Earlier quoted context omitted.
The North American Olive Oil Association maintains a list of genuine olive oils. They send people into grocery stores to randomly buy a bottle of one of the listed brands/varieties and test it in their lab. https://www.aboutoliveoil.org/64-certified-pure-and-authenti...
Is this one of those schisms like exists between USDA organic and California organic? Because your list doesn't include any olive oils I would actually eat, whereas they are all on this list: https://cooc.com/certified-oils/
> “In 2010, the UC Davis Olive Center, an organization created to promote the sale of California olive oil, published a report funded by California olive oil producers and companies. The purpose of the report was to make news that would discredit their competition – imported olive oils.”

So it seems like these two organizations are at odds with each other. But the California study was based on subjective “taste tests” to identify fake olive oils… Big red flag there.
