Olio d’oliva, were made in a frantoio ‘oil mill’
Olives were pressed by huge macine ‘millstone’
In many places they still produce olio extravergine d’oliva in the traditional way.
The first oil produced right after la raccolta delle olive, is called olio nuovo ‘new oil’.
In several Italian regions famous for their oil production, many frantoi open their doors to the public, and offer free samples of olio nuovo
In Umbria for instance “Frantoi aperti” is a very popular annual event
