It is of limited and rare production resulting in from the exceptional combination of hard labour and patience of monks with the unique climate of the region. The olives are harvested by hand and carried in sacks and baskets by the monks on their backs to the mules so as to be transported to the oil mill. The trees are watered when it rains since there is only one water spring to fulfill the monks’ needs. The monks have to make supernatural effort for the cultivation of the centuries-old olive trees. Beside that, they have planted many new olive trees in their effort to control the wilderness of the place with the help of our Holy Mother of God.
