For Peugeot Paris u'Select mills, the grind is adjusted by turning
the ring at the bottom of the mill. Turning the ring in one direction
makes the grind finer, turning in the other makes it coarser. All the
wood used for Peugeot mills are from PEFC-certified European forests.
For use with dry black peppercorns only (do not use with salts, other
spices, or pink peppercorns).
