After the Belle Epoque of 1900, the last edition of the Féret before the First World War was published in 1908, a year of unrest and crisis in the winemaking world. Château Fonbadet,owned by Bernard Coudert, was ranked among the top Crus Bourgeois Supérieurs of Pauillac. In the aftermath of the First World War, the Bordeaux wine trade would never be the same again. The short-lived recovery of the 20s came to a bitter end with the 1929 crash and with prohibition in the United States.
Château Fonbadet was classified as a Médoc Cru Bourgeois Supérieur in 1932, confirming its position as one of the very best unclassified Pauillac growths, according to the 1855 Classification.
The continuity of the Cru de Fonbadet over the centuries is particularly noteworthy in a context where many other leading Pauillac growths disappeared, taken over by neighbouring Grands Crus.
