The G4-7-9 Wooden Salt Pepper Miller Grinder is a kitchen tool designed for grinding salt crystals and peppercorns. It is primarily constructed from wood. The grinder features a traditional cylindrical or slightly contoured body with a top knob that is turned to activate the grinding mechanism. Inside, it contains a durable ceramic or stainless steel grinding mechanism that can be adjusted to produce fine to coarse grinds. The ground spices are dispensed from the bottom of the grinder. While used for both salt and pepper, individual grinders are usually dedicated to one spice to avoid flavor contamination.
