Scott Tribe makes the case for Vernor's ginger ale being the finest ginger ale in the world.
Scott Tribe is right.
Wikipedia states that "Vernors is the oldest surviving ginger ale sold in the United States...[dating back to] 1866."
It is primarily available in Detroit, Ohio, Michigan, Chicago, Southern Ontario and Florida but, for example, in Ottawa, Ontario, Farm Boy carries it.
The finest.
