1. Law on brand names

The first law on trademarks was passed on June 23rd of 1857. It is now possible to deposit a brand by means of a name or a logo. In 1864 both Hennessy and Hine were among the first to register their name and logo.

2. Legislation on transport and origine

Like any other commercial goods cognac was taxed already in the 17th century. Amongst the most common methods was taxing goods when they had to be transported. To this purpose the Aydes system was introduced. The people of the Aydes (or Aides) collected tax and provided wine-growres and producers an acquittal or ‘Acquit’, the proof that taxes had been paid.
On March 27 of 1872 the Acquit was officially registered by decree as a document called ‘titre de transport’. At first there was no specification of the geographical origine of the product in this document. That changed in 1903.  On March 31 of that year the Acquit Blanc was introduced for those products of which the origin could be guaranteed by the government. For the products of which the origin could not be guaranteed, the old Acquit remained in place. This was printed on red paper and was therefore called ‘Acquit Rouge’.

In the storage buildings of the merchants eau-de-vie was devided in these two categories: cognac with an acquit rouge and cognac with an acquit blanc. One unexpectant result was that cognacs with an acuit rouge were much more sought after than those with an acquit blanc for a period of time. Never mind the origin was not being guaranteed! Cognacs with an acquit rouge were much older than those with an acquit blanc.
When transported abroad, both acquits were taken in by the border authorities, so this guarantee never reached the foreign customers.

On August 4th, 1929 another law was passed in which the Acquit Jaune d’Or was introduced. It was printed on yellow-gold paper and it provided much more clarity because the origin of the product was stated much more specific. The Acquit Jaune d’Or had three parts, one of which was designed for the foreign customers. The other two acquit’s (blanc and rouge) were abandoned.

3. Legislation on authenticity

The Law of August 1st, 1905 made fraud and deceit regarding the authenticity of the product punishable by imprisonment. So from now on not only the origin of the product could be legally guaranteed, but also the authenticity. Authenticity relates to the genuineness of the raw material that is used in producing the eau-de-vie.

Next in 1907 a law is passed ordering that no substance whatsoever is to be added that could alter the composition or the taste. But an exception was made for sweetening and colouring the product, within certain limits.

The region for the production of cognac was specified by the Law of May 1, 1909. It was accompanied by a map, drawn by M. Guillon, a viticultural inspector. He used the 1887 map from mr. Mouchet as his starting point.

Mouchet 1887  Guillon map 1909

Almost 30 years later, on May 15 1936 the ‘appellation d’origine controlée de cognac’ is adopted by decree for eau-de-vie de Cognac originating from the region that was specified in the Law of May 1, 1909. This decree also specifies the denomination Fins Champagne and the regions Grande Champagne, Petite Champagne, Borderies, Fins Bois, Bons Bois, Bois Ordinaires and Bois à terroirs. But the exact delimitation of these regions was only specified two years later by the Law of November 30th of 1938, where the 1936 Decree was complemented with an enumeration of all the departments, districts and communities of the cognac region. Some communities are not fully part of the cognac region and are mentioned by name.
(By the way: all regions were already stated in a law of January 13th, 1938. All communities were also called by name in this law.)

The Law of May 6th, 1919 stipulated that every individual person and every company was entitled to initiate legal actions when deceit was suspected regarding the appellation of cognac.
Moreover this Law emphasized the requirement for all spirits to come from one region and one Cru to be recognized as coming from that particular cru, meaning that all cognac must be from wines grown in that area and distilled in the cognac region. The whole process being under the strict control of the State.

A new law saw the light on July 22nd, 1927 to warrant the quality of the product even further. In this law the allowed grape varieties were limited to those that were customary in use for a long time and generally acknowledged by the local wine-growers. This of course meant the end of hybrids who often had a much greater, but gave an inferior end-product.

The Law of February 20th, 1928 legalized the term ‘Fine’. The use of the word ‘Fine’ is restricted to eau-de-vie made of wine or cider and is accompanied by a geographical vinicultural or cider-production appellation. Its purpose is to explicitely state that the named eau-de-vie or cider originates exclusively from that region.

4. Law in relation to foreign countries

During the Madrid conference of April 4th, 1891 the principle was acknowledged that ‘appellations’ of wine products could not have a generic meaning. In other words: a copy of a product made in another country or region was not allowed to take the name of a product for which an appellation was in place. So a brandy from the cognac region, made of ugni blanc grapes and distilled using the methode Charentaise was allowed to be called cognac, but a brandy from Spain made of ugni blanc and produced using the same method, not.

This principle now was very poorly lived up to by the participating Member States. They felt not interested, while this principle also applied to products from their own countries. Initially this agreement was only signed by a small number of countries. But in the decennia that followed, France always endeavoured to persuade other countries to sign the agreement. Sadly even today there are still some countries that have not signed yet.

5. Law on production methods and specification of the regions

A very important Law was delivered on May 15th, 1936 in which the appellation d’origine controlé is recorded for the first time and in which some methods for the production are specified. The cru’s are mentioned again and also the grape varieties to be used.

  • regarding the origine of the wine: it is mandatory that it is harvested and distilled in the region of the appellation.
  • seven cru’s are stated: Grande Champagne, Petite Champagne, Borderies, Fins Bois, Bons Bois, Bois Ordinaires and Bois à Terroirs. ‘Fine Champagne’ is also recognized as an ‘appellation controlé’.
  • allowed grape varieties are : Ugni blanc, Folle blanche, Colombard, Blanc-ramé (syn. Meslier-Saint-François) , Jurançon blanc, Montils, Sémillon.
  • also allowed: Sélect, for 10% max.
  • no sugar shall be added to the wine.
  • usage of the continuous screw-press (or Archimedes press) is not allowed.
  • double distillation (methode Charentaise) is mandatory.
  • the eau-de-vie is not allowed to exceed 72 per cent alcohol.
  • the still (chaudière) is to be heated by a naked flame only.
  • the still used for the second distillation (bonne chauffe) must not hold more than 30 hectolitres and may not be loaded with more than 25.
  • the still used for the first distillation is allowed to hold a maximum of 140 hectolitres and to be loaded up to 120 hectolitres.
  • when sold to the customer eau-de-vie having an appellation cognac must have a minimum of 40 per cent of alcohol.
  • all wine must be distilled before the 31st of March of the year following the year of distillation. Wine that is distilled after this date is not entitled to be called appellation cognac.

On January 13th 1938 the ‘sous-appellations’ are defined by Law: Grande Champagne, Petite Champagne, Fine Champagne, Borderies, Fins Bois, Bons Bois. Note that Bois Ordinaires and Bois à Terroirs are not allowed to a sous-appellation. Also noteworthy is the denomination ‘Fine Champagne’ because this does not designate one specific origine, but a blend of Grande and Petite Champagne.

The Décret of  June 16th, 2011 essentially lists all legal provisions from the past, with some legal provisons and extensions that were added over time:

  • appellation controlé de Cognac and its geographical indications: departements, districts, municipalities and if necessary townships.
  • additional geographical indications: Grande Fine Champagne, Grande Champagne, Petite Fine Champagne, Petite Champagne, Fine Champagne, Borderies, Fins Bois, Bons Bois, Bois Ordinaires and Bois à Terroirs: all municipalities with the exception of the Bois Ordinaires and Bois à Terroirs, who are not allowed to a sub-appellation.
  • the allowed grape varieties: colombard B, folle blanche B, montils B, sémillon B, ugni blanc B; also folignan B with a maximum of 10% of the vineyard. Jurançon blanc B, meslier saint-françois B and sélect B are only allowed for vineyards planted before September 18th, 2005. They are permitted until the harvest in the year 2020.

6. Laws on the age of cognacs

As of October 15th, 1924 an obligation, imposed by the indirect taxation authorities, was in force to register all eaux-de-vie of one, two and three years of age. This was caused by the Australian demand for an age-certificate issued by the French government. Up to that time age-certificates were issued by the maior of the city.
In the period 1925-1940 several amendmends to this regulation were made, but a complete and sound control system was very hard to realize. During World War II this control system watered down completely.

The judgement of February 20th, 1946 assigns the responsability for controling the ages of eau-de-vie to the Bureau National Interprofessionel de Cognac (BNIC). This judgement also stipulates that the age of a blend (‘coupe’) is determined by its youngest component.
And from this day on the obligation, imposed by the BNIC, is in force to keep detailed records of all eaux-de-vie with its age and origin.

On October 27th, 1953 the BNIC provides that the designations VO, VSOP and Réserve were only to be used for cognacs with compte 4 and designations Extra, Napoléon and Vieille Réserve for cognacs with compte 6. In 1955 this provision was once more ratified. Compte 6 incidentally, came officially into force in 1979.
Also in 1955 the date on which the ages of cognac increase with one year changed from September 1, the start of the harvest season, to April 1, the end of the distillation period.

In 1962 single vintage cognacs were banned. A few exceptions were made: early landed cognacs (these were ageing in England) and three cognac houses who held a perfect registration and could prove the provenance regarding year and district of their eau-de-vie. These three were Croizet-Eymard, Delamain and Hine.
In 1987 this ban was lifted again.

On September 20th 1967 the comptes-system is expanded by the BNIC. Now compte 00 is also precisely defined. There are now seven comptes: 00, 0,1, 2, 3, 4, 5.
As of April 1st, 1979 compte 6 is added for cognacs of 6 years and older.

August 23rd, 1983: The BNIC decides (Décision du commissaire du Gouvernement près le BNIC) to recognize the following qualitative age-categories, based on the youngest eau-de-vie present in a blend:

  • VS (Very Special) minimum of two years on cask (also called three stars)
  • VSOP (Very Superior Old Pale or Very Special Old Pale), minimum of four years on cask
  • XO (Extra Old), minimum of 6 years this has changed in 2016 to ten years)

From 1994 till 2000 the comptes 7 till 10 are introduced. These are laid down in the ‘Arrêté de 27 Juin 2003’.


History of Cognac legislation — 8 Comments

  1. Hi!
    Just seen a bottle of cognac listed at an auction taking place in September 2022. 1811 and with a label with ‘Grande Fine Champa’ (torn label!) ‘Napoleon
    Appellation 1811 Cont’ written on. The ‘Appellation Cont’ seems suspicious to me, considering it was 1936 before Appellation d’Origin Controllee it came into effect, especially considering an estimate starting at £20,000. I have come across a few counterfeit wines before, and would feel aggrieved if someone else was to be ripped off.
    Of course I maybe wrong, but I might save some poor unsuspecting soul a small fortune!!

    • I think you are referring to the Chateau Paulet bottle. You might be right, especially since a lot of fraud was committed with that year (1811). But the appellation controlée only indicates that the cognac was bottled after the appellation legislation was a fact. It is still possible that the 1811 cognac was stored in dame jeannes until then. So it is not yet proof.

  2. “In 1962 single vintage cognacs were banned Except for Croizet-Eymard, Delamain and Hine.”

    Does this mean all cognac vintages from 1962-1987 have to be from these three houses? Since this isn’t the case, how were the vintages from that period ‘checked and locked away by the BNIC?’.

    Thank you!

    • No this does not mean all cognac vintages from 1962-1987 have to be from these houses. During 1962 and 1987 (some authors claim it was until 1985 and I even read 1989 in a book by Calabrese) only Hine, Croizet and Delamain were allowed to SELL vintage cognacs. That is not the same as stating there are no vintages of these years. When this was agreed upon (it seems it was not a decree, anyway I have not been able to find a law or decree, not even in Landrau’s book of “Le cognac devant la Loi”) you can imagine producers did start to take measures so that when the ban was lifted they had cognacs of these years that were well documented and probably also checked.

      • Really appreciate the extra tid bit of information cognacton, thank you.

        Mind if I follow up with some extra questions?

        I am curious about the ‘lot’ designation. Lot 19 No. 70 would mean 1970 right? is that just a way around to state a vintage? why not just say 1970 on a single cask vintage? Any ideas on where the TWA 49 year cognac house is from?

        Also as an expert in this field, do you have any pet peeves on things that cognac drinkers do? (brandy heaters, rancio chasers etc?)

        Lastly, do you have anywhere to help donate to the cost of running this web? I’m not rich but I don’t want to take things for free either.

        Much appreciated.

        • To start with your last question – I really appreciate the thought – I have not set up such a thing as a donation possibility.
          About the numbers they use, yes, you are right. Most of the times they use it like that, but not always.
          Some use alternative methods: Rue 69 for instance, meaning 1969 (Vallein-Tercinier).
          I tried to find which producer made the cognac for The Whisky Agency, but I have not been able to find it yet (though Vallein-Tercinier could be a candidate). There are other societies that have brought cognacs on the market, like SMWS (Scotch Malt Whisky Society, LMDW (La Maison du Whisky, who make ‘Through the Grapevine’ cognacs). I don’t know who produced them either. In other cases I do know this, for instance some hotels and restaurants and some UK shops or wineries.
          Pet peeves: I only know of some who collect figurines, mostly Asian people. And of course miniatures. But they don’t bother me.


  3. This was exactly what I was looking for! Thank you!
    Love the chatty undertownes.
    Maybe you could suggest some other websites or books to read, when one is looking to become somewhat of a Cognac expert?
    Thanks again 🙂

    • Thank you for the compliments.

      I have done a page on books to read, but it is in Dutch. You can have a look here. You can run the Dutch text through Google translate. The first one (Koops) is only in Dutch, the others are available in several languages.
      And here you can find a more extensive list with ISBN numbers.
