Due to the extreme rarity of its wines—and the fact that its pure Cabernet Francs may be the world’s greatest—Clos Rougeard has become the Loire Valley’s ultimate cult producer.

Its red trophies, Poyeux and Bourg, are now among the world’s most coveted wines, while its towering white, Brézé, is nearly as ardently sought after. Not only do they come from three of the most extraordinary terroirs in France; they represent the winemaking of two brothers who are among France’s most gifted, Nady and Charly Foucault.

But with the passing of Charly in December, 2015, and the subsequent sale of the domaine two years later, the eight-generation-old Foucault family domaine in Saumur came to an end. And the wines have become scarce to the point of being virtually unobtainable.
