One of the premier products of Portugal is obtained from the bark of the cork oak tree and is harvested for a period of about 9 years. Cork is a vegetable tissue and because of its versatility it has had a variety of uses from fishing boats, floor tiles to decorative items and, of course, bottle stops.
Moreover, during the Age of Discovery in the 14th century the Portuguese explorers used cork wood as ship building material. In those days, cork oak wood was referred to as ‘sovaro’ and considered as perfect to withstand harsh weather conditions and the unique quality of never rotting.
