Cork's elasticity, impermeability, and chemical stability means that it seals the bottle without contaminating the wine, even when it must mature for many years. The Romans also used cork for the soles of shoes and for floats for fishing nets.

Here's a peek into how corks are made. First, a ​cork harvester carefully strips the cork bark from the tree. ​Then the cork bark dries out on pallets for several months. After drying, the cork goes into stainless steel tanks where it is submerged in water to be rinsed, cleaned and re-hydrated.

Its versatility is undoubtedly a key factor contributing to its extensive usage in different domains. Cork stands as a natural resource of immense value for Portugal, not only economically but also environmentally and culturally. Its sustainable production and versatility make it a unique material admired worldwide.

It is a completely natural raw material, with unique properties which give it an unrivalled character. It is light, impermeable to liquids and gases, elastic and compressible, provides thermal and acoustic insulation, it is a fire retardant and highly abrasion-resistant.
