In a sense, the advent of polymer stoppers has enabled winemakers for the first time to precisely control and understand the ageing of their products. What is the magic of polymer plugs, which can make the complete control of the aging situation that winemakers have dared not even dream of for thousands of years.
This depends on the superior physical properties of polymer stoppers compared to traditional natural cork stoppers:
The polymer synthetic plug is composed of its core and outer layer.
The plug core adopts the world’s mixed extrusion foaming technology. The fully automatic production process can ensure that each polymer synthetic plug has a highly consistent density, microporous structure and specification, which is very similar to the structure of natural cork plugs. Observed through a microscope , you can see uniform and closely connected micropores, which are almost the same as the structure of natural cork, and have a stable oxygen permeability. Through repeated experiments and advanced production technology, the oxygen transmission rate is guaranteed to be 0.27mg/ months, to ensure the normal breathing of the wine, to promote the wine to mature slowly, so that the wine becomes more mellow. This is the key to preventing wine oxidation and ensuring wine quality.
It is because of this stable oxygen permeability that the millennia-long dream of winemakers has become a reality.
