Virgin Olive Oil Virgin means the oil was made by simply pressing olives.
It didn't undergo any of the industrial processes used to make 'refined' oils such as canola, sunflower, soybean and the lower grades of olive oil labeled 'Pure,' 'Light,' and simply 'Olive Oil.' Virgin olive oils that have no taste defects and pass strict tests in terms of chemistry can be labeled 'Extra Virgin.' Virgin olive oils that have modest taste defects and meets somewhat less strict chemical parameters are labeled 'Virgin.'
Unfortunately, you don't see 'Virgin' oils for sale because too often producers market 'Virgin' oils as 'Extra Virgin' to command higher prices. Until standards enforcement catches up with the practice, real 'Extra Virgin' will be hard to come by.
