Quick answer

A jigger is a double-sided measuring tool that lets you pour exact amounts of spirits, liqueurs, and mixers for consistent cocktails. To use one correctly, hold it level, fill the smaller or larger cup to the rim, then pour slowly into your shaker or glass. For most home bars, a jigger with clear markings and a comfortable grip—like the Wood & Gunmetal Jigger—makes accurate measuring easier than eyeballing.

How to read jigger measurements

Most jiggers have two cups: a smaller one (often 1/2 ounce or 3/4 ounce) and a larger one (typically 1 ounce or 1 1/2 ounces). Some also include internal lines for smaller increments like 1/4 ounce or 1/3 ounce. Always check which side is which before you start pouring. If your jigger has no markings, fill the cup to the top for a full measure. For partial amounts, estimate halfway or use a separate measuring spoon for precision.

Step-by-step: using a jigger without spills

1. Place the jigger on a flat surface or hold it steady at eye level. 2. Pour the ingredient into the correct cup until it reaches the rim or the desired line. 3. Stop pouring as soon as you hit the mark—surface tension will hold the liquid slightly above the rim without overflowing if you pour slowly. 4. Tilt the jigger over your shaker or glass and let the liquid flow out; a gentle tap helps release the last few drops. 5. Rinse or wipe the jigger between different ingredients to avoid flavor transfer.

Jigger vs shot glass: what's the difference?

A shot glass typically holds 1.5 ounces (44 ml) and is designed for drinking straight spirits, not for measuring multiple increments. A jigger offers at least two precise volumes in one tool, often with narrower cups that reduce spillage. For cocktail making, a jigger is more versatile because you can measure 1/2 ounce of lime juice and 2 ounces of whiskey without switching tools. A shot glass works in a pinch, but you'll have less control over partial measures.

Choosing a jigger that fits your bar

Look for a jigger with clear markings, a comfortable grip, and a material that matches your style. Stainless steel is durable and easy to clean; copper or gunmetal finishes add visual warmth but may require hand washing. Consider the capacity you need most: if you often make 2-ounce pours, a jigger with a 2-ounce side saves time. The Wood & Gunmetal Jigger has a wood grip and double-sided gunmetal grey cups, and it is hand wash only—so it's a good fit if you don't mind a little extra care for a distinctive look. The Stranahan's Nosing Glass Set is not a measuring tool, but it's useful for tasting the final cocktail.

Common mistakes to avoid

Don't fill a jigger while it's tilted—you'll get an inaccurate measure. Don't use the same jigger for sticky ingredients like honey or syrup without rinsing; residue throws off later pours. And don't assume all jiggers use the same cup sizes; check yours once and remember the volumes. If you're working with a jigger that has no markings, keep a small conversion chart nearby or measure water once to confirm capacity.

Jigger FAQ

Can I use a jigger for both ounces and milliliters?

Many jiggers list ounces on one side and milliliters on the other, but not all do. Check your specific jigger for markings. If it only shows ounces, you can convert: 1 ounce equals about 30 milliliters. If you often follow recipes in milliliters, look for a jigger with dual markings.

How do I measure a dash or a bar spoon with a jigger?

A dash is roughly 1/8 teaspoon, and a bar spoon is about 1/2 teaspoon (2.5 ml). A standard jigger cannot measure these tiny amounts accurately. Use a dedicated dash bottle or measuring spoons for small increments. Keep a set of measuring spoons on your bar for dashes and bar spoons.

Is a jigger necessary if I already have a cocktail shaker with markings?

Shaker markings are often less precise and can wear off. A separate jigger gives you a clear, repeatable measure and lets you prep multiple ingredients before adding ice. It also reduces the chance of overpouring. A jigger is a small investment that improves consistency, even if your shaker has lines.
