The life cycle of cork nine years from harvest to harvest.
Cork is in fact the outer bark of the cork oak, which is grown commercially in a narrow belt stretching through Portugal, Spain and the South of France and along the North African coast.
The bark is stripped only in summer and the first stripping must wait until the tree is about twenty years old. Subsequent strippings take place every nine or ten years. This makes cork an ecologically acceptable product, as it is one of the few materials, which regenerates itself.
