Noix du Périgord are early or dry walnuts or walnut kernels with a fine texture and a unique taste similar to black walnuts, produced in the French regions of Aveyron, Charente, Corréze, Dordogne, Lot and Lot-et-Garonne, where the walnuts must be grown, shelled and packed.
Early walnuts are fresh and sold in their shells and the nuts are white with a thin skin that can be easily peeled. Dry walnuts are gently dried and less bitter than early walnuts and the walnut kernels are small, light or dark in color and must be minimally 8 mm in size.
