The winery is located in the municipality of Bommes in the Sauternes region (Graves, Bordeaux). A Madame Marie Peyronne de Rabaud brought the Château Rabaud as a dowry when she married Arnaud de Cazeau in 1660. After more than 150 years, it was acquired by Gabriel Deyme in 1819, who sold it to Henri Drouilhet de Sigalas in 1864. In the 1855 Bordeaux Classification, the estate was classified as a Premier Cru Classé (Sauternes) under the name Château Rabaud. Henri subsequently also bought the former Château Pexoto and integrated the areas of this estate, which was classified as Deuxième Cru Classé, into Château Rabaud, which nevertheless retained its status as Premier Cru Classé. However, his son Pierre Drouilhet de Sigalas parted with part of the estate in 1903 and sold it to Adrien Promis. The latter named his new property Château Rabaud-Promis.
The Sigalas family's remaining share was given the name Château Sigalas-Rabaud. In 1929, Henri's son Gérard inherited the estate and later bequeathed it to his daughter, who married the Marquis René de Lambert de Granges. The Marquis hired Pierre Ginestet, who was already responsible for Château Rabaud-Promis. Until 1949, the two wines were marketed separately, but produced by the same team. The collaboration only ended with a change of ownership at Château Rabaud-Promis in 1953, which probably led to the final separation. The Lambert de Granges family founded an operating company in 1972 in order to avoid having to divide up the estate through possible succession; they are the majority owners. The vineyards cover 14 hectares and are planted with Sémillon (98%) and Sauvignon Blanc (2%). The extremely long-lasting, noble sweet wine is matured for 18 to 20 months in barriques, one third of which are new. The second wine is called "Le Cadet de Sigalas".
