Patient Cottat works Sauvignon Blanc in Sancerre and across the Upper Loire, where chalky soils and cool continental air shape wines of mineral precision. The winery's Pouilly-Fumé Anciennes Vignes and Sancerre Anciennes Vignes—both from old vines—have drawn attention from Wine Spectator, Wine Advocate, and Wine Enthusiast. These are expressions of terroir-driven winemaking in a region where Sauvignon Blanc reaches its most structured and age-worthy form. The Sancerre Vieilles Vigne rounds out the portfolio, offering another window into how mature vineyards translate limestone and flint into wine of depth and complexity.
