What does the term "neat" refer to in beverage service?

The term "neat" specifically refers to a drink that is served straight from the bottle, without any dilution or chilling that occurs from ice. This means the beverage is poured at room temperature, maintaining the pure flavor and characteristics of the spirit or liqueur. This method of serving is particularly common for spirits like whiskey, bourbon, and scotch, as it allows the drinker to fully experience the aroma and taste without interference from chilling or added water that ice would introduce.

In this context, serving a drink using ice, specifying a specific glass, or including a garnish does not align with the definition of "neat." These practices can alter the drinking experience, which is contrary to the intention behind serving a drink neat.
