November Polyphenols: Lab-Certificate

Discover below the Certificate of Polyphenols Analysis received by the specialised independent labs for NOVEMBER Polyphenols early harvest olive oil as per the analysis of October/November 2025 harvest.

Understanding Our Polyphenol Levels:

Every harvest, our oil is independently tested and certified for its polyphenol content — and we publish those results transparently so you know exactly what you're getting. The figure shown represents the polyphenol level at the time of certification, captured at peak freshness.

Like all living compounds, polyphenols gradually decline over time through natural oxidation. This process is accelerated by exposure to light, heat, or air. Once your bottle is opened oxidation is accelerated - To protect your oil and get the most from every drop, we recommend storing it in a cool, dark place — away from the stove or windowsill — and consuming it within 4–6 weeks of opening.
