Duffour Père et Fils is a family-owned producer from Côtes de Gascogne in south-western France. The Duffour family established the estate in 1955. From the 1970s onwards, Michel Duffour played an important role in developing the winery, before his son Nicolas continued the family tradition as the third generation. The estate is also known as Domaine Saint-Lannes and has built a strong reputation beyond France over the years.

Its approximately 70 hectares of vineyards are spread across sunny, south-facing slopes. Clay and limestone soils, combined with good natural drainage, provide favourable conditions for growing healthy and aromatic grapes. Through severe pruning, the family deliberately limits yields to achieve greater concentration. Duffour Père et Fils produces white, red and rosé wines, with freshness and accessibility forming a recognisable thread throughout the range. Modern vinification in stainless steel and careful ageing preserve pure fruit, liveliness and satisfying depth. The wines are excellent with food but equally enjoyable on their own.
