The estate is located in the municipality of Barsac in the area Sauterne
(Graves, Bordeaux). It should not be confused with the Château Suau of the same name in the municipality of Capian (Premières Côtes de Bordeaux). The origin goes back to the end of the 17th century, at that time the Tarneau family owned it. Through marriage, the Suau family came into possession. After many changes of ownership, the vineyards (not the château) have belonged to Roger Biarnès since 1961. The wine is produced at its second estate, Château Navarro in Cérons. In the Bordeaux Classification
in 1855 it was classified as "Deuxième Cru Classé" (Sauternes). The vineyards cover eight hectares and are planted with the varieties Sémillon (80%), Sauvignon Blanc (10%) and Muscadelle (10%). The storable noble sweet wine is aged in used barriques. The red wine varieties occupy a much larger area with 50 hectares.
