The whole 26 acres of the Domaine de Pialentou is within the Gaillac Appellation. The vineyards surround the cellars and are exclusively planted with grapes from the Appellation.

Red varieties:
- Cabernet Sauvignon and Merlot for the Atlantic touch
- Syrah for Mediterranean style and charm
- Braucol and Duras for the local flavour

White varieties:
- Sauvignon and Mauzac. Two fine grapes with complementary characteristics.

The Domaine de Pialentou owes its fame to its former owner, Jean Louis Ailloud, who came from a long line of winegrowers and tended it for 35 years until 1998, when he sold it to Jean & Kai Gervais, the current owners.
