Cognac is the best known type of Brandy in the world, a benchmark by which most other Brandies are judged. The Cognac region is located on the west-central Atlantic coast of France, just north of Bordeaux, in the departments of Charente and Charente-Maritime. The region is further subdivided into six growing zones: Grande Champagne, Petite Champagne, Bois Ordinaries, Borderies, Fins Bois, and Bons Bois. The first two of these regions produce the best Cognac and will frequently be so designated on bottle labels. Cognacs labelled Fine Champagne are a blend of Petite and Grande Champagne. The primary grapes used in making Cognac are Ugni Blanc, Folle Blanche, and Colombard. The wines made from these grapes are thin, tart, and low in alcohol; poor characteristics for table wines, but oddly enough, perfect for making Brandy. Cognac is double distilled in pot stills and then aged in casks made from Limousin or Troncais oak. All Cognacs start out in new oak to mellow the fiery spirit and give them color. Batches that are chosen for long-term aging are, after a few years, transferred to used, or "seasoned," casks that impart less of the oak flavor notes while the Brandy matures.
Virtually all Cognacs are a blend of Brandies from different vintages, and frequently, different growing zones. Even those from single vineyards or distilleries will be a mix of Brandies from different casks. As in Champagne, the production of local vineyards is sold to Cognac houses, each of which stores and ages Cognacs from different suppliers and then employs master blenders to draw from these disparate Brandies to create continuity in the house blends. Because there are no age statements on Cognacs, the industry has adopted some generally accepted terms to differentiate Cognacs. It is important to note that these terms have no legal status, and each Cognac shipper uses them according to his own criteria.
V.S./V.S.P./Three Star:
(V.S., very superior; V.S.P., very superior pale) A minimum of two years aging in a cask, although the industry average is four to five years.
V.S.O.P.:
(very superior old pale) A minimum of four years cask aging for the youngest Cognac in the blend, with the industry average being between 10 and 15 years.
X.O./Luxury:
(X.O., extra old) A minimum of six years aging for the youngest cognac in the blend, with the average age running 20 years or older. All Cognac houses maintain inventories of old vintage Cognacs to use in blending these top of the line brands. The oldest Cognacs are removed from their casks in time and stored in glass demijohns (large jugs) to prevent further loss from evaporation and to limit excessively woody and astringent flavors. Luxury Cognacs are the very finest Cognacs of each individual Cognac house.
Armagnac is the oldest type of Brandy in France, with documented references to distillation dating back to the early 15th century. The Armagnac region is located in the heart of the ancient province of Gascony in the southwest corner of France. As in Cognac, there are regional growing zones: Bas-Armagnac, Haut Armagnac, and Tenareze. The primary grapes used in making Armagnac are likewise the Ugni Blanc, Folle Blanche, and Colombard. But distillation takes place in the unique alambic Armagnacais, a type of column still that is even more "inefficient" than a typical Cognac pot still.
The resulting brandy has a rustic, assertive character and aroma that requires additional cask aging to mellow it out. The best Armagnacs are aged in casks made from the local Monlezun oak. In recent years Limousin and Troncais oak casks have been added to the mix of casks as suitable Monlezun oak becomes harder to find.
Most Armagnacs are blends, but unlike Cognac, single vintages and single vineyard bottlings can be found. The categories of Armagnac are generally the same as those of Cognac (V.S., V.S.O.P., X.O., etc.). Blended Armagnacs frequently have a greater percentage of older vintages in their mix than comparable Cognacs, making them a better value for the discerning buyer.
French Brandy is the catch-all designation for Brandy produced from grapes grown in other regions. These Brandies are usually distilled in column stills and aged in oak casks for varying periods of time. They are frequently blended with wine, grape juice, oak flavorings, and other Brandies, including Cognac, in order to smooth out the rough edges. Cognac-like quality designations such as V.S.O.P. and Napoleon are frequently used, but have no legal standing.
