The walnut tree is to the banks of the Dordogne what the olive tree is to Provence: an unmistakable symbol, part of the heritage of the landscape.
The walnut tree has also been a source of wealth since the 10th century, when peasant farmers used to pay their debts in bushels of walnuts. In the Dordogne valley, a Great Tourist Site, walnut trees form a soft, leafy cushion between the river and its cliffs. Standing in neat rows, they are part of the Noix du Périgord AOC that includes parts of the départements of Dordogne, Corrèze and Charente.
Marbot, Corne, Grandjean and Franquette are the four varieties that share this AOC, in their early, dried or shelled forms. Walnuts are also a delicacy from which oil and liqueurs are produced.
The Périgord walnut has held AOC status since 2002.
