What is the purpose of a jigger in bartending?

A jigger is a vital tool for bartenders that serves the specific function of measuring liquor accurately. This precision is crucial in bartending for several reasons.

First, using a jigger helps maintain the consistency of cocktail recipes, ensuring that each drink tastes the same regardless of when or by whom it is made. This is particularly important in a busy bar environment where multiple drinks may be served at once.

Second, accurate measurements assist in managing inventory effectively. By knowing exactly how much liquor is served in each drink, bartenders can track usage and reduce waste, which is essential for profitability.

Lastly, properly measured drinks contribute to responsible alcohol service, helping to prevent over-serving customers and promoting safe drinking practices.

While mixing drinks, serving drinks, and shaking cocktails are all important aspects of bartending, they do not pertain to the specific function of a jigger, which is designated solely for measuring.
