The plastic cork is one of several alternatives to natural cork. Some like it and some do not. Some producers refuse to put plastic in their bottles. While others think it is an excellent alternative for relatively simple wines that are sold to consumers who still want to open their bottles with a corkscrew.
The biggest producer of synthetic corks, Nomacorc, will soon launch an alternative cork that is made with plant based polymers instead of oil based. Nomacorc thinks there is a demand for such a cork that combines the environmentally friendly aspects of the natural cork with the reliability of the plastic cork. They also hope that this new cork will be able to appeal to organic growers.
However, it has been very difficult technically to make this new “natural cork”. Due to these difficulties the cork will not (yet?) be totally made from plants.
The new cork will be launched later this spring. Read more about it here www.thedrinksbusiness.com
