Perséis, in the domaine's Greek mythology, is the daughter of Ocean and the beloved of Helios, a daughter of the West and of the setting sun. The wine is pure Vermentino from clay and limestone soils at Montady, where the vines sit between the Canal du Midi and the Oppidum d'Ensérune. In 2024 the grapes were harvested by machine at aromatic maturity, picked for freshness rather than weight. A slow, gentle pressing extracts only the cleanest fruity juice, which is then separated from its solids and fermented cool in tank to protect the aromatics. The finished white is bright and tense at just 12% alcohol: citrus on the nose, an attack full of energy, a mineral, mouth-watering middle and a long finish on grapefruit.
