Natural cork stoppers


A one piece cork stopper, pressed from natural cork plate. Quality grades are Extra, Super, 1st class and 2nd class, and depend on the number of pores per individual piece. Produced mainly in 24mm diameter, but 22mm stoppers are also available for ice and other special wines offered in smaller bottles. Lengths of 38, 45 and 49mm are available, and be supplied fully or partly washed.

This stopper does not limit wine storage time, which will depend mainly on wine characteristics and on conditions of storage.
