Cognac (/ˈkɒnjæk/ KON-yak or /ˈknjæk/ KOHN-yak; French pronunciation: ​[kɔ.ɲak]) is a variety of brandy named after the town of Cognac, France. It is produced in the surrounding wine-growing region in the departments of Charente and Charente-Maritime.

Cognac production falls under French Appellation d'origine contrôlée designation, with production methods and naming required to meet certain legal requirements. Among the specified grapes Ugni blanc, known locally as Saint-Emilion, is most widely used.[2] 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 barrel age, and most cognacs spend considerably longer "on the wood" than the minimum legal requirement.

Production process

Cognac is a type of brandy and, after the distillation and during the aging process, is also called eau de vie.[3] It is produced by doubly distilling white wines produced in any of the designated growing regions.


The white wine used in making cognac is very dry, acidic and thin. Though it has been characterized as "virtually undrinkable",[4] 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 cru, the wine must be at least 90% Ugni blanc (known in Italy as Trebbiano), Folle blanche and Colombard, while up to 10% of the grapes used can be Folignan, Jurançon blanc, Meslier St-François (also called Blanc Ramé), Sélect, Montils or Sémillon.[5][6] 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

A Charentais style alembic cognac pot still

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.[7] At this point, the resulting wine is about 7% to 8% alcohol.[7]

Distillation takes place in traditionally shaped Charentais copper alembic stills, 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.[4]


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%.[4] 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.[4] This phenomenon is called locally "La part des anges", or "The angels' share". Because the alcohol dissipates faster than the water, the alcohol concentration drops to about 40% over time.[4] The cognac is then transferred to large glass carboys called bonbonnes, then stored for future blending.[4] Since oak barrels stop contributing to flavor after four or five decades, longer aging periods may not be beneficial.[4]


The age of the cognac is calculated as that of the youngest component 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.[8] 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 single malt Scotch whisky).[9] 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.


VS (Very Special) cognac is aged for at least two years in cask
XO (Extra Old) cognac is aged at least six years
"Champagne cognac" is produced from grapes grown in the Grande Champagne and Petite Champagne zones of the Cognac region of France

According to the Bureau National Interprofessionnel du Cognac (BNIC), the official quality grades of cognac are the following:

  • V.S. (Very Special) or ✯✯✯ (three stars) designates a blend in which the youngest brandy has been stored for at least two years in cask.[10]
  • V.S.O.P. (Very Superior Old Pale) or Reserve designates a blend in which the youngest brandy is stored for at least four years in a cask.[10] [11]
  • XO (Extra Old) or Napoléon currently designates a blend in which the youngest brandy is stored for at least six years.[10] The minimum storage age of the youngest brandy used in an XO blend will be increased to ten years in April 2018; this rule was originally scheduled for implementation in 2016 but was postponed due to inadequate stocks.[12] The Napoleon designation, previously unofficial, will then be used to specifically denote those blends with a minimum age of six years that do not meet the revised XO definition.[13]
  • 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 product beyond the official age scale.

The names of the grades are in English because the historical cognac trade, particularly in the 18th century, significantly involved the British.[14]

Producing regions

Map of the Cognac region

Cognac is also classified by crus, tightly defined geographic denominations where the grapes are grown. Their distinctive soils and microclimates produce eaux de vie with characteristics particular to their specific location.

  • Grande Champagne (13,766 hectares (34,020 acres)) The soils in Grande Champagne and Petite Champagne are characterized as shallow clay-limestone, over limestone and chalk.[15]
  • Petite Champagne (16,171 hectares (39,960 acres)) Petite Champagne eaux de vie have similar characteristics to those from Grande Champagne. 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".[15]
  • Borderies (4,160 hectares (10,300 acres)) The smallest cru. This denomination's soil contains clay and flint stones resulting from the decomposition of limestone.[15]
  • Fins Bois (34,265 hectares (84,670 acres)) Heavier and faster aging eaux de vie ideal for establishing the base of some blended cognacs. The soils here are predominantly red clay-limestone and very stony, or otherwise heavy clay soils.[15]
  • Bons Bois and Bois Ordinaires (together 19,979 hectares (49,370 acres)). Further out from the four central growth areas are these two growing regions. With a poorer soil and very much influenced by the maritime climate, this area is 20,000 hectares.
  • Bois à terroirs The soils of Les Bois (Bons Bois, Bois Ordinaires, and Bois à terroirs) are sandy, spanning coastal areas and some valleys.[15]

The cognac-producing regions called Champagne 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.

Companies and brands

There are close to 200 cognac producers.[1] According to one 2008 estimate[16] a large percentage of cognac—more than 90% for the US market—comes from only four producers: Courvoisier (owned by Beam Suntory), Hennessy (LVMH), Martell (Pernod Ricard), and Rémy Martin (Rémy Cointreau).[4][16] Other brands meeting the AOC criteria for cognac include: Bache-Gabrielsen/Dupuy, Braastad, Camus, La Fontaine de La Pouyade, Château Fontpinot,[16] Delamain, Pierre Ferrand,[4] Frapin, Gautier, Hine,[16] Marcel Ragnaud,[4] Moyet, Otard, Meukow, and Cognac Croizet.
