Being in the wine business, this is a question I get asked on a daily basis and have had some difficulty responding to without adding more confusion to the consumer. Whatever the end result, the cork has tradition and romance behind it and will be an industry challenge to change the perception of the screwcap in the eyes of the consumer.I’ve relied on these sources to help guide me:“TO CORK OR NOT TO CORK”, written by George M. Taber, author of “Judgement of Paris“ – an in-depth review of the most controversial topic in the world of wine: What product should be used to seal a bottle? Should it be cork, plastic. glass, a screwcap, or some other type of closure still to be invented?http://www.azom.com/details.asp?ArticleID=2535 - discusses the reasons for the shift and all other options currently available today.
