A Whiskey Highball is a simple and refreshing cocktail made by mixing whiskey with a carbonated beverage, typically soda water or ginger ale. The drink is served over ice in a tall glass, allowing the flavors to blend while maintaining a crisp and effervescent quality. This cocktail is popular for its versatility, as it can be made with various types of whiskey, including bourbon, rye, or scotch. The highball format emphasizes the whiskey's character while the mixer adds a lightness, making it an ideal choice for casual gatherings or warm weather.
