Winery Château Yvonne

The castle has stood for centuries, with vineyards historically surrounding Parnay; the modern vineyard was restored in the late 1990s and, in 2007, Mathieu Vallée took over management, retaining the name Château Yvonne and developing the production of historic cuvées such as Yvonne Blanc and Yvonne Rouge.

The estate practices organic farming and, according to several sources, follows biodynamic principles and low‑intervention winemaking methods: hand‑harvesting, indigenous yeasts, limited use of sulfites and little or no filtration/fining. The approach aims to express the terroir naturally.

Located in Parnay, within the Saumur and Saumur‑Champigny appellations, with a terroir of limestone/tuffeau and parcels spread across several small plots around the village and on the 'Côte' that slopes down to the Loire.
