Coteaux du Loir is an area around the river Loir, a tributary of the Loire, in the far north of the greater Loire wine region, producing dry or medium dry white wines, rosé and red wines. This vineyard, classified AOC on 12 May 1948, consists of only 70 hectares in 16 communes of Sarthe and 6 of Indre-et-Loire. The sharp, straw-yellow white wines are made with white Pineau Blanc de la Loire (Chenin Blanc), while the sharp, spicy red wines which predominate, occasionally the product of barrel fermentation, are made from the Gamay grape or from Cabernet or Côt. The rosé wines are made with those added to Grolleau grapes. In good years the local Pineau d'Aunis grape is used to make a varietal wine.
