How many counts of vodka are used in a Harvey Wallbanger?

The Harvey Wallbanger is a classic cocktail primarily made with vodka, orange juice, and Galliano. The standard recipe calls for three counts of vodka, making it the correct choice for this question. The "counts" refer to the amount of spirit poured into the glass, with each count typically representing a shot or a standard pour, which in bartending practice is generally about half an ounce.

Using three counts of vodka provides the desired balance of flavors with the other ingredients in the cocktail, ensuring that the vodka's distinct flavor is prominent but not overwhelming when mixed with orange juice and the sweet herbal complexity of Galliano. Each ingredient plays an essential role in the overall character of the drink, and the specified three counts of vodka are essential to achieving a well-balanced Harvey Wallbanger.
