> Is there a ranking of olive oil certifying organizations?

Even skimming, the COOC guidelines look to be more rigorous.

In addition to lab tests (by one of three labs approved by COOC), there's a blind sensory test by olive oil experts, a requirement to print the harvest date on the vessel, and a requirement to print a "best by" date as well.

I understand your desire to find out the quality regardless of the provenance of the olives. But given the rampant fraud in the industry, I just can't see a persuasive argument for speculating about an oil that doesn't pass both certifications in California. Especially when the company in question has the word "California" in its name, more especially when its oil was previously certified by COOC. By the time you figure out the answers to all your questions, we'll be on to the next harvest and the bottle of olive oil you wanted to buy will have gone bad.
