Is your olive oil 100 percent olive oil? Is it extra virgin olive oil? This is not that complicated. You don’t need a doctor named after a wizard or even a refrigerator.
If you want to know that your olive oil is 100 percent extra virgin, buy it from a producer of 100 percent extra virgin olive oil. Most of the world does not have that option. Everyone in Yolo County does.
