An important feature of a pepper mill is the ability to select the grind size and having a consistent grind. To test each pepper mill's grind size, we ground our black peppercorns, starting with a fine grind and working our way to a coarse grind, then repeated the process three times. All of our pepper mills advertise an adjustable grind size.
