Wine bottle?

[capsoda]

Languedoc-Roussillon in lower France but I would be more in favor of Loire Valley in upper France. It is a seafood and rich food area. I do know that at one time almost all the winerys there marked their bottles with an L but I don't know if it was the mark on your bottle.

Thanks Warren, it is more than just a possibility.
