What is the primary use of a jigger in bartending?

The primary use of a jigger in bartending is to measure spirits accurately. This tool is essential for ensuring that cocktails maintain a consistent flavor and balance, which relies heavily on precise measurements of each ingredient, particularly the alcoholic components. Bartenders use jiggers to pour fixed volumes, typically in ounces or milliliters, allowing them to create drinks that adhere to standardized recipes. Accurate measurements help in maintaining the integrity of the cocktails and ensuring that customers receive the intended taste experience.

Measuring spirits correctly also plays a crucial role in managing inventory and controlling costs in a bar setting. By using a jigger, bartenders can prevent over-pouring and minimize waste, ensuring that each drink is both delicious and profitable.
