Philipponnat is a Champagne house based in Mareuil-sur-Ay (Marne), one of the most respected independent houses in the appellation. The house is built around a single exceptional terroir: Clos des Goisses, a 5.5-hectare south-facing monopole vineyard on the banks of the Marne at 45-degree slope one of the warmest and most distinctive single sites in Champagne, producing a wine that ages exceptionally well and carries identifiable vineyard character across decades. Philipponnat has farmed this vineyard since 1935.

The Philipponnat range covers the Royale Reserve NV, Rose NV, and Blanc de Noirs alongside the flagship Clos des Goisses vintage expression and its younger sibling, the Clos des Goisses 'le Léon' non-vintage. For on-premise programmes wanting to feature single-vineyard Champagne with a documented terroir narrative a counterpoint to standard house NV blends the Clos des Goisses is one of the most justifiable single-site Champagne stories in the trade. The house's independence and the Mareuil-sur-Ay location (Pinot Noir dominant zone) shape the weight and structure of the range.
