Bordeaux was a type of French wine from the Bordeaux region of France. Chateau Picard, in La Barre, was a producer of this type. (PIC: "The Star Gazer")
According to background material created for Star Trek Generations, the 2305 vintage of Chateau Picard Bordeaux was awarded a "Certificate of Excellence in Winemaking" from the Terran Winemakers Association. This variety of Bordeaux had received the certificate Appellation Bordeaux contrôlée earlier. Confirmation of Chateau Picard producing Bordeaux in canon happened in the episode "The Star Gazer" when workers stacked boxes bearing the label "Grand Vin de Bordeaux".
The article containing this information was included in the Picard family album during the filming of Generations. However, the information is non-canon as the article was never seen on-screen.
