The Halley family, previously majority shareholders in Carrefour, have sold Chateau de La Dauphine in Fronsac to the Labrune family, founders of Cegedim, a global buisness providing information technology services for the health industry, with revenues of about €500m.

Chateau de la Dauphine has 40 hectares of vines producing about 200,000 bottles of wine per year. It is the second larget estate in the Fronsac appellation after Chateau de la Rivière. Following their acquisition of the estate in December 2000 the Halley family initiated a major restructuring programme, replanting parts of the vineyard and constructing a state-of-the-art production facility that includes a gravity-fed vat room. The vineyard commenced conversion to organic viticulture in 2012 and should be fully certified for the 2015 vintage. In addition to winning praise from various critics for the quality of their wines in recent vintages the estate has also developed a successful wine tourism activity.
