The Famous Grouse

Whilst we were talking about what gifts to bring to China, Holly suggested the Famous Grouse.  Then I said, for comedic effect, "those unfamiliar with the brand might say, 'What is that chicken doing on the label?'"
Holly laughed, and corrected me, "It's a pheasant!"
I thought, "Surely it is a grouse...."  But British politely dictates that one cannot correct another's stupid mistake.
