(n.) An imprecise measurement used to indicate a very small amount of liquid, most often used in reference to liquids that are used sparingly, such as bitters or hot sauce. In a cocktail recipe, the term is used to indicate what comes out with one shake of the bottle, though this amount can vary wildly from bottle to bottle, to even each shake. Some bartenders advocate for a more accurate measurement, using eye-droppers or standardized shaker bottles.
