Stone Mills Make quot;Better Oilquot;. It's FICTION. The Olive
Many consumers and some producers are convinced that using a stone mill to crush the olives, as opposed to modern, metal crushers, is quot;betterquot;. Stone mills use rollers or wheels, rolled in circles on a slab of granite, to grind the olives into a paste. Mills are sold in different configurations, with two, three, or even four stones.
