Château Les Graves de Viaud is a family-owned estate located in Côtes de Bourg, taken over in 2010 by Philippe Betschart and his mother Françoise. After careers unrelated to wine, they decided to reconnect with their Bordeaux roots and converted the estate to biodynamic farming. In 2014, they created the brand "La Colombine," which includes their natural wines made from their own grapes and white grapes provided by a partner. All their wines are certified organic, and the reds are Demeter-certified biodynamic.

Spanning 15 hectares, including 5.5 hectares of vineyards on south-facing clay-gravel soils, the estate is committed to environmentally friendly agriculture. Beyond organic and biodynamic certifications, the château practices conservation agriculture, without animal manure, and produces its wines naturally, without oenological additives or animal products. This is done with a focus on innovation and respect for nature, offering authentic and unique wines.
