What type of glass is used for serving a Colorado Bulldog?

A Colorado Bulldog is typically served in a highball glass. This type of glass is characterized by its tall and slender shape, which is ideal for cocktails that contain carbonated mixers as it allows for a good mix while accommodating ice. The highball glass can hold a significant volume, making it suitable for the Colorado Bulldog, which is a combination of vodka, coffee liqueur, cream, and cola.

Using a highball glass also enhances the drink's presentation, showcasing the layering of ingredients and the effect of the cola topping. The other types of glasses typically serve different kinds of drinks; for instance, a martini glass is designed for cocktails served straight up, a rocks glass is better suited for spirits served neat or with a small amount of mixer, and a pint glass is generally for beer. Thus, the highball glass is the most fitting choice for serving this particular cocktail.
