Highest Polyphenol Extra Virgin Olive Oil

Finding. OlioWise applies this label when the latest listed release records more than 500 mg/kg (or equivalent metric) total phenols. These oils often have a more pronounced bitter and peppery character.

Method. The label uses the catalog's latest-release total-phenol field rather than a ranking of every historical test. Analytical methods have not been harmonised across producers.

Limitation. A total-phenol result is a chemistry descriptor, not proof that an oil qualifies for the EU-authorised olive-oil polyphenol wording. That assessment requires the relevant hydroxytyrosol-plus-derivatives measurement. This listing does not duplicate pooled catalog figures, which change as records are added.

For current pooled catalog figures, methods, and observation lists, see the recorded olive oil chemistry report.
