Extra virgin olive oils — lab polyphenols & purity context
ONSURI Arbequina EVOO, 2025/26 Harvest
Latest 2025/26 Arbequina from ONSURI, with 1,504.42 mg/kg polyphenols and COA / certificate imagery visible on the live product page.
VerdictA current-harvest, lab-certificate-backed oil that now outranks the older Governor podium slots on verified polyphenol strength.
Why it ranks
ONSURI Arbequina earned the third podium slot because the live ONSURI product page now exposes a 2025/26 SKU with 1,504.42 mg/kg polyphenols, product-specific COA/certificate image assets, batch context, and an exact product image from the same page. That is a stronger current ranking case than leaving a lower-polyphenol product in the top three simply because it was previously verified.
Highlights
- 1,504.42 mg/kg polyphenols stated in the live product title and page data
- COA and certificate image assets are exposed on the product page
- Single-varietal Arbequina with current 2025/26 positioning
- Exact product image verified from the official ONSURI product page
- Brand homepage cross-links this SKU and repeats the 1,504.42 mg/kg value
Caveats
- Brand-published page data is stronger than vague marketing, but still not the same as a neutral, independently hosted ranking dataset
- ONSURI has older Arbosana URLs with stale 1,255 mg/kg slugs now showing a newer 651 mg/kg product; avoid reusing old slugs as evidence
- As with all very high-phenolic oils, buy current harvest and use promptly after opening
