Mathieu Vallée has been running Château Yvonne located right in the heart of Saumur Champigny since 2007. Son of a winemaker, Vallée looks after his eleven hectares of vines (three white and eight red) which are divided into 28 parcels and planted with Chenin and Cabernet Franc. Organically certified since 2007, the work in the wine cellar 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. Without doubt this is a domaine to be watched.

Mathieu Vallée produces a very fine single varietal Chenin grown on soils which are typical of the region: tuffeau soils. After harvesting the bunches by hand, the fermentation and ageing is done in barriques. Powerful, stimulating and rich, this white wine can be kept for ten years in the cellar.
