Why, and what each one means

We rank olive oil on what a bottle can prove. A harvest year, one named origin and published acidity, peroxide and polyphenols show freshness, and phenol content mattered in a 200-man randomized trial (Covas 2006 (opens in a new tab); our guide). Independent testing carries equal weight, because Mamavation’s lab found phthalates in all but one of 36 oils. Most lab sheets are ordered by the maker, so they score below an outside test.

Freshness & quality 30%
Extra virgin with a harvest year, a named origin and published chemistry (acidity, peroxide value, UV readings, polyphenols).
Independent testing 30%
Highest for tests of the oil you buy by someone the maker does not pay (a consumer group, university or regulator), confirming the grade and clean of contaminants, phthalates included. A certificate the maker orders from an accredited lab scores 3 at most; the maker’s own lab, 2.
Packaging 15%
Dark glass or tin. Plastic or clear glass costs points.
Trust 10%
Highest when the maker names everything, answers questions, and has no recalls, warning letters, Prop 65 notices or lawsuits over safety or labeling. Points come off for unresolved problems and for paid promoters it does not disclose.
Value 15%
Price per liter at the US price a reader pays, against the others here that pass.

Each product scores every one from 1 to 5, and its rating is the weighted average. We list only products rated 3 or above that break none of our rules.

  • A best-by date with no harvest year anywhere, or oil more than about 18 to 24 months past harvest.
  • “Light”, “pure” or plain “olive oil” blends, which are not extra virgin.
  • Clear bottles and plastic jugs.
  • Blends from several countries, or “Mediterranean” oils, with no named origin.
  • “Bio” or “organic” with no certifier or code on the label, and awards as the only evidence: contest panels judge taste, and producers pay to enter.
