Romain Guiberteau is one of the brightest stars of the Loire, and his reds have become benchmarks for what Cabernet Franc can do in Saumur. Working organically on the limestone (tuffeau) soils around Le Puy-Notre-Dame, he makes wines of unusual purity, structure and finesse — closer to fine Burgundy in feel than to rustic country reds. This is his village Saumur Rouge, 100% Cabernet Franc, the perfect entry into a cult domaine that's notoriously hard to find. In magnum, which ages even more gracefully and is built for the table. A wine collectors chase for good reason.
