Olive Oil Review Expanded: Many Do Not Make the Grade

We tested three new olive oils based on reader requests, and the results are in! Our new tests included two olive oils that claim to be high in polyphenols, and the results were surprising:

-- One olive oil was rated so poorly by our professional taster it was considered to be "lampante" -- i.e., not fit for human consumption.

-- The other high-polyphenol oil delivered a good amount of polyphenols, rated well for taste, and is now our new Top Pick for a very high-polyphenol olive oil.

We also tested California Olive Ranch Global Blend but were somewhat disappointed.

See the results now for 13 popular olive oils in our updated Extra Virgin Olive Oil Review.
