Why olive oil? / A practical guide
What are olive oil polyphenols?
Polyphenols are naturally occurring plant compounds in extra virgin olive oil that contribute to flavour and help protect the oil itself from oxidation.
Their amount varies with cultivar, growing conditions, olive ripeness, milling and storage.
Bitterness and pepperiness can accompany oils with phenolic compounds, but taste cannot provide an exact laboratory measurement.
They are an interesting part of EVOO chemistry and flavour, not a licence for exaggerated medical promises.
