Cork harvesting, also known as stripping, is one of the most environmentally responsible material processes in the world. Unlike many raw materials, cork is collected without cutting down trees.
The Harvesting Cycle
- Bark regenerates every 9–12 years and grows back thicker each time
- Trees can be harvested for more than 200 years
- The first harvest occurs around age 25
The Skill and Tools Behind Cork Harvesting
Cork harvesting relies on specialized hand tools and a high level of expertise developed over many years. Skilled harvesters use a traditional cork axe, designed with a sharp blade and a wedge-shaped handle, to carefully cut and loosen the bark without damaging the living tissue of the tree. This process is central to how cork is harvested without harming the tree and requires precision at every step.
Each movement must follow the natural grain of the bark, using controlled leverage to gently separate it from the trunk. Because improper cuts can affect both tree health and future harvests, this work is typically carried out by trained professionals—many in Portugal, where Portuguese cork is widely regarded as the gold standard. Their expertise combines technical skill with an understanding of tree health, timing, and environmental conditions, helping ensure cork remains one of the most renewable materials available.
A Zero-Harm, Zero-Waste Material
Harvesters remove only the outer bark, leaving the tree intact and thriving. Every piece of cork—even the dust—gets used in manufacturing, from cork leather to flooring to insulation.
Why This Matters to Us
By choosing cork, you support renewable forests, reduce carbon emissions, and help preserve one of the most sustainable ecosystems on Earth.

Frequently Asked Questions About Cork Harvesting
Are cork trees cut down during harvesting?
No. Only the outer bark is removed, and the tree remains alive and continues to grow.
How often is cork harvested?
Cork is typically harvested every 9–12 years once the tree is mature.
What tools are used to harvest cork?
Cork is harvested using a traditional cork axe, a specialized hand tool designed to cut and lift the bark without damaging the tree. Harvesters rely on precise cuts, careful leverage, and years of training to safely remove the bark while keeping the tree healthy.
Why does cork harvesting require skilled workers?
Cork harvesting requires skill because incorrect cuts can harm the tree or reduce future cork quality. Trained harvesters understand how to follow the natural grain of the bark, apply the right amount of force, and work within the tree’s growth cycle.
How long can a cork oak tree live?
Cork oak trees can live for more than 200 years and be harvested many times throughout their lifespan.
Is cork harvesting environmentally friendly?
Yes. Cork harvesting supports renewable forestry, biodiversity, and carbon absorption. In fact, studies have also shown that cork oak trees that are regularly harvested live longer on average than those that aren’t, much like a rose bush that thrives with regular pruning.
Why does cork harvesting matter to consumers?
Choosing cork supports sustainable land use and responsible material sourcing without permanent environmental damage.
