In southern Portugal, particularly across the Alentejo region, the countryside is dotted with cork oak trees. Their trunks may look rough and deeply grooved, but the material they provide is familiar to people all over the world.

Cork.

Most of us know it as the stopper in a bottle. Far fewer know the careful work involved in harvesting it.

Skilled workers remove the outer bark by hand, using specialised axes and years of experience. The task requires a steady hand: cut too deeply and the living layer beneath can be damaged. Done properly, the tree remains standing and grows another layer of cork.

The bark is not harvested every year. After a harvest, the tree needs time to regenerate, with successive harvests generally separated by nine years. A cork oak can continue producing cork over a long life.

In the Alentejo, cork trees are part of a wider landscape known as the montado. Cork and holm oaks grow among pastureland and cultivated fields, supporting farming and providing habitat for wildlife. This landscape has been shaped by generations of people who have learnt to work with the trees rather than simply clear the land.

There is something extraordinary about a material that can be gathered without felling the tree that produces it. Yet the process is not effortless or automatic. The knowledge of when and how to harvest must be passed from experienced workers to the next generation.

Portugal is the world’s leading cork producer, and the craft remains part of its rural identity.

The next time you see a cork stopper, remember that it began as living bark on a tree that may still be growing in the Portuguese countryside.

Some of the most useful things we make come not from conquering nature, but from learning how to work with it.
