Jacques Seysses, a non-native of Burgundy, discovered his true calling in winemaking, a passion inherited from his father, a discerning connoisseur of fine wines. From his youth, Jacques traversed the vineyards of Burgundy alongside his father, forging invaluable connections with esteemed winegrowers. At 25, after gaining experience in the family biscuit business, Jacques embarked on a new path, immersing himself in winemaking under Gérard Potel at Domaine de la Pousse d'Or in Volnay. In 1968, he purchased Domaine Graillet in Morey-Saint-Denis, christening it Domaine Dujac—a playful nod to his name.

Under Jacques's guidance, Domaine Dujac flourished, expanding from its initial 4-hectare vineyard to 11.5 hectares across prestigious appellations such as Clos de la Roche, Clos St-Denis, Bonnes-Mares, Echézeaux, and Charmes-Chambertin. Guided by a philosophy of minimal intervention, Jacques emphasized the importance of natural processes in winemaking, eschewing filtration and fining while aging all premiers and grands crus in 100% new oak.

The domaine's success soared with landmark vintages like 1969, firmly establishing Domaine Dujac's reputation for excellence. In 1973, Jacques married Rosalind Boswell, a Californian who became an integral part of the team, alongside their children Jeremy, Alec, and Paul, who now play key roles in the business. Over the years, Domaine Dujac expanded its holdings, culminating in the acquisition of exceptional vineyards from Domaine Thomas-Moillard in 2005. Embracing sustainable practices, the domaine transitioned to organic farming, with 75% of its premier and grand cru vineyards cultivated organically.

Jacques Seysses's winemaking philosophy emphasizes the inclusion of stems in fermentation, contributing to the wine's complexity and character. In recent years, the cellars in Morey St Denis underwent expansion to enhance cellaring conditions, enabling precise control over fermentation and aging processes. The Clos de la Roche Grand Cru, situated between Morey-Saint-Denis and Gevrey-Chambertin, embodies the terroir's diversity, with varying slopes and soils that shape the wine's distinctive character and elegance.
