What is a "float" in cocktail-making?

A "float" in cocktail-making refers to the technique of layering a spirit on top of another ingredient, usually a cocktail or a mixer. This is often achieved by carefully pouring the spirit over the back of a spoon or down the side of the glass, which allows the denser liquid to sit atop the lighter liquid without mixing. This technique adds visual appeal and can create distinct layers in the drink, enhancing the presentation and allowing for different flavors to be experienced as the drink is consumed.

In contrast, blending ingredients together typically refers to mixing or shaking them to achieve a uniform consistency, which is not what a float involves. Shaking and straining are methods used to prepare drinks, but they do not involve the layering effect characteristic of a float. Serving a drink over ice is a common practice for many cocktails but is unrelated to the specific technique of floating a spirit.
