Yes, cork comes from the bark of the evergreen oak tree of the genus and species Quercus Suber (oak cork). As such, it is completely biodegradable. Forests of oak cork trees are carefully monitored and cultivated, and act as a renewable source for this remarkable material.
During a harvest, the outer bark of a cork oak’s trunk and major branches is carefully stripped by hand – no mechanical stripping devices are allowed. Experienced cork strippers use a specialized cork axe to slit the outer bark and peel it away from the tree.
A cork tree regenerates its precious outer layer 12 or 13 times during its 150-year lifetime. The first stripping of the cork bark occurs when the tree is between 15 and 20 years of age, with subsequent yields at 9 to 10 year intervals.
