Champagne Cork Stoppers
This type of stopper consists in a body of agglomerated cork and two discs of natural cork in one edge.
The agglomerated cork body is designed for optimum elasticity and long-term sealing capacity, assuring that the pressure inside the bottle is always constant and maintained. At the same time, the natural cork discs (rotated against each other to completely close the cells of the natural cork material) make sure the drink inside the bottle only have contact with natural cork of high quality.
Originated by a renewable raw material source with the capacity of being recycled, makes this an environment friendly product, ecological and sustainable.
