From the olive grove to your kitchen table, each bottle of olive oil travels through the extraction process outlined below. While fuller-bodied extra virgin olive oils undergo natural cold-pressing and minimal filtration, lighter tasting olive oils are refined to remove strong taste and create a mild, all-purpose flavor. The more refined the olive oil, the lighter it will be in both taste and color. Follow our infographic to learn how various types of olive oil are extracted, refined and filtrated to create the flavors you love. Today, Bertolli® follows a similar extraction process, using modern machinery instead of the traditional machinery shown in the chart, to deliver quality olive oil in every bottle.
