Domaine Haut-Marin was founded in 1920 by Swiss explorer-turned-winemaker Jean François Morel, who began with just 10 hectares. Over the past century, the estate has remained in family hands, expanding organically to nearly 300 hectares. Today, siblings Élisabeth and Philippe Morel oversee the domaine. Their flagship wine, Demoiselle de Gascogne, highlights three of the most prominent grape varieties in the Côtes de Gascogne appellation: Colombard, Sauvignon Blanc, and Gros Manseng. Under Élisabeth’s leadership, the estate has achieved HVE Level 3 certification, a testament to its commitment to sustainable viticulture. Chemicals are used sparingly, with a preference for natural solutions to manage pests and frost. The wines are also certified vegan.
