(written from a Production point of view)
Bordeaux was a type of French wine from the Bordeaux region of France. In the script for "We'll Always Have Paris", in Jean-Luc Picard's re-creation of the Café des Artistes aboard the USS Enterprise-D in 2364, the waiter Edouard poured a glass of bordeaux for Picard. The waiter described the wine as coming from a very passionate year. At the request of Picard, the waiter, as well, poured a glass of Bordeaux for Gabrielle.
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.
