“The Spiked Wallbanger Coffee is a modern variation of the classic Harvey Wallbanger, created by bartender Donato "Duke" Antone in 1952. The original Harvey Wallbanger became a cultural phenomenon in the 1970s thanks to marketing campaigns by George Bednar. This coffee variation, sometimes called a "Dirty Wallbanger," emerged as coffee cocktails gained popularity, replacing the original's orange juice with high-quality cold brew for a more sophisticated, energizing twist.”
