On this website I like to share all the information on Cognac that I have gathered over the years.
I want to present all this information in an orderly manner: about the production process, the history of cognac, the cognac producers and so on. This is an enormous task and will not be finished in a few days or even weeks. So it is a project in progress. In the next weeks and months I will add new content on the site.

In the above menu under ‘Brands and producers>brands‘ you can find a lot of information on the major brands. Under ‘Brands and producers>on the map‘ you will find a map with every cognac producer around. The rest of the menu speaks for itself.
Don’t forget to do the quiz (test your knowledge).

  1. Good morning I have just been given a bottle of Rouyer and guillet ltd bottle of 3 star cognac. it has a cork top and three bricks or steps on the label. it looks like about 70cl and is 70 proof. would you be able to give me some information on this please.

    • Hi,
      With three bricks or steps? It doesn’t ring a bell. Could you send me a picture?
      I’ll send you an e-mail.


  2. Hey Ton
    I love your site, thanks for providing such a useful resource.

    I’m trying to date a bottle of Courvoisier which I’m sure I bought back from a skiing trip quite some time ago.

    Using your Courvoisier Bottle Catalog PART 1 page I’ve identified it under code 2b5, but I don’t know how to use your coding system as a dating tool. Can you tell me what date range is covered by 2b5 please?



    • Thank you Dennis.
      I try to put the oldest series first and the newest last. For Courvoisier it is difficult. It seems several bottle types coexisted in the same period. But the ‘2b5’-bottles were from the 1980-1990s. Maybe there are addional marks on the back of the bottle that could help to date it. On this page is some helpful information: https://cognac-ton.nl/en/home-page/other-topics/dating-a-bottle/

      Good luck,

  3. Hi

    Please let me have an E-Mail-Adresse as I would like to send you a photo of a label I am sure you will not have

    Kind regards


  4. Hey Ton, first of all let me thank you for all of your work – It has helped me a lot in identifying my dad’s collection. Although there are for sure many bottles that you do not have in the catalogue. As I am yet not very willing to reveal my collection to public in person – I would be happy to have your opinion and of course fill in the missing bits in your stunning website
    Please drop me an email,

  5. Hello,

    I think I have bottle label which you do not have on your website. Please email me if you are interested in buying it.

    Many thanks,

    • Hi,
      Are you sure? Did you try the search site box?

      If so, I would like to know the name of the label, but I am not interested in buying.


  6. I have a bottle of cognac which doesn’t seem to be listed on your very informative site. It’s very similare but different text on thé label which reads “O.F. Martinel. Vers Old Pale, Trade Mark on Capsules & Cases. However, if you would like a photo for completeness I would be happy to e-mail some to you, maby you have informations about it

    Kind Regards

  7. Hello Ton,

    I recently acquired a bottle of Remy Martin cognac which doesn’t seem to be listed on your otherwise very informative site. It’s very similar in appearance to the 2nd bottle from the left in the “7. Age d’Or and Age Inconnu” section, but differs by having a shoulder label which reads “Grande Reserve”. The label states it is No. 54199; Grande Fine Champagne de Remy Martin. It probably isn’t particularly old. However, if you would like a photo for completeness I would be happy to e-mail some to you.

    Kind regards,

  8. Hello Peter,

    I would be happy to receive a picture of a new bottle. I can try to give you information, but it depends a bit on the picture. It will be a UK bottle of approximately 68cl.
    I will send you an e-mail address to send the picture to.


  9. Hi
    I have a bottle of Martell with 24 fl ozs and 70 proof but i can’t see a bottle with the same label could i send a picture of the label and would you have any info on it.


    • Hello Philippe,

      Likewise for sure. It is always an honour to meet such a prominent person in the cognac world!

      Kind regards,

  10. Dear Tom,

    I got to your blog by finding a google map made by you with plenty of cognac producers. That is quite a big job you did, and I am amazed. We are a small family company working on writing The Alphabetical Encyclopedia of Cognac. We also dedciate our time to educational projects about cognac, and we created a World Cognac Institute. Its main goal is to educate students at the Hotel Academies of European Union.

    This is a Virtual Tour of Cognac Embassy in Kosice:

    I just wanted to get in touch with you as we like the same things.
    Thank you, and I wish you all the best

    Kindest regards


    • Hello Renata,

      Thank you for taking an interest in my website. I am afraid most of it is in Dutch, but I am thinking of translating more pages into English.
      I took a look at your VR website and I could take a look into a few rooms. There is a lot of cognac in there and I spotted a fair amount of Scandinavian marques. I could not find any other information, but I presume it is a project in progress?
      I wish you a lot of success with writing the Encyclopedia of Cognac.

      Kind regards,
