The alcohol by volume shown on a bottle of absinthe. 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.
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 ...
Chart showing alcohol unit count for drink size and ABV. In the UK, it is sometimes misleadingly stated that there is one unit per half-pint of beer, or small glass of wine, or single measure of spirits. However, such statements do not take into account the various strengths and volumes supplied in practice.
The strength of beer is measured by its alcohol content by volume expressed as a percentage, that is to say, the number of millilitres of absolute alcohol (ethanol) in 100 mL of beer. The most accurate method of determining the strength of a beer would be to take a quantity of beer and distill off a spirit that contains all of the alcohol that ...

On 1 January 1980, Britain adopted the ABV system of measurement prescribed by the European Union, of which it was then a member. The OIML recommendation for ABV used by the EU states the alcohol by volume in a mixture containing alcohol as a percentage of the total volume of the mixture at a temperature of 293.15 K [20.00 °C; 68.00 °F].
The Standard Reference Method or SRM [1] is one of several systems modern brewers use to specify beer color. Determination of the SRM value involves measuring the attenuation of light of a particular wavelength (430 nm) in passing through 1 cm of the beer, expressing the attenuation as an absorption and scaling the absorption by a constant (12.7 for SRM; 25 for EBC).
In practice, most bars will use the same size measure as for the four spirits. [ 5 ] The 1963 act formalized the legal measures by which spirits and other alcoholic beverages should be dispensed, namely 1 ⁄ 4 , 1 ⁄ 5 or 1 ⁄ 6 gill (36, 28 or 24 ml), but this was replaced in 1985 when 25 ml or 35 ml were permitted.
