The root beer float was allegedly invented in 1893 by Frank J. Wisner, a Colorado gold mine owner, who was inspired by the snowy peaks of Cow Mountain. He added a scoop of vanilla ice cream to his root beer, creating the first "Black Cow." National Root Beer Float Day is celebrated annually on August 6th.
The exact origins of National Root Beer Float Day are unclear, but the day is celebrated on August 6th each year. The root beer float itself has a storied history: it was reportedly invented in 1893 by Frank J. Wisner, a Colorado gold mine owner, who was inspired by the snow-capped Cow Mountain. Wisner added a scoop of vanilla ice cream to his root beer, creating what he called a "Black Cow." The treat quickly gained popularity at soda fountains across the United States. National Root Beer Float Day was likely established by root beer brands or ice cream companies to promote this classic summertime dessert.
Over the years, the root beer float has evolved from a simple soda fountain treat to a versatile dessert with variations using different ice cream flavors (e.g., chocolate, strawberry) and alternative sodas (e.g., birch beer, cream soda). Today, National Root Beer Float Day is celebrated with promotions at restaurants like A&W, which often offers free or discounted root beer floats. Home celebrations also involve making floats with craft root beers and artisanal ice creams. Social media campaigns and local events help keep the tradition alive.
