Guala Closures Australia and O-I, two of Australia's leading packaging suppliers, have announced the launch of the country's first screw-capped sparkling wine bottles for De Bortoli Wines. The new screw-cap closure named Viiva, was developed locally by Guala Closures Australia in response to ongoing complaints from industry and consumers about traditional cork-closed sparkling wines surrounding opening difficulty and loss of carbonation. Guala Closures Australia worked in collaboration with O-I to develop a bottle specifically designed to fit the closure, while maintaining a premium image and key dimensions to match existing filling lines and secondary packaging. The closure system reportedly took five years to develop and significant investment in R&D to ensure it was suited to traditional 5-gas-volume sparkling wines.
