One of the oldest and prestigious Burgundy domaines, Maison Régnard was established in 1860 by Zéphir Régnard, and is one of the only Chablis wineries that has all its cellars in the historic centre of the town. Bought by Baron Patrick de Ladoucette, of Loire winemaking fame, in 1984, the focus has since been on improving the style and typicity of the wines, which are now found on the best dining tables around the world.

The Maison produces seven of the Chablis Grand Cru (Les Clos, Bourgos, Blanchots, Grenouilles, Preuses, Valmur and Vaudésir), five Chablis Premier Cru (Fourchaume, Montmains, Vaillons, Montée de Tonnerre et Mont de Milieu) and a Chablis and Petit Chablis, as well as exceptional wines such as Le Grand Régnard.

Created in 1992, Le Grand Régnard is a special cuvée designed to reflect the truest expression of the Maison Régnard style each vintage. Similar to the Champagne model, Le Grand Régnard is a blend of 30-year-old vines, with fruit taken from the best parcels of Chablis. The wine is bottled in a traditional 17th century bottle to reflect those used by the ancestors of the family, with a distinctive and unique bulbous shape. A truly individual style of Chablis offering complexity and richness, whilst retaining bright acidity and the purest expression of fruit that the best parcels in the region have to offer.

Chablis is a small appellation located in the northernmost part of Burgundy, in northwestern France. The region sits about 240 kilometers north of the rest of Burgundy's main production areas, positioned closer to Champagne than to the Côte d'Or. This geographic isolation, combined with its cool continental climate, gives Chablis a distinct identity within Burgundy.

The terroir is defined by Kimmeridgian limestone-rich soils, a geological formation that also appears in parts of Champagne. This chalky, fossil-laden soil imparts characteristic minerality to the wines. Chablis produces only white wines from Chardonnay, with a strict classification system: Petit Chablis (the most basic level), Chablis (standard appellation), Premier Cru, and Grand Cru, each with defined vineyard sites. The cool climate means the region's marginal growing conditions create wines with naturally high acidity and modest alcohol levels—traditional winemaking in Chablis often involved aging in stainless steel or neutral vessels rather than new oak, though practices vary among producers.

Chablis whites are renowned for their crisp, mineral-driven character rather than richness or oak influence. The wines typically display citrus, green apple, and flint notes, with Premier Cru and Grand Cru versions showing greater depth and aging potential than basic Chablis. The high acidity provides freshness and food compatibility, particularly with seafood and oysters. The distinction between styles—from lean, unoaked expressions to fuller examples aged in wood—reflects both vintage variation and individual producer philosophy, with many of Chablis' established houses maintaining their own interpretations of the regional character.
