What does the term "neat" indicate when ordering a drink?

The term "neat" indicates that a drink, typically a spirit like whiskey or vodka, is served straight from the bottle without any additional ingredients, ice, or mixers. This preparation allows the drinker to fully experience the flavor and characteristics of the spirit as intended by the distiller. Drinking it neat highlights the nuances of the alcohol, as it is at room temperature, providing an unadulterated tasting experience.

In contrast, serving a drink with ice cubes dilutes the spirit and changes its flavor profile. Mixing with soda adds additional flavors and alters the original taste, while a splash of water, although sometimes used to open up the spirit's aroma and flavor, does not align with the definition of neat, which implies a purist approach to enjoying the drink.
