Let's just decipher the name. Sauvion is the winery, Muscadet is the wine named after the region but the grape in the glass is Melon de Bourgogne. Sound confusing. Muscadet Sevre et-Maine is one of the best appellations in the Loire Valley's Pays Nantais region. In fact it's considered the home of of the Melon de Bourgogne even though it originated in Burgundy it's no longer planted there. It is the second most grape planted in the Loire Valley. It is called Muscadet after the appellation but what is in the bottle is the Melon de Bourgogne grape.
House Sauvion is located in the vineyard Nantais at Castle Cleray-Sauvion in Aeolian. It was acquired by Ernest Sauvion in 1935 and is one of the oldest properties in the Sevre et Maine. Today it is run by Pierre-Jean Sauvion's son of Yves Sauvion who has studied at the University of Bordeaux and in all the major corners of the world. He returned home to the Castle Cleray-Sauvion in 2004.
