The winery is located in the municipality of Barsac in the area Sauterne
(Graves, Bordeaux). It must not be confused with the homonymous Château Suau in the commune of Capian (Premières Côtes de Bordeaux). The origin goes back to the end of the 17th century, when the owner was the Tarneau family. By marriage it came into the possession of the eponymous family Suau. After many ownership changes belong to the vineyards (not the Château) since 1961 Roger Biarnès. The wine is produced on 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 matured in used barriques. The red wines occupy a much larger area with 50 hectares.
