The harvested olives are cleaned and selected manually, removing leaves and twigs and then placed in airy boxes away from the sun and heat, waiting to be sent to the mill at the end of the day. Once they arrive at the mill, the olives are first washed carefully with small jets of water, in order to remove all the impurities and then be sent to the cold extraction process which will allow for a product that will then be placed in special sanitized stainless steel containers, waiting to be subjected to withdrawals and checks required by the PDO Umbria Regulations.
