Why do you only recommend COOC certified oils? What does the seal mean?
The vast majority of olive oil certifications are more of a pledge by the manufacturer and some have a taste (sensory) certification. As a scientist, I need more assurance than this. I recommend consuming olive oils that are certified by the California Olive Oil Council (COOC). COOC-certification is the only approval within the U.S. that includes mandatory chemical analysis of the oil by third-party laboratories and their standards are among the strictest worldwide.
