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.
