Improved wine caskPenfolds Wines patented an improved wine cask they called the ‘Tablecask’, designed like a barrel lying on its side, with a plastic, air-tight tap. Unfortunately, the tap leaked, and the product was soon abandoned. Wynn’s perfected the wine cask in 1970, with a tap that was exposed by tearing away a panel on the front of the box. The new design offered extra convenience for drinkers and “chateau cardboard” helped to make wine an everyday drink.  Orlando’s Coolabah  wine cask, launched in 1973,  became famous with the advertising campaign “Where do you hide your Coolabah?”
