Located in the village of Parnay along the banks of the Loire, Château Yvonne dates back to the 16th century with its winemaking roots traceable to 1813. In 1997, the estate was acquired by Yvonne (after whom the château is named) and Jean-François Lamunière, who re-established the vineyard with guidance from Françoise Foucault (wife of Charly Foucault from the iconic Clos Rougeard).
In 2007, Mathieu Vallée took over the estate. The son of a winegrower, he gradually expanded it. Today, he tends 19 hectares of vines, 6 planted with white varieties and 13 with red, cultivating Chenin Blanc, Cabernet Franc and Pineau d’Aunis. Organically certified since 1997, the grapes are harvested by hand.
The work in the winery is also very natural, with as little intervention as possible. Fermentation take place using indigenous yeasts and malolactic fermentation is spontaneous. Mathieu Vallée's talent is gradually becoming established given the quality and consistency of his wines, even in difficult years. Château Yvonne has firmly established itself as a reference in Saumur.

Cabernet Franc vines are cultivated on Turonian limestone soils, better known as tuffeau. The berries are manually harvested before being vinified in concrete vats with native yeast for one month. After malolactic fermentation, the wine is aged in turn in barriques for one year, in wooden barrels for six months, then in vats for three months. This single varietal is suitable for 10 to 15 years’ ageing. Austere when young, after some time in the cellar it will reveal delicious aromas of red and black fruit.
