Not surprisingly, New World wineries have more openly embraced twist-off closures than Old World producers, who still rely heavily on cork for sealing their bottles.
Much of what defines New World winegrowing relies on advances in technology, and while wine closures are less about technology, they reflect a mindset among vintners that recognizes the shortcomings of corks as well as the viability of their alternatives.
According to our statistics based on wines reviewed in 2012 by Wine Spectator editors, 91 percent of New Zealand's wines were bottled under twist-off, followed by Australia (67 percent), Oregon (23 percent), Argentina (14 percent), Washington (12 percent) and California (8 percent).
