Every year, between mid-May and mid-August, men and women go through the cork oak forests looking for all the cork oak trees with the markings that indicate they are once again ready for their bark to be removed. In nine year cycles, which is the period necessary for the complete regeneration of the Quercus suber. Each of the cork harvester’s movements confirms the expertise, dexterity and skill necessary for this rigorous ancestral process, solely reserved for those who have in-depth knowledge of the practice, technique and expertise that make it possible to perform this specialist work without ever harming the tree. In a ritual that is constantly evolving. There is only one certainty: of returning cycle after cycle.
