Pinot Noir is probably the most frustrating, and at times infuriating, wine grape in the world. However when it is successful, it can produce some of the most sublime wines known to man. This thin-skinned grape which grows in small, tight bunches performs well on well-drained, deepish limestone based subsoils as are found on Burgundy's Côte d'Or. Pinot Noir is more susceptible than other varieties to over cropping - concentration and varietal character disappear rapidly if yields are excessive and yields as little as 25hl/ha are the norm for some climats of the Côte d`Or.

Clos-Saint-Denis wines are highly esteemed, hailing from a renowned Grand Cru vineyard in the Burgundy wine region of France. Situated in the village of Morey-Saint-Denis within the Côte de Nuits sub-region, these red wines, primarily crafted from Pinot Noir grapes, showcase elegance, refinement, and a harmonious balance of fruit, structure, and complexity.

Jérôme Castagnier is fifth generation, though passage through the female line and sons-in-law has changed the family name: the originator Jules Séguin was succeeded by Albert Rameau then Gilbert Vadey, a military man, who developed the business, working closely with Alexis Lichine. Guy Castagnier, born in Algeria, married Mademoiselle Vadey and began working at the domaine in 1975. Since 2004 the wines have been bottled as Domaine Castagnier. Jérome, the sole son, did not originally intend to join the family business, becoming instead a professional trumpeter, in the Republican Guard. In 2004 he left Paris and the army and came back to Morey-St Denis.
