The term 'NEAT' is a term used to describe a drink that is served without ice or mixers. It is usually used to refer to a spirit, such as whiskey, vodka, or rum, that is served at room temperature or slightly chilled. NEAT drinks are often served in a rocks glass, which is a short tumbler with a wide mouth. NEAT drinks are popular among connoisseurs of spirits, as they allow the full flavor of the spirit to be experienced without any dilution from ice or mixers.
