The varieties of olives can be very different in terms of their content of polyphenols.

Some of the best olive varieties for high-quality olive oil with a high polyphenol content are:

  1. Koroneiki: This variety from Greece is known for its high polyphenol content and intense, fruity flavour. Koroneiki olive oil is often green and has a peppery aftertaste.
  2. Picual: Originally from Spain, the Picual olive is one of the most polyphenol-rich varieties. Picual olive oil has a strong, slightly bitter taste and a green colour.
  3. Arbequina: Also from Spain, particularly Catalonia and Aragon, Arbequina olive oil has a moderate polyphenol content. It has a milder taste but is still very healthy.
  4. Frantoio: This Italian variety, particularly common in Tuscany, produces an olive oil with a high polyphenol content and a balanced, fruity aroma.
  5. Leccino: Another Italian variety known for its high-quality oil. Leccino olive oil has a medium to high polyphenol content and a mild yet complex aroma.
  6. Coratina: an Italian variety from Puglia known for its very high polyphenol content. Coratina olive oil is intense and has a sharp, peppery flavour.
