What makes an olive oil extra virgin and what does not

Draft. This piece will explain what separates extra virgin from plain olive oil: how the oil is extracted, what the tasting panel is looking for and why acidity does not tell you what most people think it does.

It will go through what the health claims authorised in the European Union actually say about olive oil and its polyphenols, with the exact wording and a link to the regulation.

Before it is published, every source and every study it cites will be checked against the original.
