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.
