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. [ 1 ] [ 2 ] [ 3 ] 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 volume of such a mixture is slightly less than the sum of the volumes of the components. Thus, by the above definition, the term "40% alcohol by volume" refers to a mixture of 40 volume units of ethanol with enough water to make a final volume of 100 units, rather than a mixture of 40 units of ethanol with 60 units of water.
To make 50% alcohol by volume fraction, one would take 50 parts alcohol and 50 parts water, measured separately, and then mix them together. The resulting volume will not be 100 parts but between 96 and 97 parts, since the smaller water molecules can take up some of the space between the larger alcohol molecules (see volume change ).
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.
United States standard drinks of beer, malt liquor, wine, and spirits compared. Each contains about 14 grams or 17.7 ml of ethanol. A standard drink or (in the UK) unit of alcohol is a measure of alcohol consumption representing a fixed amount of pure alcohol.
Drinks containing alcohol are typically divided into three classes—beers, wines, and spirits—with alcohol content typically between 3% and 50%. Drinks with less than 0.5% are sometimes considered non-alcoholic. Many societies have a distinct drinking culture, where alcoholic drinks are integrated into parties.
According to the Canadian Food and Drug Regulation, gin is produced through redistillation of alcohol from juniper berries or a mixture of more than one such redistilled food products. [27] The Canadian Food and Drug Regulation recognises gin with three different definitions (Genever, Gin, London or Dry gin) that loosely approximate the US ...
[29] [5] Mezcal can reach an alcohol content of 55%. [29] Like tequila, mezcal is distilled twice. The first distillation is known as ordinario, and comes out at around 75 proof (37.5% alcohol by volume). The liquid must then be distilled a second time to raise the alcohol percentage.
