Bourbon Root Beer Float

Bourbon over ice topped with root beer and whipped cream — the spirit's vanilla and caramel from oak aging pair naturally with the soda's own spice character.

The Bourbon Root Beer Float is an adult elaboration of one of the American soda fountain's most enduring creations. The ice cream soda — carbonated water with a scoop of ice cream — is generally credited to Philadelphia confectioner Robert McCay Green, who improvised the combination in 1874 during a public demonstration when he ran out of cream for a flavored soda and substituted vanilla ice cream instead. Root beer floats — using the distinctively American root beer soft drink made from sassafras, wintergreen, vanilla, and other botanicals — developed as a specific variation through the late 19th century, with Frank J. Wisner of Cripple Creek, Colorado credited with a version he called the Black Cow in 1893. The A&W Root Beer chain, founded by Roy Allen in 1919 in Lodi, California, helped make the root beer float a national staple of American drive-in and diner culture through the 20th century. Bourbon's natural barrel-derived flavor compounds — vanillin from new charred oak, caramelized sugar notes from toasted stave, coconut and peach lactones from the wood — share the same aromatic family as root beer's vanilla-and-spice profile, making the pairing a genuinely coherent flavor combination rather than a novelty. The spirit's warmth and the ice cream's cold richness together create a drink that is simultaneously both things it references: a proper bourbon cocktail and an ice cream dessert.
