Neighbouring Sancerre, between Burgundy and Berry, the Pouilly-Fume vineyard covers 1,245 ha, only of Sauvignon Blanc. Limestone soils and marl with small oysters from Kimmeridgien bring to the smoky and fruity aromas of these Loire Valley wine a mineral flinty note, and the best white wines produced can age for several decades, thanks to their beautiful acidity. The main producers are Alexandre Bain, Didier Dagueneau, Ladoucette (Chateau du Nozet), Chateau de Tracy.
