Myths Unmasked

Koroneiki olives from the Mani Peninsula produce a chemically distinct oil from Arbequina or Leccino. The cultivar sets the polyphenol ceiling. Harvest timing determines how close the oil gets to it. Extra virgin is a grade, not a marketing synonym for "cold pressed." To qualify, the oil must meet chemical limits (including free acidity at or below 0.8%, peroxide value, and UV K-values) and pass a sensory panel for defects and positive attributes. The grade still does not require cultivar disclosure, harvest-date labeling, or published lab polyphenol results. Le Maniot is 100% Koroneiki, single estate, third-party lab certified. Napoleon, Le Maniot's food scientist, times the Mani pick for early-window fruit and documents grove-to-bottle practice so harvest timing stays tied to the grassy, peppery profile buyers expect from this estate.

Smoke point is not a fixed property of olive oil. It depends on free fatty acid content and polyphenol stability. Low-quality oils with high free acidity smoke early. Le Maniot's free acidity is below 0.3%. Its smoke point is approximately 400F. That threshold clears sauteing, roasting, and pan searing. The myth originated with low-grade oils. It does not apply to certified extra virgin oil from a controlled harvest.

Oxidation is the mechanism. Light, heat, and oxygen accelerate it. Dark glass and a cool pantry slow it significantly. The harvest date sets the clock. Most supermarket olive oil shows a best-by date without a harvest year. You do not know when the clock started. Le Maniot labels its harvest vintage on every bottle. Store it away from heat and light. It remains stable well within the vintage window.

Broker laundering blends lower-grade oils with minimal certified oil and sells the result under a premium origin label. Under EU olive-oil origin rules (Commission Implementing Regulation (EU) No 29/2012), the relevant place is where the olives were harvested and the oil was extracted, not a bottling address alone. US / CBP origin analysis is a separate framework (substantial transformation) and is not a substitute for reading harvest and mill location on a single-estate label. Published university and lab surveys have repeatedly found imported bottles that failed chemical or sensory extra virgin checks in blind testing; treat "imported" as logistics, not proof. Single-estate verification removes the broker entirely. Le Maniot comes from one grove, one family, one peninsula. The estate is named on the label.

The EFSA threshold is a regulatory standard, not a marketing category. It requires a minimum of 250 mg/kg hydroxytyrosol and its derivatives to qualify for a documented health claim. Le Maniot publishes harvest measurements and HPLC / ISO methodology on the Lab Report page, with the PDF certificate available on request. Napoleon, Le Maniot's food scientist, reviews the testing protocol for each documented harvest. A polyphenol number without an accredited lab certificate is a claim. With one, it is a documented fact.
