This technical cork stopper is made up of a granulated body, obtained by individual moulding, to which are added two natural cork discs, which act as a protective barrier in contact with the wine.
The Spark® Top II stopper undergoes two technological cleaning processes. ROSA for the cork granules and CorkNova for the discs, which ensure a stopper with excellent performance, capable of guaranteeing the evolution of sparkling wine in the bottle over decades.
