Cork is made of cork oak, which has a history of more than 6000 years. It grows along the Mediterranean coast. Its bark can be simply processed into cork. The cork made of this material has high elasticity, strong water absorption and good air permeability. It has a strong ability of self recovery, and can recover quickly even after high pressure. Cork has a very high position in the wine industry. From ancient times to now, it seems that there is no second cork that is more suitable for making wine.
However, when tasting wine, cork will convey more information to us, such as winery, year and place of production, which should be consistent with the wine label. The bottom of the cork of a well preserved wine should be wet. Otherwise, if there is a crack and it is too dry, it will prove that it is not properly preserved. Moreover, the deteriorated wine can be smelled through the cork.
