In the ’70s, disco music ruled the airwaves and, on television, Charlie’s Angels solved crimes without messing up their perfectly feathered bangs. Leisure suits, platform shoes, and bell bottoms were in fashion. Fondue, salad molds, and pigs-in-a-blanket were staples at parties. Cocktails like the Tequila Sunrise, Rusty Nail, and Piña Colada were all rage in the ’70s, but none were as popular as the ubiquitous Harvey Wallbanger, known as the decade’s signature drink. A Harvey Wallbanger is essentially a Screwdriver (orange juice and vodka) with a float of Galliano®, an Italian herbal liqueur made with 30 different spices.
