The Harvey Wallbanger is a variant of the Screwdriver, created in 1969 by the McKesson Imports Company, which enjoyed popularity in the 1970s. This cocktail benefits from using freshly squeezed orange juice.
Fill a highball glass with ice cubes.
Add the vodka and enough freshly squeezed orange juice to almost fill the glass.
Float Galliano L'Autentico on top and garnish with an orange wheel and maraschino cherry.
