We have already talked about the closure of the bottle, about the process that surrounds
it, and, especially, about the materials used. Along with cork, synthetic and natural
stoppers, now a new addition closures the range of Cuatro Rayas’ wines. We are talking
about a cork made from polymers derived from sugar cane.
The new kind of cork provides a high-quality closure, although its main advantage has
to do with the control of oxygen ingress in the bottle. In addition to the oxygen control,
another particular feature is that it is the world’s first virtually zero carbon footprint
closure for fine wines.
Another of the advantages is that this kind of closure doesn’t provide flaws to the wine.
Furthermore, it has an excellent mechanical action in the closure, in other words, it
corks perfectly and keeps good closure conditions, at the very least, for five years. It is
certainly a great innovation in the wine sector that, in this case, benefits from a
vegetable raw material such wonderful as the sugar cane. Environment-friendly,
sustainable, easy-to- uncork and provides all guarantees for wine preservation. These are
the new stoppers that seal the wines of Cuatro Rayas Winery. Could we ask for more?
