How Long to Shake a Cocktail (and How to Know)

How long to shake a cocktail? For most drinks, shake hard for about 10 to 15 seconds with a full tin of good cubes. You know the shake is done when the outside of the tin is covered in frost and is too cold to hold for long. The seconds are a guide. The frost and the feel are the proof.

This is a detail inside the bigger skill of shaking, stirring and building. For the full picture, read our cocktail technique guide.

The short answer

Shake hard for 10 to 15 seconds.
Use cubes, filled well above the level of the liquid.
Stop when the tin is frosted and very cold.
Strain at once. Ice left in the drink keeps melting.

Shake with your whole arm, not your wrist. A hard, fast shake with the tin moving a long way is better than a long, lazy one.

What the seconds are doing: chill, dilute, aerate

A shake does three jobs at once.

Chill. Ice pulls heat out of the liquid. A cold drink tastes cleaner and sharper.
Dilute. As ice melts, water goes into the drink. That water is an ingredient. It softens alcohol, opens flavour and makes the drink easier to sip. Too little and the drink is hot and harsh. Too much and it is thin. For more on this, see how much water shaking adds to a cocktail.
Aerate. Tiny bubbles of air mix into the liquid, which gives citrus drinks a lighter, livelier texture.

Shaking does all three faster than stirring does. That is why drinks with juice, cream or egg are shaken, and spirit-only drinks are usually stirred. If you are not sure which to pick, read shaken versus stirred and which cocktails need which.

Ice size changes the count

The number of seconds depends on the ice.

Large, dense cubes: melt slowly. They need the full 12 to 15 seconds.
Small or wet cubes: melt fast. Ten seconds may be enough, and fifteen may leave the drink thin.
Crushed ice or slush: melts almost at once. Shake for a very short time or do not shake at all. Use cubes whenever you can.
Old ice from the freezer that smells: can taint the drink. Use clean, fresh ice.

Fill the tin with ice to the top if you can. More ice means less air, and less air means less crashing around and less melting. A half-empty tin makes a weak, watery drink because the ice breaks into pieces.

Up versus on the rocks

Where the drink goes after the shake changes how long you should shake it.

Served up (in a coupe, with no ice): the drink has no more ice to melt in the glass. Shake until the dilution is right, usually the full 12 to 15 seconds.
Served on the rocks: the ice in the glass will keep melting. Shake a little less, around 10 seconds, and pour over fresh ice, not the used ice from the tin.

Never pour the used ice from the tin into the glass. It is already cracked and wet.

Example: a Daiquiri shaken three ways

Say you make three Daiquiris with the same recipe: 60 ml (2 oz) white rum, 25 ml (0.75 oz) lime juice, 15 ml (0.5 oz) sugar syrup. You use cubes and shake each for a different time.

5 seconds: the glass is cool but not cold. It tastes hot with alcohol, and the lime and sugar sit apart.
12 seconds: the tin is frosted. The drink is cold and tastes round. The lime, sugar and rum have joined.
30 seconds: the tin is white with frost but the drink tastes thin and flat. The ice has over-diluted it.

The middle one is the Daiquiri you want. Taste your own versions a few times and your arm will learn the count.

When this does not work

If the tin does not frost, your ice may be wet or your tin warm. Chill the tin first and use drier ice.
If the drink is watery every time, you probably shake too long or use too little ice.
If a drink has egg white, cream or fruit pulp, it may need a dry shake first. The track below covers that.
A badly sealed tin leaks. Seal it firmly and keep the tin pointed away from guests.
Serve to adults of legal drinking age and encourage slow, responsible drinking.

Learn this in five minutes

The Mixologix track "The Hard Shake" teaches why shaking chills, dilutes and aerates together, how to grip and shake for the right number of seconds, and how to fill with cubes rather than slush. Each lesson takes five minutes and ends with a drink you can make tonight.
