Alcohol by volume in the context of "Drink"

Sake, saké (Japanese: 酒, Hepburn: sake; English: IPA: /ˈsɑːki, ˈsækeɪ/ SAH-kee, SAK-ay), or saki, also referred to as Japanese rice wine, is an alcoholic beverage of Japanese origin made by fermenting rice that has been polished to remove the bran. Despite the name Japanese rice wine, sake, and indeed any East Asian rice wine (such as huangjiu and cheongju), is produced by a brewing process more akin to that of beer, where starch is converted into sugars that ferment into alcohol, whereas in wine, alcohol is produced by fermenting sugar that is naturally present in fruit, typically grapes. This process is called Multiple Parallel Fermentation.

Although similar, the brewing process for sake differs from the process for beer, in which the conversion from starch to sugar and then from sugar to alcohol occurs in two distinct steps. Like other rice wines, these conversions occur simultaneously when brewing sake. The typical alcohol content also differs between sake, wine, and beer; while most beer contains 3–9% ABV and wine generally contains 9–16% ABV, undiluted sake contains 18–20% ABV (although this is typically lowered somewhat by diluting with water prior to bottling).

An alcoholic beverage is any drink that contains alcohol, a central nervous system depressant. They are typically divided into three classes: beers, wines, and spirits; with alcohol content typically between 3% and 50%. The exact amount on which a beverage is considered alcoholic differs by country, with some considering drinks containing less than 0.5% to be non-alcoholic. These beverages are primarily consumed for the psychoactive effects that they produce.

Many societies have a distinct drinking culture, in which alcoholic drinks are integrated into parties. Most countries have laws regulating the production, sale, and consumption of alcoholic beverages. Some regulations require the labeling of the percentage alcohol content (as ABV or proof) and the use of a warning label. Some countries ban the consumption of alcoholic drinks, but they are legal in most parts of the world. The temperance movement advocates against the consumption of alcoholic beverages. The global alcoholic drink industry exceeded $1.5 trillion in 2017. Alcohol is one of the most widely used recreational drugs in the world, and about 33% of all humans currently drink alcohol. In 2015, among Americans, 86% of adults had consumed alcohol at some point, with 70% drinking it in the last year and 56% in the last month. Several other animals are affected by alcohol similarly to humans and, once they consume it, will consume it again if given the opportunity; however, humans are the only species known to produce alcoholic drinks intentionally.

Beer is an alcoholic beverage produced by the brewing and fermentation of starches from cereal grain—most commonly malted barley, although wheat, maize, rice, and oats are also used. The grain is mashed to convert starch in the grain to sugars, which dissolve in water to form wort. Fermentation of the wort by yeast produces ethanol and carbonation in the beer. Beer is one of the oldest and most widely consumed alcoholic drinks in the world, and one of the most popular of all drinks. Most modern beer is brewed with hops, which add bitterness and other flavours and act as a natural preservative and stabilising agent. Other flavouring agents, such as gruit, herbs, or fruits, may be included or used instead of hops. In commercial brewing, natural carbonation is often replaced with forced carbonation.

Beer is distributed in bottles and cans, and is commonly available on draught in pubs and bars. The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. The strength of modern beer is usually around 4% to 6% alcohol by volume (ABV).

Liquor (/ˈlɪkər/ LIK-ər, sometimes hard liquor), spirits, distilled spirits, or spiritous liquor are alcoholic drinks produced by the distillation of grains, fruits, vegetables, or sugar that have already gone through alcoholic fermentation. While the word liquor ordinarily refers to distilled alcoholic spirits rather than drinks produced by fermentation alone, it can sometimes be used more broadly to refer to any alcoholic beverage (or even non-alcoholic ones produced by distillation or some other practices, such as the brewed liquor of a tea).

The distillation process concentrates the alcohol, so the resulting condensate has an increased 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 the production of brandy and whiskey, or are infused with flavorings to form flavored liquors, such as absinthe.

Cider (/ˈsaɪdər/ SY-dər) is an alcoholic beverage made from the fermented juice of apples. Cider is widely available in the United Kingdom (particularly in the West Country) and Ireland. The United Kingdom has the world's highest per capita consumption, as well as the largest cider-producing companies. Ciders from the South West of England are generally higher in alcoholic content. Cider is also popular in many Commonwealth countries, such as India, South Africa, Canada, Australia, New Zealand, and New England. As well as the UK and its former colonies, cider is popular in Portugal (mainly in Minho and Madeira), France (particularly Normandy and Brittany), northern Italy (specifically Friuli), and northern Spain (specifically Asturias and Basque Country). Germany also has its own types of cider with Rhineland-Palatinate and Hesse producing a particularly tart version known as Apfelwein. In the U.S. and Canada, varieties of alcoholic cider are often called "hard cider" to distinguish it from non-alcoholic apple cider or "sweet cider", also made from apples. In Canada, cider cannot contain less than 2.5% or over 13% absolute alcohol by volume.

The juice of most varieties of apple (including crab apples) can be used to make cider, but cider apples are best. The addition of sugar or extra fruit before a second fermentation increases the ethanol content of the resulting beverage. Cider alcohol content varies from 1.2% to 8.5% ABV or more in traditional English ciders, and 2.5% to 12% in continental ciders. In UK law, it must contain at least 35% apple juice (fresh or from concentrate), although CAMRA (the Campaign for Real Ale) says that "real cider" must be at least 90% fresh apple juice. In the US, there is a 50% minimum. In France, cider must be made solely from apples.

Dimensionless quantities, or quantities of dimension one, are quantities implicitly defined in a manner that prevents their aggregation into units of measurement. Typically expressed as ratios that align with another system, these quantities do not necessitate explicitly defined units. For instance, alcohol by volume (ABV) represents a volumetric ratio; its value remains independent of the specific units of volume used, such as in milliliters per milliliter (mL/mL).

The number one is recognized as a dimensionless base quantity. Radians serve as dimensionless units for angular measurements, derived from the universal ratio of 2π times the radius of a circle being equal to its circumference.

Rubbing alcohol, known as surgical spirit in the British Pharmacopoeia, refers to a group of denatured alcohol solutions commonly used as topical disinfectant. In addition to its medical applications, rubbing alcohol is employed in various industrial and household contexts. These solutions are primarily composed of either isopropyl alcohol (isopropanol) or ethanol, with isopropyl alcohol being the more widely available formulation.

The United States Pharmacopeia (USP) defines "isopropyl rubbing alcohol USP" as a solution containing approximately 70% alcohol by volume of pure isopropanol, while "rubbing alcohol USP" refers to a solution containing approximately 70% by volume of denatured ethanol. In Ireland and the United Kingdom, the comparable product is "surgical spirit B.P.", defined by the British Pharmacopoeia as containing 95% methylated spirit, 2.5% castor oil, 2% diethyl phthalate, and 0.5% methyl salicylate. Known alternatively as "wintergreen oil", methyl salicylate is also a common additive in North American rubbing alcohol products.
