Classic, timeless lines for this fully transparent grinder. 18cm 7" To get the best results, we recommend you to use only dry, hard, whole peppercorns that are 5 mm (1/4?) or less in diameter. Black, white and dry green peppercorns can be ground in Peugeot pepper mills. The pink berries can be ground only if in a blend (max 15% pink) with one of these other peppercorns. Dried coriander seeds is also suitable for the pepper mechanism.
