Périgord Walnut Oil Pressing

Huilerie de Noix du Périgord

The pressing of walnut oil from Périgord walnuts (Juglans regia — AOP Noix du Périgord) in traditional stone-mill operations. The process involves lightly roasting the walnut kernels, grinding them to a paste on a stone mill, pressing the paste in a hydraulic or screw press, and allowing the oil to settle without filtration. The unfiltered, slightly cloudy result is the defining quality marker of traditional Périgord walnut oil.
