Château Pierre-Bise works the steep slopes of the Middle Loire, where Chenin Blanc thrives in cool continental conditions. The winery's portfolio centers on the Coteaux du Layon and Quarts de Chaume appellations—two of France's most distinguished sweet wine terroirs. Its flagship Quarts de Chaume Grand Cru, a botrytis-affected Chenin Blanc, has drawn attention from Wine Spectator, Wine Advocate, Wine Enthusiast, and Decanter. The Coteaux du Layon 1er Cru 'Chaume' and L'Ouche Coteaux du Layon 'Chaume' round out the core range, each expressing the mineral tension and honeyed complexity that define the region's best expressions. Chenin Blanc in these appellations develops remarkable aging potential, its natural acidity and noble rot character creating wines of both immediate appeal and long-term structure.
