The Sauternes area is located on the left bank of the Garonne River, 40 km upstream from the city of Bordeaux. This area consists of 5 villages: Sauternes, Preignac, Bommes, Fargues and Barsac. The first four are on the right bank of Ciron (tributary of Garonne) and Barsac is on the left bank of the Ciron. The Barsac appellation benefits from a specific microclimate because of the confluence of cold water from Ciron and warmer water from the Garonne; thus, morning mists develop in autumn that are quickly expelled by the sun. This climatic variation promotes the development of noble rot (Botrytis Cinerea). The terroir consists of several layers of gravel, chalk and gravel. These layers, deposited over time by the rivers, allow the wine to build its finesse, power and lushness.
After selection in the vineyard, the shriveled grapes undergo a final check in the winemaking room. Fermentation takes place in 6 concrete vats. The best quality, from the oldest vines continues as Château Dudon. This wine matures for 18 months in 225-liter French oak barriques. The slightly less concentrated second wine is called Gallien de Chateau Dudon and matures in concrete vats for about 8 months. The style of the 2 wines is different. The Gallien is fine-bodied, packed with elegant fruit impressions and is finely sweet. The Château wine has more complexity, more filling and the barrel aging used elegantly adds a level.
