In the world's largest producer of Cork – Portugal, harvesting season starting from May, until the end of June. Harvest time, the workers carefully stripped Cork oak (an oak wood deciduous trees, bark, soft and flexible "Cork" developed) Cork, not too deep, otherwise the tree will die back due to inability to resist the parasite. After each harvest, take 9 years to the same strains of Quercus variabilis upon taking the Cork. A healthy tree Quercus variabilis is 200 years, stripping up to 18 times.
2. Cork stripping down in the open air. Good summer sun to dry Cork in the water; continuous rain in the fall and clean Cork contains tannins. In the jargon, this day is called the Cork "stable" for up to six months, longer in danger of mildew.
