Shaken vs stirred cocktails: when to shake, when to stir, ice and dilution

TUREFF• •0

Shaking and stirring do the same three jobs: they mix the ingredients, chill them and add water from melting ice. What differs is how much air they add and how the finished drink feels. Once you know the rule of thumb, you will rarely need to look it up.

The rule of thumb

Shake drinks that contain citrus juice, other juices, dairy, egg white or thick syrups.
Stir drinks made only of spirits, vermouth, liqueurs and bitters.

A Daiquiri, Margarita or Whisky Sour is shaken. A Martini, Manhattan, Negroni or Old Fashioned is stirred.

Why shaking suits citrus drinks

Shaking hard with ice whips tiny air bubbles into the drink and breaks the ice into fragments, which chill it fast. Juice and syrup need that vigorous mixing to combine properly, and the light, slightly frothy texture makes a sour drink feel brighter. Shaking also clouds a drink, which does not matter when it has juice in it.

Why stirring suits spirit-only drinks

A drink made only of clear spirits and fortified wines should look clear and feel silky and weighty on the tongue. Stirring chills and dilutes gently without adding air, so the drink stays glassy. Shaking a Martini is not wrong, and some people prefer it, but it will be cloudier, colder at first, a little more diluted and lighter in texture.

Dilution is part of the recipe

Water from the ice is not a flaw; it is what makes a cocktail drinkable. A spirit-forward drink straight from the bottle tastes hot and harsh, and a sour without enough water tastes sharp. Most recipes assume the drink will gain a meaningful amount of volume from melted ice. That is why technique matters:

Too little shaking or stirring: the drink is warm, strong and unbalanced.
Too much: it turns thin and watery.

How to shake

Build the drink in the smaller half of the shaker, cheapest ingredients first, so a mistake costs less.
Fill the tin about two-thirds with fresh, solid ice.
Seal it, hold both halves firmly, and shake hard for around 10 to 15 seconds, until the outside of the tin is very cold and frosted.
Strain at once, so the drink stops diluting.

For drinks with egg white, many people shake once without ice (a "dry shake") to build foam, then again with ice. If you use raw egg, choose fresh eggs from a reliable source, or use pasteurised egg white.

How to stir

Add the ingredients to a mixing glass, then fill it with ice.
Slide the back of a bar spoon down the inside of the glass and turn it smoothly so the ice spins as one mass, without clattering.
Stir for around 20 to 30 seconds, then taste a drop on the back of the spoon. It should be cold and smooth without tasting watery.
Strain into a chilled glass.

Ice and straining

Use dry, hard ice straight from the freezer. Wet, half-melted ice dilutes too quickly.
A Hawthorne strainer over a shaker tin holds back the ice.
Double straining through a fine mesh strainer as well catches ice shards and bits of fruit or herbs, which matters for drinks served without ice.
A julep strainer, the perforated spoon-shaped one, sits inside a mixing glass for stirred drinks.
For drinks served on the rocks, strain over fresh ice rather than the ice you shook with, which is already broken up and melting.

A note on balance

Whatever the method, taste before you pour. If a drink is too sharp, a little more syrup fixes it; too sweet, a little more citrus. And because well-made cocktails hide their strength, keep count and pace yourself. Do you shake your Martini or stir it? Tell us which you prefer and why in the comments.
