Hi Holly... Sorry for the delay in responding. The truth is, the forum was not really up and running yet. I was busy working on the main site. But the forums are about ready to be used.
I do not have enough information on the wine you are asking about. However, the name implies it is a simple, generic Bordeaux wine that was produced by the Nathaniel Johnston Negociant company. They are still in business today.
You can post an image if you like. Or if you can let me know if the label offers any additional information such as the vintage, or the appellation, if there is one, which I doubt, that would help.
