonwealth are based on multiples of 1⁄3, 1⁄2, and full imperial pints.[note 2] Imperial-measure glasses were 568 mL, and metric-measure glasses round up to 570 mL. Beer bottles in the UK were rounded down to 550 mL after standard metrication was introduced in 1995, later changed to 500 mL by January 1, 2000. After December 31, 1999, the imperial pint was no longer considered a legal measure except for draught beer, cider, and milk in reusable pint and quart bottles.

1.14 imp pt
1⁄6 US gallon, rounded up from 21.3 US fl oz. Also called a "bomber" or a "double deuce" (from the two #2s, or "deuces", in its volume). Mostly replaced by the 40 US fl oz bottle by the late 1980s, but still used by some breweries for beer and malt liquor. Metric measure containers are rounded down to 650 mL. The US 23-ounce beer glass holds a sixth of beer, plus the head.

Standard Australian bottle size, equal to half of an Imperial gallon. Later rounded down to 2.25 L (79.18 imp fl oz) after metrication, or reduced to 2 L (70.39 imp fl oz) in states with strict drinking laws.
An obsolete Dutch measurement, originally used for a small cask of wine or brandy. It was brought to the New World by the former Dutch colony of Nieuw Amsterdam (renamed to New York City by the English in 1664). It was adopted by Colonial New York and New Jersey as a standard measure and was retained by America after independence. It was also used in Europe, where it varied in capacity from 9 to 11 US gallons.

1⁄6 Gill (Imp.)
5⁄6 imp fl oz
23.7 mL
25 mL
Legal serving of spirits (gin, rum, vodka and whisky) defined in the Weights and Measures Act of 1963 (1963-1984). Rounded up to 25 mL in 1985. Scotland and Northern Ireland (and British premises grandfathered in before the act was enforced) were allowed to keep their larger measures, as long as the glassware was consistent and marked and advertised as such.
Shot (UK)
25 mL
Legal serving of spirits (gin, rum, vodka and whisky) in the UK since 1985.[15]
Shot sizes vary significantly from country to country. In the United Kingdom, serving size in licensed premises is regulated under the Weights and Measures Act (1985). A single serving size of spirits (gin, whisky, rum, and vodka) are sold in 25 ml or 35 ml quantities or multiples thereof.[21] Beer is typically served in pints (568 ml), but is also served in half-pints or third-pints. In Israel, a single serving size of spirits is about twice as much, 50 or 60 mL.
The shape of a glass can have a significant effect on how much one pours. A Cornell University study of students and bartenders' pouring showed both groups pour more into short, wide glasses than into tall, slender glasses.[22] Aiming to pour one shot of alcohol (1.5 ounces or 44.3 ml), students on average poured 45.5 ml & 59.6 ml (30% more) respectively into the tall and short glasses. The bartenders scored similarly, on average pouring 20.5% more into the short glasses. More experienced bartenders were more accurate, pouring 10.3% less alcohol than less experienced bartenders. Practice reduced the tendency of both groups to over pour for tall, slender glasses but not for short, wide glasses. These misperceptions are attributed to two perceptual biases:
Estimating that tall, slender glasses have more volume than shorter, wider glasses; and
Over-focusing on the height of the liquid and disregarding the width.

The "Reputed Pint" (2⁄3 Imperial pint or 1⁄12 Imperial gallon) was devised to split a standard gallon into twelve small bottles. Originally it was based on the British Wine gallon, which was later adopted by the United States as their standard fluid gallon. This made a Wine Gallon "Reputed Pint" equivalent to 2⁄3 US liquid pint (10.66 US fluid oz.), 11.09 imp. oz, or 315 mL. Although the Imperial system was introduced in 1824, bottles of ale or beer were still sold in Reputed Pints (13.3 imperial oz) but were now based on the Imperial gallon (based on the British Ale Gallon). It was later replaced by the Imperial Pint (20 imp oz / 568 ml) in the 20th century.

-
651 ml
A sixth (1⁄6, or 0.166) of a US Gallon, rounded up from its actual volume of 21.33 US fl oz. Formerly used for cheap liquor like gin and vodka. It was supposed to be replaced by the 500 mL "half-liter", which was dropped in 1989, but is sometimes used for craft beer and malt liquor.
A fifth (1⁄5, or 0.2) of a US gallon. Called a "Commercial Quart" because it was equivalent to 0.8 US fluid quarts. Replaced by the 750 mL "metric quart".
Reputed Quart (UK)
25.6 US fl oz
26.66 imp oz.
757 mL
The "Reputed Quart" (2⁄3 Imperial quart or 1⁄6 Imperial gallon) was devised to split a standard gallon into six large bottles and was usually used for wine and liquor. Originally it was based on the British Wine gallon, which was later adopted by the United States as their standard fluid gallon. When the Imperial system was introduced in 1824, measures of wine or liquor were still sold in either Reputed Quarts (26.6 imp oz.) or Imperial Quarts (40 imp oz.). It was later replaced by the Imperial Quart (40 imp oz / 1136 ml) in the 20th century.
Quart (Imp.)
38.5 US fl oz

A half (1⁄2, or 0.5) of a US gallon. Replaced by the 1.75 L "metric half-gallon" in 1976.
The British Reputed Pint and Reputed Quart were used in Great Britain and throughout the Empire from the late 17th century until the early 20th century. Originally there were different standard gallons depending on the type of alcohol. That meant that the Reputed measures varied depending on which standard gallon was used. A Reputed Pint of beer was equal to 285 mL (1/2 an Ale Pint, or equivalent to 10 imperial oz. or 9.63 US oz.) and a Reputed Quart of wine was equal to 730 mL (3/4 of a Wine Quart, or equivalent to 25.69 Imp. oz. or 24.68 US fluid oz.). When the Imperial system was adopted in 1824, the fluid gallon was standardized on the old Ale Gallon (which had 160 fluid ounces). However, Reputed pints and quarts were still used by breweries and merchants, but measurements were now based on the Imperial system. There was still confusion about whether Reputed or Imperial measures was being used by the merchant, so eventually Imperial pints and quarts were made standard in the early 20th century.
The United States adopted the British Wine Gallon (which had 128 fluid ounces) as standard. The laws concerning the production and sale of alcohol stated that it had to be sold in portions of a gallon for tax purposes. A standard case of bottled beer, wine or liquor had to be equal to two gallons and bottles came in half-dozens and dozens rather than fourths (quarts) and eighths (pints). There would be 24 small bottles (Twelfths of a US gallon) or 12 large bottles (Sixths of a US gallon) per case. The bottles were later increased in size (Tenths and Fifths of a US gallon) to be equivalent to British Reputed Pints and Quarts, allowing them to be interchangeable for export. The American liquor industry later referred to these measures as "Commercial Pints" (Tenths) and "Commercial Quarts" (Fifths).
Wine measurements
The following table contains various measurements that are commonly applied to wine.[26]
Popular size for wines introduced by Austrian Grüner Veltliner wine producers in the late 1990s.[32] Also used by German, Chilean and American producers since the late 2000s.
Magnum
50.7
1.5 L
2
Marie Jeanne
76
2.25 L
3
Bordeaux region. Usually used for a Claret wine bottle.
Tregnum
76
2.25 L
3
Port wine bottle. Also called "Tappit hen",[33] from a Scottish breed of chicken from the Shetland Isles with a tuft of feathers on the top of its head. The red sealing wax over the cork stopper resembles a red tuft of feathers.
The 750 mL Standard wine bottle was chosen because it was the standard French wine bottle once moulded glass bottles were available in the 19th century. Previously there was a roughly 730 mL limit to glass-blown bottles because that was the limit of a glassblower's lungs. The volume was rounded up to 750 mL and then was used as the base size for French wine containers, with all subdivisions and multiples figured from it. The rest of the world followed suit with equivalent customary measurement versions of their own (like the British Reputed Quart).
Following metrication in 1980, American still wines can also be sold in large multi-liter containers, but only in full liters. They are typically sold in glass demijohns or foil bag-in-box containers holding 4, 5, 7, 8, or 10 Liters.
Used for domestically produced sparkling white wine in the place of the French metric 375 mL champagne punt. Rounded-down from 12.68 US fl oz (375 mL). Still wines (Red, White, and Rosé) came in US pint (16 US fl. oz., or 473 mL) and Tenth (12.8 US fl.oz., or 378 mL) bottles. Replaced in 1980 with the metric 375 mL Demi Bottle for both still and sparkling wines.
