From 65438 to 0855, Charles Louis Napolé on Bonaparte was in power. King III wanted to take the opportunity of the Paris World Expo to promote Bordeaux wines to the whole world. He wanted all the wines from all over the country to participate in the exhibition. Therefore, he asked the Bordeaux Wine Chamber to prepare an exhibition to introduce Bordeaux wines and classify Bordeaux wineries. This is tantamount to stirring up a hornet's nest, because those wineries are self-righteous, but there can only be one winner. So the Bordeaux Chamber of Commerce shifted the responsibility to Syndicat of Courtiers, the official organization of a wine wholesaler, and asked them to divide all wineries into five grades, and every wine producer in Gironde District was included in one grade. Two weeks later, the Syndicat of Courtiers came up with their classification, including 58 wineries, 1 super, 4 first-class, 12 second-class, 14 third-class,10/4,/kloc. The first-class winery is d'Yquem, and the first-class wineries are Lafite-Rothschild, Latour, Margaux and Upper Briant.

1973, the grade winery was modified. Whether the winery is renamed, split or merged, it has maintained its original grade. The only exception is that Mouton's Mouton-Rothschild winery was upgraded from the original second-class winery to 1 class winery. At this time, the number of grade wineries has increased to 6 1, among which, premium wineries 1, five first-class wineries, two-class wineries 14, three-class wineries 14, four-class wineries 18 and five-class wineries 18.
