Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation, usually inside an apparatus known as a still. Dry distillation is the heating of solid materials to produce gaseous products ; this may involve chemical changes such as destructive distillation or cracking. Distillation may result in essentially complete separation, or it may be a partial separation that increases the concentration of selected components; in either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but is a physical separation process, not a chemical reaction. An installation used for distillation, especially of distilled beverages, is a distillery. Distillation includes the following applications:
Gin is a distilled alcoholic drink that derives its flavour from juniper berries and other botanical ingredients.
Vodka is a clear distilled alcoholic beverage. Different varieties originated in Poland, Russia, and Sweden. Vodka is composed mainly of water and ethanol but sometimes with traces of impurities and flavourings. Traditionally, it is made by distilling liquid from fermented cereal grains, and potatoes since introduced in Europe in the 1700's. Some modern brands use corn, sugar cane, fruits, honey, and maple sap as the base.
Whisky or whiskey is a type of liquor made from fermented grain mash. Various grains are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden casks, which are typically made of charred white oak. Uncharred white oak casks previously used for the aging of port, rum or sherry are also sometimes used.
Moonshine is high-proof liquor, generally whiskey, traditionally made, or at least distributed, illegally. Its clandestine distribution is known as bootlegging. The name was derived from a tradition of creating the alcohol during the nighttime, thereby avoiding detection. In the first decades of the 21st century, commercial distilleries have adopted the term for its outlaw cachet and begun producing their own legally sanctioned, novelty "moonshine," including many flavored varieties, that in some sense continue its tradition, generally having a similar method and/or location of production.
Irish whiskey is whiskey made on the island of Ireland. The word 'whiskey' comes from the Irish uisce beatha, meaning water of life. Irish whiskey was once the most popular spirit in the world, though a long period of decline from the late 19th century onwards greatly damaged the industry, so much so that although Ireland boasted at least 28 distilleries in the 1890s, by 1966 this number had fallen to just two, and by 1972 the remaining distilleries, Bushmills Distillery and Old Midleton Distillery, were owned by just one company, Irish Distillers.
Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. Generally the component parts have boiling points that differ by less than 25 °C (45 °F) from each other under a pressure of one atmosphere. If the difference in boiling points is greater than 25 °C, a simple distillation is typically used. It is used to refine crude oil.
A pot still is a type of distillation apparatus or still used to distill liquors such as whisky or brandy. In modern (post-1850s) practice, they are not used to produce rectified spirit, because they do not separate congeners from ethanol as effectively as other distillation methods. Pot stills operate on a batch distillation basis. Traditionally constructed from copper, pot stills are made in a range of shapes and sizes depending on the quantity and style of spirit desired.
A column still, also called a continuous still, patent still or Coffey still is a variety of still consisting of two columns. Column stills can produce rectified spirit.
Arak or araq is a distilled Levantine spirit of the anise drinks family. It is translucent and unsweetened.
Fusel alcohols or fuselol, also sometimes called fusel oils in Europe, are mixtures of several higher alcohols produced as a by-product of alcoholic fermentation. The word Fusel[ˈfuːzl̩] is German for "bad liquor".
Liquor is an alcoholic drink produced by the distillation of grains, fruits, vegetables, or sugar that have already gone through alcoholic fermentation. Other terms for liquor include: spirit, distilled beverage, spirituous liquor or hard liquor. The distillation process concentrates the liquid to increase its 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 common in the UK. 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.
Rectified spirit, also known as neutral spirits, rectified alcohol or ethyl alcohol of agricultural origin, is highly concentrated ethanol that has been purified by means of repeated distillation in a process called rectification. In some countries, denatured alcohol or denatured rectified spirit may commonly be available as "rectified spirit", because in some countries the retail of rectified alcohol in its non-denatured form is prohibited.
Fragrance extraction refers to the separation process of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression, sieving, or enfleurage. The results of the extracts are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product.
Bathtub gin refers to any style of homemade spirit made in amateur conditions. The term first appeared in 1920, in the prohibition-era United States, in reference to the poor-quality alcohol that was being made.

Reflux is a technique involving the condensation of vapors and the return of this condensate to the system from which it originated. It is used in industrial and laboratory distillations. It is also used in chemistry to supply energy to reactions over a long period of time.
Moonshine is a generic term for distilled alcoholic beverages made throughout the globe from indigenous ingredients reflecting the customs, tastes, and raw materials for fermentation available in each region. The term commonly applies to small-scale production, which is often illegal or tightly regulated in many countries, in the same order that is for example making food.
Downslope Distilling is a craft beverage distillery in Centennial, Colorado, United States.
The Botanist is a dry gin made by the Bruichladdich Distillery on Islay, Scotland. It is one of the two gins made on the island and is known for its hand-foraged botanicals. The botanicals are collected from all over Islay by professional foragers between March and October. The name of the gin was inspired by two local botanists who helped develop the recipe for the gin alongside former Master Distiller, Jim McEwan.
