Where does cork come from?
Cork comes from the bark of the cork oak (Quercus suber), a tree that grows mainly in the Iberian Peninsula. Harvesting is carried out by hand every 9 to 12 years, without ever cutting down the tree. This virtuous cycle preserves biodiversity and actively contributes to the fight against climate change.
By choosing bio-sourced cork, you support a certified supply chain that guarantees:
✅ Sustainable forest management (FSC® / PEFC® / Ecocert®).
✅ Respect for local ecosystems.
✅ Full traceability of the material, from the forest to your bottle.
A respectful harvesting process
Cork harvesting is a demanding craft, passed down from generation to generation. Each plank is carefully removed to preserve the health of the tree. This know-how is at the heart of our collaboration with our Portuguese forestry partners.
🔹 Isabel Ferreira, Quality Manager at J.A.Beira, explains: “We work with producers who value biodiversity and ensure the natural regeneration of the trees.”
Why choose organically sourced cork for your stoppers?
Neutrality and food safety
Bio-sourced cork is free from aggressive chemical treatments. Its neutral organoleptic profile preserves the purity of your spirits, with no risk of undesirable substance migration.
Reduced carbon footprint
Cork oak forests are genuine carbon sinks: each ton of cork produced stores nearly 70 kg of CO₂. By using this material, you help reduce the environmental impact of your packaging.
Enhancing your brand image
Consumers today expect brands to prove their eco-responsible commitment. Choosing organically sourced corks affirms your values of authenticity and sustainability.
