Wine growers in Barsac have the choice of marketing their wine under the Barsac AOC or Sauternes AOC. This means that all Barsac wines could also be Sauternes wines but Sauternes wines are forbidden from wearing Barsac on their label.
The total area is 830ha over gravel, red sand and a clayey-limestone base with approximately the same predominance of Sauvignon Blanc, Sémillon and Muscadelle planted.
