Cognac (pron.: // KON-yak ; French pronunciation: [kɔ.ɲak]), named after the town of Cognac in France, is a variety of brandy. It is produced in the wine-growing region surrounding the town from which it takes its name, in the French Departements of Charente and Charente-Maritime.
For a distilled brandy to bear the name Cognac, an Appellation d'origine contrôlée, its production methods must meet certain legal requirements. In particular, it must be made from specified grapes (see below), of which Ugni blanc, known locally as Saint-Emilion, is the one most widely used. The brandy must be twice distilled in copper pot stills and aged at least two years in French oak barrels from Limousin or Tronçais. Cognac matures in the same way as whiskies and wine when aged in barrels, and most cognacs are aged considerably longer than the minimum legal requirement.
Producing region and legal definitions 
|This section does not cite any references or sources. (December 2010)|
The region authorised to produce cognac is divided into six zones, including five crus broadly covering the department of Charente-Maritime, a large part of the department of Charente and a few areas in Deux-Sèvres and the Dordogne. The six zones are: Grande Champagne, Petite Champagne, Borderies, Fins Bois, Bon Bois and finally Bois Ordinaire. A blend of Grande and Petite Champagne Cognacs, with at least half coming from Grande Champagne, is known as Fine Champagne.
Cognac-producing regions should not be confused with the northeastern region of Champagne, a wine region that produces sparkling wine by that name, although they do share a common etymology – both being derivations of a French term for chalky soil.
Production process 
The white wine used in making cognac is very dry, acidic and thin. Though it has been characterized as "virtually undrinkable", it is excellent for distillation and aging. It may be made only from a strict list of grape varieties. In order for it to be considered a true crus, the wine must be at least 90% Ugni blanc (known in Italy as Trebbiano), Folle blanche and Colombard, although 10% of the grapes used can be Folignan, Jurançon blanc, Meslier St-François (also called Blanc Ramé), Sélect, Montils or Sémillon. Cognacs which are not to carry the name of a cru are freer in the allowed grape varieties, needing at least 90% Colombard, Folle blanche, Jurançon blanc, Meslier Saint-François, Montils, Sémillon, or Ugni blanc, and up to 10% Folignan or Sélect.
Fermentation and distillation 
After the grapes are pressed, the juice is left to ferment for two or three weeks, with the region's native, wild yeasts converting the sugar into alcohol; neither sugar nor sulfur may be added. At this point, the resulting wine is about 7 to 8% alcohol.
Distillation takes place in traditionally shaped Charentais copper stills, also known as an alembic, the design and dimensions of which are also legally controlled. Two distillations must be carried out; the resulting eau-de-vie is a colourless spirit of about 70% alcohol.
Once distillation is complete, it must be aged in Limousin oak casks for at least two years before it can be sold to the public. It is typically put into casks at an alcohol by volume strength of about 70%. As the cognac interacts with the oak barrel and the air, it evaporates at the rate of about three percent each year, slowly losing both alcohol and water. Because the alcohol dissipates faster than the water, the alcohol concentration drops to about 40% over time. The cognac is then transferred to large glass carboys called bonbonnes, then stored for future blending. Since oak barrels stop contributing to flavor after four or five decades, longer aging periods may not be beneficial.
The age of the cognac is calculated as that of the youngest eau-de-vie used in the blend. The blend is usually of different ages and (in the case of the larger and more commercial producers) from different local areas. This blending, or marriage, of different eaux-de-vie is important to obtain a complexity of flavours absent from an eau-de-vie from a single distillery or vineyard. Each cognac house has a master taster (maître de chai), who is responsible for blending the spirits, so that cognac produced by a company will have a consistent house style and quality. In this respect it is similar to the process of blending whisky or non-vintage Champagne to achieve a consistent brand flavor. A very small number of producers, such as Guillon Painturaud and Moyet, do not blend their final product from different ages of eaux-de-vie and therefore produce a 'purer' flavour (a practice roughly equivalent to the production of a single-cask Scotch whisky). Hundreds of vineyards in the Cognac AOC region sell their own cognac. These are likewise blended from the eaux-de-vie of different years, but they are single-vineyard cognacs, varying slightly from year to year and according to the taste of the producer, hence lacking some of the predictability of the better-known commercial products. Depending on their success in marketing, small producers may sell a larger or smaller proportion of their product to individual buyers, wine dealers, bars and restaurants, the remainder being acquired by larger cognac houses for blending. The success of artisanal cognacs has encouraged some larger industrial-scale producers to produce single-vineyard cognacs.
According to the interprofessional French institution BNIC (Bureau National Interprofessionnel du Cognac), the official quality grades of cognac are the following:
- V.S. ("very special"), Very Special, or ✯✯✯ (three stars) designates a blend in which the youngest brandy has been stored for at least two years in cask.
- V.S.O.P. ("very superior old pale") designates a blend in which the youngest brandy is stored for at least four years in a cask, but the average wood age is much greater.
- XO ("extra old") designates a blend in which the youngest brandy is stored for at least six years but on average for upwards of 20 years. In 2016, the minimum storage age of the youngest brandy used in an XO blend will be set to ten years.
The names of the grades are in English because the historical cognac trade, particularly in the 18th century, significantly involved the British, as explained at the BNIC website.
In addition the following grades can be mentioned:
- Napoleon is a grade equal to XO in terms of minimum age, but it is generally marketed in-between VSOP and XO in the product range offered by the producers.
- Extra designates a minimum of 6 years of age, this grade is usually older than a Napoleon or an XO.
- Vieux is another grade between the official grades of VSOP and XO.
- Vieille Réserve is, like the Hors d´Âge, a grade beyond XO.
- Hors d'âge ("beyond age") is a designation which BNIC states is equal to XO, but in practice the term is used by producers to market a high-quality[editorializing] product beyond the official age scale.
The crus where the grapes were grown can also be used to define the cognac, and give a guide to some of the flavor characteristics of the cognac:
- Grande Champagne (13,766 hectares (34,020 acres)) Grande Champagne eaux de vie are long in the mouth and powerful, dominated by floral notes.[original research?] "Champagne" derives from the Roman "Campania" meaning Plain, but is often explained[by whom?] with similarity in soil with the Champagne area at Reims.
- Petite Champagne (16,171 hectares (39,960 acres)) Petite Champagne eaux de vie have similar characteristics to those from Grande Champagne but are in general shorter on the palate. Cognacs made from a mixture of Grande and Petite Champagne eaux de vie (with at least 50% Grande Champagne) may be marketed as "Fine Champagne".
- Borderies (4,160 hectares (10,300 acres)) The smallest cru, eaux de vie from the Borderies are the most distinctive,[editorializing] with nutty aromas and flavor, as well as a distinct violet or iris characteristic.
- Fins Bois (34,265 hectares (84,670 acres)) Heavier and faster aging eaux de vie ideal for establishing the base of some blended cognacs. Fins Bois is rounded and fruity, with an oiliness.[original research?]
- Bons Bois
- Bois Ordinaires (19,979 hectares (49,370 acres) together with Bons Bois). Further out from the four central growth areas are the Bons Bois and the Bois Ordinaires grown regions. With a poorer soil and very much influenced by the maritime climate, this area of 20,000 hectares produces eaux de vie that are less demonstrative[editorializing] and age more quickly.
The growth areas are tightly defined; there exist pockets with soils atypical of the area producing eaux de vie that may have characteristics particular to their location. Hennessy usually uses the unofficial brandy grades for its cognac offerings, but has also produced three single distillery cognacs, each with distinctive flavors arising from the different soils and, to a lesser extent, climate. Other cognac houses, such as Moyet, exclusively use the crus to describe their different cognacs.
Companies and brands 
While there are close to 200 cognac producers, a large percentage of cognac—90% according to one 2008 estimate—is produced by only four companies: Courvoisier, Hennessy, Martell, and Rémy Martin. Other brands include: Bache-Gabrielsen/Dupuy, Braastad, Camus, La Fontaine de La Pouyade, Chateau Fontpinot, Delamain, Pierre Ferrand, Frapin, Hine, Marcel Ragnaud, Moyet, Otard and Cognac Croizet.
In popular culture 
Cognac has become ingrained in hip hop culture.
