What is a "jigger" used for?

A "jigger" is a crucial tool in bartending specifically designed for measuring spirits and mixers accurately. This device typically has two sides, with each side representing different measurement volumes, such as one ounce and half an ounce. The use of a jigger ensures that cocktails are mixed to the correct proportions, which is essential for consistency and balance in flavor. Precise measurements can greatly impact the taste and quality of a drink, making the jigger an indispensable instrument in both professional and home bars.

Other options, while related to various aspects of bartending, do not accurately describe the function of a jigger. For instance, a stirring device is used to mix drinks, garnishing tools enhance presentation but do not measure, and cooling devices may chill drinks or glasses but have no role in measuring ingredients. This specificity of function is what makes the jigger vital to the art and science of crafting cocktails.
