What is a “float” in bartending?

In bartending, a "float" refers to a layering technique for cocktails that involves pouring a liquid over the back of a spoon or down the side of the glass so that it rests on top of another layer without mixing. This technique is often used to create visually striking drinks, demonstrating the skill of the bartender and enhancing the presentation of the cocktail.

For example, a common application of a float would be using a darker liqueur, such as grenadine or blue curaçao, on top of a lighter colored cocktail. The float not only adds complexity to the drink in terms of flavor but also contributes to its aesthetic appeal, drawing the attention of the customer. This method requires precision to achieve distinct layers, showcasing the bartender’s expertise in creating layered effects.

The other options do not capture the essence of a float in the context of bartending. A type of garnish, stirring method, or glassware style do not involve the layering technique that is central to the concept of a float.
