Romain Guiberteau has become one of the Loire's most sought-after vignerons, proving that Saumur's limestone soils can produce Cabernet Franc of real seriousness and finesse. Farming organically around Le Puy-Notre-Dame, he works with native yeasts and a light touch to make pure, structured reds that feel more Burgundian than rustic. This is his village Saumur Rouge, 100% Cabernet Franc — the most accessible way into a cult domaine, and a benchmark for the appellation. Drinkable young but with the chalky backbone to age. Hard to find and well worth seeking out.
