Extra virgin olive oil is good for you thanks to oleic acid and polyphenols, but only if it is clean. Many pesticides used against the olive fly close to harvest pass from the olive into the oil and end up on our plates. Organic farming replaces chemical fertilisers and pesticides with natural substances.
The rules cover every step: growing, milling, where organic olives follow a separate line, and bottling, with standards similar to those for PDO oils. Checks happen in three stages: the certification body inspects the land and tests it in the laboratory and, if all is in order, certifies the field; then it checks the mill and finally the bottling. It takes three years of inspections before the first organic oil can be sold.
Even the label needs special authorisation: it must show the name of the certification body and the words «organic farming». In the end, the label is the oil's certificate of guarantee.
That is why organic oil costs a little more: natural fertilisers and treatments are more expensive and less effective, so each hectare yields less oil, and the inspections have a cost too. For us it is an investment in health and in the land we will leave to those who come after us.
