Guala Closures Australia and Owens-Illinois (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 glass manufacturer 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 research and development to ensure it was suited to traditional 5-gas-volume sparkling wines.??De Bortoli Wines has applied the closure to its Trevi range (pictured).
