Beaujolais nouveau is a red wine made from Gamay grapes produced in the Beaujolais region of France. The Beaujolais region had always made a vin de l’année to celebrate the end of the harvest, but until WWII it was only for local consumption. In fact, once the Beaujolais AOC was established in 1937, AOC rules meant that Beaujolais wine could only be officially sold after the 15th December in the year of harvest. These rules were relaxed on 13 November 1951, and the Union Interprofessionnelle des Vins du Beaujolais (UIVB) formally set the 15 November as the release date for what would henceforth be known as Beaujolais nouveau. Most recently, in 1985, the date was changed to the third Thursday in November.
