Who said Bordeaux lacked a sense of storytelling?

Last week, I came across this bottle in a restaurant. The label also recounts the following tale: 'Legend has it that in 1809, the Empress, accompanying Napoleon to the wars in Spain, felt an urgent call of nature whilst passing by the edge of this vineyard. Ever since, this plot, registered in the cadastre under the name "Congaillard", has produced wines enjoying an honourable reputation.' No need for a château name, just a story to tell.
