Cork is a material of vegetable origin from the bark of cork oaks, light and with great insulating power. Portugal, with an area of 730 thousand hectares of cork oak, is responsible for more than 50% of the world production of cork.
Cork is extracted from the bark of the cork oak, which can only be removed when the tree reaches 25-30 years of growth, and after that first extraction, only every 9 years.
Cork bark is transported from the South of Portugal, the predominant region of the cork oak, to the North of Portugal, where it is transformed.
Cork goes through a series of stages that differ in terms of the type of cork that is intended to be produced. Natural cork stoppers are manufactured by drilling from a single piece of cork; and technical stoppers are produced from a body formed of agglomerated cork granules, to which natural cork discs can also be applied on the tops.
