It’s from near Saint-Emilion, and made very much in a classic Saint-Emilion style. The importer says:
Chateau Mayne de Valence is for Old World wine lovers! This wine was made in the purest traditions of saint-Emilion. On the nose, it delivers a wonderful bouquet of wild berries with hints of grass and a slight refreshing earthiness. On the palate, the tannins are smooth and well-integrated. This is a gastronomy wine to pair with red meat, poultry and cheese.
