Natural cork provides unique physical properties that are perfectly suited for preservation and development of fine wine. Cork's intricate cell structure, joined together like minute "honeycombs", creates a material that is compressible, resilient and impervious. These physical properties of cork have not been duplicated by man-made materials.

Natural Cork has the ability to adapt to the vagaries of bottle shape and size. It is equally capable at withstanding environmental changes in heat, cold and moisture. This benefits the wine by protecting against leakage and early oxidation and allows the wine to gain complexity and bouquet throughout its storage life.
