What type of glass is preferred for serving a Golden Cadillac cocktail?

The preferred glass for serving a Golden Cadillac cocktail is a Fiesta glass. A Fiesta glass typically has a wide bowl and a longer stem, which enhances the presentation of the cocktail and helps to maintain the drink's temperature. This style of glass is well-suited for mixed cocktails, allowing the drinker to savor both the aroma and flavor of the beverage.

When serving cocktails like the Golden Cadillac, which is a creamy, dessert-style drink made with ingredients such as Galliano, cream, and crème de cacao, the choice of glass can greatly impact the drinking experience. A Fiesta glass allows for the visually appealing presentation of the cocktail's rich colors, making it more inviting.

Other glass types mentioned, such as an old-fashioned glass, tall cooler glass, or shot glass, do not provide the same aesthetic or functional benefits for a drink like the Golden Cadillac. Each of these alternatives is designed for different types of beverages— the old-fashioned glass is typically used for straight spirits or cocktails served over ice; the tall cooler glass is suited for refreshing, longer drinks; and the shot glass is meant for holding smaller, concentrated servings of spirits. Thus, the Fiesta glass is the most appropriate choice for this particular cocktail.
