The first closure without the risk of TCA contamination (the annoying cork smell) and without glue in contact with the wine, is called Sughera. It is realized by Labrenta, a vanguard company in the research on wine closures, after a ten-year process crowned with a patent (n. 1424843 del 3.10.2016). Sughera is a micro-agglomerated closure, perfectly sterilized, tied without glue. The innovation consists of a special blend of pharmaceutical polymer that is a natural tie between cork micro-grain. Wine producers can now offer a purer closure at sensorial and organoleptic level, completely recyclable. Another innovation that perfects Sughera is a sophisticated process of micro-injections that permits to repeat the tradition and naturality of cork. On the surface are created particular grooves for a final effect very similar to natural cork, not only for a visual impact but also for touch.
