A distilled beverage, spirit, liquor, or hard liquor is an alcoholic beverage produced by distillation of a mixture produced from alcoholic fermentation. This process purifies it and removes diluting components like water, for the purpose of increasing its proportion of alcohol content (commonly expressed as alcohol by volume, ABV). As distilled beverages contain more alcohol they are considered "harder" – in North America, the term hard liquor is used to distinguish distilled beverages from undistilled ones, which are implicitly weaker.
As examples, this does not include beverages such as beer, wine, and cider, as they are fermented but not distilled. These all have relatively low alcohol content, typically less than 15%. Brandy is a spirit produced by the distillation of wine, and has an ABV over 35%. Other examples of distilled beverages include vodka, gin, rum, whisky, eau de vie (fruit brandy or schnapps), tequila, baijiu, soju, aguardiente, pálinka, cachaça, singani, borovička and slivovitz.
The term spirit refers to a distilled beverage that contains no added sugar and has at least 20% alcohol by volume (ABV).
Distilled beverages bottled with added sugar and added flavorings, such as Grand Marnier, Frangelico, and American schnapps, are known instead as liqueurs. In common usage, the distinction between spirits and liqueurs is widely unknown or ignored; as a consequence, in general, all alcoholic beverages other than beer and wine are referred to as spirits.
Beer and wine, which are not distilled beverages, are limited to a maximum alcohol content of about 20% ABV, as most yeasts cannot reproduce 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" was the Latin verb liquere, meaning "to be fluid". According to the Oxford English Dictionary, an early use of the word in the English language, meaning simply "a liquid", can be dated to 1225. The first use the OED mentions of its meaning "a liquid for drinking" occurred in the 14th century. Its use as a term for "an intoxicating alcoholic drink" appeared in the 16th century.
The term "spirit" in reference to alcohol stems from Middle Eastern alchemy. These alchemists were more concerned with medical elixirs than with transmuting lead into gold. The vapor given off and collected during an alchemical process (as with distillation of alcohol) was called a spirit of the original material.
History of distillation
The first clear evidence of distillation comes from Greek alchemists working in Alexandria in the 1st century AD, although the Chinese may have independently developed the process around the same time. Distilled water was described in the 2nd century AD by Alexander of Aphrodisias. The Alexandrians were using a distillation alembic or still device in the 3rd century AD.
The medieval Arabs learned the distillation process from the Alexandrians and used it extensively, but there is no evidence that they distilled alcohol.
Freeze distillation involves freezing the alcoholic beverage and then removing the ice. The freezing technique had limitations in geography and implementation and limiting how widely this method was put to use.
The earliest evidence of true distillation of alcohol comes from the School of Salerno in southern Italy during the 12th century. Again, the Chinese may not have been far behind, with archaeological evidence indicating the practice of distillation 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.
Paracelsus experimented with distillation. His test was to burn a spoonful without leaving any residue. Other ways of testing were to burn a cloth soaked in it without actually harming the cloth. In both cases, to achieve this effect, the alcohol had to be at least 95 percent, close to the maximum concentration attainable through distillation (see purification of ethanol).
Claims upon the origin of specific beverages are controversial, often invoking national pride, but they are plausible after the 12th century AD, when Irish whiskey and German brandy became available. These spirits would have had a much lower alcohol content (about 40% ABV) than the alchemists' pure distillations, and they were likely first thought of as medicinal elixirs. Consumption of distilled beverages rose dramatically in Europe in and after the mid-14th century, when distilled liquors were commonly used as remedies for the Black Death. Around 1400, methods to distill spirits from wheat, barley, and rye beers, a cheaper option than grapes, were discovered. Thus began the "national" drinks of Europe: jenever (Belgium and the Netherlands), gin (England), Schnaps (Germany), grappa (Italy), horilka (Ukraine), akvavit/snaps (Scandinavia), vodka (Poland and Russia), ouzo (Greece), rakia (the Balkans), and poitín (Ireland). The actual names emerged only in the 16th century, but the drinks were well known prior to then.
In some jurisdictions in the United States, it is legal for unlicensed individuals to make their own beer and wine. However, it is illegal to distill beverage alcohol without a license anywhere in the US. In some jurisdictions, it is also illegal to sell a still without a license.
It is legal to distill beverage alcohol as a hobby for personal use in some countries, including Italy, New Zealand, Netherlands, and (to a limited degree) the United Kingdom.
Microdistilling (also known as craft distilling) as a trend began to develop in the United States following the emergence and immense popularity of microbrewing and craft beer in the last decades of the 20th century. It is different from megadistilling in the quantity and quality of output.
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 is called its flash point. The flash point of pure alcohol is 16.6 °C (61.9 °F), less than average room temperature.)
The flash points of alcohol concentrations from 10% ABV to 96% ABV are:
- 10% — 49 °C (120 °F) — ethanol-based water solution
- 12.5% — about 52 °C (126 °F) — wine
- 20% — 36 °C (97 °F) — fortified wine
- 30% — 29 °C (84 °F)
- 40% — 26 °C (79 °F) — typical vodka, whisky or brandy
- 50% — 24 °C (75 °F) — strong whisky
- 60% — 22 °C (72 °F) — normal tsikoudia (called mesoraki or middle raki)
- 70% — 21 °C (70 °F) — absinthe, Slivovitz
- 80% — 20 °C (68 °F)
- 90% or more — 17 °C (63 °F) — neutral grain spirit
Distilled beverages can be served:
- Neat — at room temperature without any additional ingredient(s)
- Up — shaken or stirred with ice, strained, and served in a stemmed glass.
- On the rocks — over ice cubes
- Blended or frozen — blended with ice
- With a simple mixer, such as club soda, tonic water, juice, or cola
- As an ingredient of a cocktail
- As an ingredient of a shooter
- With water
- With water poured over sugar (as with absinthe)
Alcohol consumption by country
The World Health Organization 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 a given year in a country.
