The California Olive Ranch (COR) is a large U.S. producer of extra virgin olive oil. Its Artois, Calif., orchard sits on approximately 1,400 acres in the Sacramento Valley, but the company processes a total of approximately 13,000 acres of orchards.
Within hours of being harvested the olives are sent to COR’s state-of-the-art facility in Artois where they are milled — generally a process of washing the olives, grinding them into a paste, and then separating the oil from solids and water.
After the olives are milled and the oil is extracted some of it is bottled immediately and marketed as a fresh specialty oil. The rest of it is “racked,” a process of storing the oil in large steel tanks to let the remaining organic matter settle out similar to that in the wine industry.
