Château Dauphiné-Rondillon was created in 1798 by Mr Alfred Debat. From the beginning, he decided to devote himself exclusively to the production of great sweet white wines. His descendant, Basile Debat, won a gold medal for a Loupiac 1900 at the Concours Général Agricole in 1901. Encouraged by this recognition of quality, Jean Darriet decided in 1920 to bottle his wine. The Château's label, created that year, has remained unchanged ever since. Overlooking the Garonne River, the Château is situated on the most beautiful terroirs of Loupiac and rises to 103 metres. From the property, it is easy to see some of the Grands Crus of Sauternes: Rayne-Vigneau, Yquem, Rieussec, Lafaurie-Peyraguey. This exceptional terroir is made up of a large gravelly ridge on the surface, followed by a clay-gravel soil, before reaching the limestone bedrock. The combination of this terroir, a south/south-west exposure, and a privileged geographical location offer exceptional conditions for the production of great sweet white wines. The work in the vineyard is carried out in a traditional manner and with respect for the environment: all the tasks in the vineyard are done manually (pruning, thinning out, harvesting). Organic amendments are controlled, treatments are carried out with natural contact products such as sulphur flower. The vegetative cycle and natural control are favoured with grassing in every other row.
