A seasoning mill includes a receiving unit, a grinding unit disposed in the receiving unit, and a closure unit. The closure unit includes a stationary seat having at least one grinding opening, a rotation control seat having a cover wall formed with at least one control opening, and a coupling member for providing a resistive force between a coupling shaft and the rotation control seat such that the rotation control seat is co-rotatable with the coupling shaft relative to the stationary seat from a closed position to an opened position, and that the rotation control seat is capable of being maintained at the opened position when a rotational force exerted thereon is released.
