Loire valley is a primarily white-wine region that stretches over a long distance along the Loire River in central and western France, and where grape varieties and wine styles vary along the river. Four sub-regions are situated along the river:
Upper Loire is known for its Sauvignon blanc, producing wines such as Sancerre AOC, but also consisting of several VDQS areas;
Touraine produces cold climate-styled white wines (dry, sweet or sparkling) from Chenin blanc in Vouvray AOC and red wines from Cabernet Franc in Bourgueil AOC and Chinon AOC;
Anjou-Saumur is similar to the Tourain wines with respect to varieties, but the dry Savennières AOC and sweet Coteaux du Layon AOC are often more powerful than their upstream neighbours. Saumur AOC and Saumur-Champigny AOC provides reds; and
Pays Nantais is situated closest to the Atlantic, and Muscadet AOC produces white wines from the Melon de Bourgogne grape.
