The University of California - Davis conducted a study to see whether or not those olive oils labelled "extra virgin" truly were. The startling results can be read here. To sum them up, up to 69% of imported extra virgin olive oils are fraudulently labelled.
When I found this out, I had to know if my Terra Delyssa extra virgin olive oil was true or not. On Crunchy Betty, she reveals a quick trick to find out for yourself at home. Pour a small amount of your oil into a container, and cover it. Place this in the fridge for 24-48 hours. When you remove it, you will have your results. Crystallization means it is extra virgin, a solidified lump means it is not.
The Terra Delyssa fraud has solidified while our new Kirkland organic has only crystallized.
Here is a concise list of the discovered truthful and fraudulent oils. See where your olive oil ranks. If it's not there, try the test at home.
