Philipponnat is a 40-acre estate in the commune of Mareuil-sur-Ay. It is owned and operated by the same family that founded it. The estate is noteworthy for one reason because until the late 1970s it was the only Champagne estate making single-vineyard wine. Robert M. Parker Jr. has written this: “The wine from this historically important Champagne house that continues to make it worth talking about is the profound and notoriously age worthy Clos des Goisses, a blend of Chardonnay and Pinot Noir from a dramatically steep site along the Aisne-Marne Canal.”
