our materials: cork

Why we love cork

Cork is naturally light, elastic, resilient and highly impermeable - famously so to liquids like wine - even the ancient Greeks and Romans used cork to stopper containers! 

Cork's bubble-form structure and natural fire retardancy also make it very suitable for acoustic and thermal insulation and a great alternative to petrochemical-based insulation products.

It is made from the bark of cork oak (Quercus suber) trees and is 100% biodegradable and renewable.

Cork oak forests are a major carbon sink, helping to preserve biodiversity and combating desertification alongside providing renewable sources of materials for products. 

Making cork

The Quercus suber tree is native to southwest Europe and northwest Africa. Our cork is sourced from Portugal, which is home to 34% of the world’s cork forests and accounts for 50% of the annual harvest.  

Cork bark is harvested for the first time when the tree is 25 years old, and then removed every 9-12 years without ever damaging the tree, which lives around 200 years. 

The traditional method of harvesting cork without machinery is still in practice today - expert 'extractors' lever the bark away from the tree using axes, it is then left to dry in planks before being processed in to products.

Re-use and recycle

If you no longer want your cork stopper, we suggest you cut it up and grind it into a fine mulch. Then add it to the soil of your house plants to help them retain moisture. It's a trick used by Orchid growers and great for those of us who forget to water!
