SILKTOP®

Silktop® are mainly manufactured for entry level wines, which could benefit from short-term aging (three to four years). This is a technically advanced product, properly sealing bottles containing wine of considerable value.

DESCRIPTION
Silktop® technical stoppers, commonly known as 1+1, consist of an agglomerate body made up of cork granules, with a natural cork disk on each end. This product comprises a natural cork face for both the wine and for the consumer while its properties are similar to those of natural cork. There is a consistent sealing, as well as the insertion and the performance of the removal force, TCA results and other sub-sensory aromas combined with a top-level visual appearance.

APPLICATION
Silktop® stoppers are mainly manufactured for medium-class wines, which could benefit from short-term aging (three to four years). This is a technically advanced product, properly sealing bottles containing wine of considerable value. Only food-grade glues are used.

DURABILITY
Silktops® stoppers are recommended for wines that will be enjoyed within 3 to 4 years.
