Why Accurate Measuring Is the Skill That Makes or Breaks a Cocktail
Welcome to Shake, Sip, Serve, your one stop shop for all things bartending.
I’m your host, KAD, and I’ve been slinging drinks and navigating the world of hospitality for over two decades. Over the past fifteen years, I’ve trained new bartenders, corrected bad habits, and rebuilt more cocktails than I can count.
If there is one tool that separates a confident bartender from a guesser, it is the jigger.
In this guide, you will learn what a jigger is, why it matters, how to use it properly, and how accurate measuring directly affects flavour, balance, and responsible service.
What Is a Jigger
A jigger is a bartending measuring tool used to portion liquid ingredients accurately.
Most jiggers are double sided, with a larger measure on one end and a smaller measure on the other. Each side represents a specific volume, allowing bartenders to measure spirits, juices, syrups, and liqueurs precisely.
In Australia, jiggers commonly measure:
- Fifteen millilitres
- Thirty millilitres
- Forty five millilitres
- Sixty millilitres
Accurate measurement is not optional. It is a core bartending skill.
Why Jiggers Matter More Than You Think
Many beginners believe that free pouring is faster or more impressive. In reality, free pouring without training leads to inconsistent drinks and wasted product.
Using a jigger ensures:
- Balanced flavour every time
- Consistency from drink to drink
- Controlled alcohol service
- Reduced over pouring
A cocktail recipe only works when the ratios are respected. The jigger protects those ratios.
How a Jigger Affects the Final Drink
Every cocktail relies on balance.
Adding too much spirit makes a drink harsh.
Too much citrus makes it sharp.
Too much syrup makes it cloying.
The jigger is the tool that keeps everything in harmony.
When drinks taste different each time, the problem is almost always inaccurate measuring.
How to Use a Jigger Properly
Correct jigger technique is simple but important.
Step One
Hold the jigger between your thumb and fingers, not by the rim.
Step Two
Pour the liquid until it reaches the top of the jigger. Aim for a level pour, not a rounded surface.
Step Three
Pour the measured liquid cleanly into the shaker or glass without dripping.
Step Four
Use the correct side every time. Do not guess volumes.
With repetition, this becomes fast and natural.
Common Beginner Mistakes With Jiggers
These mistakes are extremely common.
Under filling the jigger, leading to weak drinks.
Over filling, which throws off balance.
Switching jigger sizes mid recipe.
Ignoring smaller measurements and eyeballing syrups.
Every ingredient matters, especially sweeteners and acids.
Different Types of Jiggers Explained
Not all jiggers are the same.
Japanese Style Jigger
Tall and narrow design that allows precise pouring. Often preferred for accuracy and presentation.
Bell Jigger
Shorter and wider, very common in busy bars. Easy to handle and quick to use.
Graduated Jigger
Marked with internal measurement lines. Useful for beginners learning different ratios.
Any style works as long as you use it consistently.
Measuring for Responsible Service in Australia
Accurate measuring is directly tied to responsible service of alcohol.
In Australia, standard drinks matter. Over pouring can quickly push a cocktail beyond safe serving limits without the guest realising.
Using a jigger helps:
- Maintain legal compliance
- Protect guest safety
- Build trust with customers
Professional bartenders measure because it is responsible, not because they lack skill.
Jigger vs Free Pouring
The Honest Truth
Free pouring is a trained skill that takes time and calibration. It is not something beginners should attempt.
Most professional bartenders still use jiggers, especially for cocktails that require precision.
Speed comes from confidence and repetition, not skipping steps.
How to Choose a Good Jigger
When buying a jigger, look for:
- Clear measurement markings
- Comfortable grip
- Solid weight for stability
- Stainless steel for durability
Avoid novelty jiggers with unclear markings or uneven pours.
Beginner Recommendation
A double sided stainless steel jigger with fifteen and thirty millilitre markings is ideal for beginners.
It covers most cocktail recipes and encourages good habits from day one.
Upgrade Recommendation
For more advanced bartenders, a Japanese style jigger with internal measurement lines offers greater control and precision.
This is a popular choice in cocktail focused bars.
Why the Jigger Is Fundamental to Bartending Technique
The jigger is a core measuring tool used by bartenders at every skill level. Accurate measurement is essential for balance, consistency, and repeatability, making the jigger one of the first tools introduced in bartending education.
Jiggers are widely used because they:
• Establish correct ratios in cocktails
• Reduce variation between drinks
• Support responsible and consistent pouring
They appear in a range of formats, from standard single measures to precision designs and complete bar tool sets. Each variation serves the same purpose: helping the bartender maintain control over flavour and structure.
Understanding the role of the jigger explains why it is considered indispensable in both home and professional bar environments. Accurate measurement builds confidence, reinforces good technique, and forms the foundation of reliable cocktail preparation.

Good bartenders measure. Great bartenders measure well.
