Anyone who has popped open a bottle of wine will agree with George Taber that it is one of the few sounds in the world that brings true joy to the listener. But if the opponents of cork have their way that sound might disappear as Taber a veteran business journalist and author explains in his new book To Cork or Not to Cork: Tradition Romance Science and the Battle for the Wine Bottle (Scribner). As Taber tells it although cork has been used to seal virtually every bottle of wine for nearly three centuries that dominance is now under attack by other forms of closure including screw caps plastic seals and glass stoppers. Taber talks with Knowledge at Wharton about the battle and his book.
