A walled vineyard owned entirely by one estate—a monopole in the truest sense. The Clos du Château at Château de la Maltroye was hand-cut from solid limestone over 500 years ago, and the Chardonnay vines (approximately 50 years old) occupy 40% of the 2.8-hectare enclosure. Jean-Pierre Cournut, a former aeronautical engineer who took over in 1993, has revitalized this property. The estate spans 15 hectares, 70% classified Premier Cru. The 2020 vintage's crystalline freshness and brisk acidity are ideal for this southeast-facing, limestone-rich site.
