Whats your point? That Cooks is crap, no matter how you label it.
Personally, I dont recall ever asking or being asked for "sparkling wine". It was always "pick up a bottle of Piper" or "grab some Dom", or Pick up some "cheap champagne". Undeducated palates like we have here in America cant tell the difference.
I guess I am an idiot too because I call sparking wine cheap champagne.
Any other Americans use the term "sparkling wine"? Honey, pick up some sparkling wine?
