There are many benefits to freshly grinding pepper, salt, herbs and spices for cooking and seasoning. A quality mill with a specifically designed grinding mechanism will release the aromas and essential oils of that spice. Another advantage of using freshly ground spices or minerals (salts) is the control a mill provides for determining the coarseness (size) of a grind. A high quality pepper, salt or spice mill gives you the ability to choose and change the coarseness according to taste or necessity.
