This branch of the Dagueneau family headed by father Serge is based in Saint Andelain and owns 19 hectares of old vineyards across several of the prime sites of the appellation as well as 3 hectares in the nearby appellation of Cotes de la Charite. Today the estate is run by Serge's daughter Valerie, cousin of the late Didier Dagueneau, and Serge still helps in the vineyard.

While the calcareous soil in the vineyards give the wines ample structure and the ability to age gracefully, the vineyards of Pouilly Fumé typically have more clay and depth than the poorer more chalky soils of neighbouring Sancerre. This is particularly so in the prime area of Saint Andelain where most of the family's vineyard holdings are located.

The work in the vineyard has since 2017 been certified HEV3 (High Environmental Value) and since 2018 some vineyards are trialing to bio-dynamic conversion. The soils are partly planted with cover crops, and partly ploughed, and the family have reduced their dependence on herbicides, in recent years. Today there are 18 ha planted to Sauvignon blanc in the Pouilly Fume appellation and roughly 1 ha planted to Chasselas for the Pouilly sur Loire appellation. These particular vines are ancient, aged more than one hundred years, and they are propagated by the age-old method of marcottage. Most of these vines are planted on Kimmeridgian marl, one of the classic terroirs of both appellations.
