Cocktail Jigger: The Bartender’s Precision Tool
The cocktail jigger, also known as a cocktail measuring glass, jigger or alcohol measure, is a bar essential. Precise, practical and quick to use, it’s the foundation of every great cocktail. Whether you’re making a Mojito, a Negroni or a Daiquiri, accurate measuring is the key to perfect balance.
But beyond the technique, using a cocktail jigger is above all a gesture of passion. One that guarantees consistent, flavorful and professional cocktails, even at home.

Why Use a Jigger for Cocktails?
The shot glass isn’t the only precise tool behind the bar. The cocktail jigger lets you:
- Master the proportions of each ingredient
- Faithfully reproduce classic or creative recipes
- Avoid waste (syrups, juices, spirits…)
- Ensure smooth service on busy nights, with no guesswork
It’s also a true mark of professionalism. In a bar, it reinforces rigor and a quality image. At home, it impresses your guests with the precision of your technique.
The Different Types of Cocktail Jiggers
There’s a variety of shot glasses and shooter glasses that each play a different role. But when it comes to measuring, three main types stand out:
- Japanese jigger: long and slim, it offers an excellent grip. Accurate to the millilitre. Ideal for sophisticated cocktails.
- Classic US jigger: hourglass shape, very common in bars. Available in 25/50 ml, or 20/40 ml.
- Graduated cocktail measuring glass: often made of glass or clear plastic, with cl or ml markings. Perfect for beginners or syrups.
A little bartender’s tip: keep two jiggers ready on your work surface at all times. One for clear spirits, one for syrups or dark juices. This limits residue mixing.

How to Properly Use a Cocktail Jigger?
Using a cocktail jigger is far more than a simple technical gesture. It’s an art that combines precision, elegance and efficiency. Here are the best practices used by top bartenders:
- Hold the jigger at eye level: this lets you see the exact liquid level for a perfect measurement.
- Pour slowly: a calm motion prevents overflow and improves accuracy.
- Use two fingers to hold it: usually the thumb and index finger, or the index and middle finger, for better stability.
- Position the jigger above the container: shaker, mixing glass or serving glass, to avoid splashes.
- Rinse between each ingredient: a small glass of water lets you quickly clean the jigger and avoid flavor transfer.
- Use two jiggers: one for clear spirits, another for syrups or dark juices. Guaranteed time savings when serving!
Pro Tip:
Experienced bartenders train themselves to pour the right dose without even looking at the markings. But to get there, it starts with measuring rigor. Practice your technique to make the right motion automatic.
Summary:
| Step | Why |
|---|---|
| Eye level | Avoid measuring errors |
| Slow pour | Ensure accuracy |
| Two fingers | Better grip |
| Controlled transfer | Avoid splashes |
| Rinsing | Preserve flavors |
| Two jiggers | Save time |
Bonus: Mistakes to Avoid (and Why)
❌ Not rinsing the jigger between two ingredients
Why it’s a problem: syrup or citrus residue can alter the taste of the next spirits.
Tip: keep a small glass of water nearby to rinse quickly.
❌ Pouring too fast into the jigger
Why it’s a problem: you risk exceeding the dose and throwing off the cocktail’s balance.
Tip: pour slowly, keeping the jigger at eye level.
❌ Underestimating small quantities
Why it’s a problem: 15 ml of lemon or triple sec makes all the difference. Neglecting them will make your cocktail too strong or too bland.
Tip: use a well-graduated jigger and respect all measurements, even the smallest ones.
