How Are Wine Corks Made

Cork is derived from the bark of Quercus suber, also known as the cork oak tree. These evergreens, the majority of which grow in Portugal and Spain, are abundant and strictly protected. Cork oaks regenerate their outer layer of bark, which allows them to be harvested about once every decade.

Is cork environmentally friendly?

Cork is a natural, environmentally friendly material. It biodegrades completely and can be easily recycled without producing any toxic residues. The plastic portion of screw caps is non-recyclable. Cork forests – or ‘montados’ in Portuguese – rank among the top biodiversity hotspots in the Mediterranean and Europe.
