About National Black Cow Day
National Black Cow Day is celebrated every year on 10 June, falling on a Wednesday in 2026. The day honours the black cow, a simple but much-loved American drink made by adding a scoop of vanilla ice cream to a glass of root beer. Better known today as a root beer float, it is a nostalgic soda-fountain treat that has been cooling people down since the late 19th century.
How to Celebrate National Black Cow Day
The black cow is one of the easiest treats to make at home, which makes this an effortless day to enjoy. Here are eight ways to take part.
- Make the classic black cow – Pour chilled root beer over one or two scoops of vanilla ice cream in a tall glass and watch the foam rise. It is ready in seconds.
- Use proper root beer – Seek out a craft or traditional root beer with a strong sassafras and vanilla flavour for the most authentic taste.
- Chill your glass first – A frosted mug keeps the float colder for longer and adds to the old-fashioned soda-fountain feel.
- Experiment with flavours – Swap root beer for cola to make a brown cow, or try cream soda or sarsaparilla for a different twist.
- Add a topping – A swirl of whipped cream and a cherry turns a simple float into a proper dessert.
- Host a float bar – Set out different sodas and ice creams and let guests build their own. It is a hit with children and adults alike.
- Visit a soda fountain or diner – Many classic American diners still serve floats. Support a local one and enjoy the drink in its natural home.
- Share your float online – Post a photo of your fizzing creation and encourage friends to make their own.
What is National Black Cow Day?
National Black Cow Day is an unofficial American food holiday celebrating the black cow, a beverage made from root beer and vanilla ice cream. The name is interchangeable with root beer float, though some regard the black cow as the original. The day appeals to anyone with a sweet tooth and a fondness for nostalgic soda-fountain treats, and its early summer timing makes the cold, fizzy drink especially welcome.
When is National Black Cow Day?
National Black Cow Day falls on 10 June every year. In 2026 that is a Wednesday. The date is fixed and does not change from year to year.
The History of National Black Cow Day
The drink at the heart of this day has a well-told origin story. Frank J. Wisner of Cripple Creek, Colorado, is credited with inventing the black cow in August 1893. Wisner owned the Cripple Creek Cow Mountain Gold Mining Company and ran a bar that produced its own soda, including a popular root beer called Myers Avenue Red.
According to the story, one evening Wisner looked out of his window and saw the full moon shining on the snow-capped peak of Cow Mountain. The image reminded him of a scoop of vanilla ice cream. Inspired, he hurried back to his bar and dropped a spoonful of vanilla ice cream into the children’s favourite root beer. He named the result the Black Cow Mountain, which the local children soon shortened to simply black cow.
The treat spread quickly and became a fixture of American soda fountains throughout the 20th century. The closely related root beer float now has its own observance on 6 August, but National Black Cow Day in June keeps the original name alive and gives the drink an extra moment in the early summer sun.

Why National Black Cow Day Matters
The black cow is a small slice of American culinary history, born in a mining town and kept alive at soda fountains for more than a century. Celebrating it preserves a piece of that heritage, supports the independent diners and soda makers who still serve it, and gives families a cheap, fun treat to share. If you enjoy fizzy nostalgia, you might also like National Stewart’s Root Beer Day later in the month.
