Pressing Olive Oil The Traditional Way: Into the Grinder
A Traditional Olive Press: Into the Grinder
© Kyle Phillips, Licensed to About.Com
Traditional olive presses employ grindstones to grind the olives, reducing them to a paste from which the oil can be extracted. Unlike the grindstones of a mill, which are horizontally mounted, with one turning atop the other, the grindstones of an olive press are vertically mounted and rotate in a tub, crushing the olives against the floor of the tub.
