A revolutionary new re-sealable top for sparkling wine has been launched by Tesco. The supermarket giant claims the ‘Zork’ top will allow customers to enjoy a glass of sparkling wine, and keep the rest of the bottle for another day, without having to worry about it losing its fizz. Dan Jago, Tesco’s Beer Wines and Spirits Category Director said, “This is great news for customers who are just looking to enjoy the odd glass of sparkling wine as Zork keeps the bubbles in the bottle for more than a week. And because the bottle can now be perfectly re-sealed we believe the innovation will introduce more people to sparkling wine.
