Fill the glass with ice – Start by filling a tall glass (a highball glass works perfectly) with ice cubes. You want it to be nice and cold before pouring in any liquids.

Pour the vodka – Add 1 ½ oz of your favorite vodka over the ice. Feel free to use whatever brand you prefer, but a good-quality vodka will give the cocktail a cleaner taste.

Add the orange juice – Pour in 3 oz of freshly squeezed orange juice. The fresh stuff makes a world of difference, but if you're short on time, a good-quality store-bought juice will do just fine.

Top it with Galliano – Now comes the magic! Slowly float ½ oz of Galliano on top of the drink. This Italian liqueur is what makes the Harvey Wallbanger special—it brings sweet, herbal, and vanilla notes to the cocktail.

Garnish and serve – For a finishing touch, garnish with a slice of orange and a maraschino cherry if you like. It adds a pop of color and a bit of extra flavor to your drink.

Enjoy responsibly – Stir gently and enjoy your Harvey Wallbanger!
