Galliano is traditionally added to a Harvey Wallbanger cocktail.
The classic drink consists of vodka, orange juice and a float of Galliano, a tall golden Italian liqueur flavored with herbs, anise and vanilla. Galliano’s distinctive bottle and bright color make it easy to recognize, while its sweet herbal character separates the Harvey Wallbanger from a simple vodka-and-orange combination.
The cocktail became widely popular in the United States during the 1960s. Its exact origin story is disputed, although advertising helped establish the colorful character of “Harvey” and the drink’s memorable name. The Harvey Wallbanger is sometimes confused with a Screwdriver; both contain vodka and orange juice, but only the Harvey Wallbanger traditionally includes Galliano. The liqueur is usually floated on top rather than fully shaken into the drink.
