A reader has this beautiful vintage cognac bottle at home: Rouyer, Guillet, Genuine Napoléon, 1811. The bottle is located in Fairfield County, Connecticut, USA. This bottle was purchased for $10.00 at an estate sale in Westport, CT. around 1977-79. The woman running the sale unfortunately began to “clean” the bottle with a damp rag before being told to stop. Thus, most of the dust and a couple flakes of wax from the cork area were removed.

    Hello Roman and Sebastian,

    I sent a few additional photos to Sebastian.

    The owner is my mother; I took the photos for her but only per the requirements set in the photo submission form. Alas, I do not live close by, so the owner is going to ask a friend to take more photos of the capsule for you.

    I did, however, take a few other photos which may be of use in the meantime. One is a slightly higher angled photo of the capsule which shows a bit more of the rear bottleneck chipped wax. Another is a photo of the blown glass bottom edge, and finally a photo taken through the bottle which shows the rear of the shoulder button.

    There appears to be some sort of clay/glue which had been extruded to act as a fixture between the glass and the wax. Perhaps someone here can use this to determine when and by whom this was bottled.

    Speaking for the owner, we appreciate the knowledge and help of cognac-expert.com in trying to determine what we have here with this old find.

    (Remark by Admin: As the condition of the capsule is the crucial point for old bottles, I posted respective images only. Thank you for your understanding)

    thank you for the extra pictures, will be glad to see the others when you get them. the wax button does not get glued to the bottle it adheres on its own when poured hot just like the wax on the capsule and if you see something in between them it is probably something that was applied afterword to keep the button on as it fall off. also i’d like to know if the content is clear or if there are partials in the liquid.

    The content is clear, no particles. About the wax button- it does not appear to have ever come loose. It has some fine cracks in it, but the wax which curves around the glass would have broken. I have looked for photos of other blown bottles with applied shoulder buttons (not molded) and cannot find any. If any reader can help out with this feature, I’d appreciate it.

    please clarify what you are saying with this ” There appears to be some sort of clay/glue which had been extruded to act as a fixture between the glass and the wax. “

    Hi Roman,
    The clay-looking glob appears to only exist to make a more shallow vessel (and even surface) of the shoulder button, in which to pour the wax.
