Legend has it that on a hot day in 1874 flavored-soda vendor Robert M. Green ran out of ice. He used quick wits and vanilla ice cream to keep his soda cold, creating the first ice cream soda. However, it wasn't until 1893 that Frank J. Wisner thought to pour root beer over ice cream, but his float was still missing something. Edward Barq solved the puzzle in 1898. The New Orleans chemist crafted his signature Barq's Root Beer. Known for its unique and sharp taste, Barq's was the missing ingredient to the perfectly refreshing, crisp root beer float.
