Look for a harvest date on the bottle and do not buy an olive oil without one.
Top four recommended from the analysis:
4 Red Island Australian extra virgin olive oil
3 Heraclea Food Co extra virgin olive oil from Greece
2 Bragg extra virgin olive oil
1 Paolo Parisi Organic extra virgin olive oil
None of these are an industrial approximation of real food.
