This is an affordable, solid, natural wine bottle cork with greater porosity that has undergone a set of transformations similar to but very different from colmating that gives it a much superior visual appearance to any agglomerated cork and better aging characteristics. The colmate (coating) process of this natural cork/stopper uses cutting edge, environmentally friendly water based technology to create a first rate sealant. This is truly an incredibly attractive and functional wine cork at an unbelievably affordable price.
