Château d'Aydie is a wine estate that extends over 58 hectares, including 49 hectares in AOP Madiran and 9 hectares in AOP Pacherenc-du-Vic-Bilh. The Madiran vineyard is composed mainly of Tannat, complemented by Cabernet Franc, Cabernet Sauvignon and Fer Servadou. The Pacherenc-du-Vic-Bilh vineyard is planted with local grape varieties (Petit Manseng, Gros Manseng, Arrufiac and Petit Courbu).

The estate produces a dozen cuvées on a wide variety of terroirs: pebble soils on the high slopes, gravel soils composed of pebbles, quartz sands and clays, clay-limestone soils and boulbène soils on the lower slopes.

It was created in 1927 by Frédéric Laplace, who gave the vine a prominent place in the estate, which was oriented towards polyculture. In 1952, Pierre Laplace succeeded his father and ten years later, marketed the wines bottled at the estate for the first time. In 1975, Tannat's first production was born on the clay-limestone soils of the Madiran and then in 1982, the Laplace family acquired the château, a villa of Belle-époque architecture overlooking a hillside and having belonged to the Béarnais writer Joseph Peyré, winner of the Prix Goncourt in 1935.
