How to Shake a Cocktail Properly

Shaking is not theatre. It does three jobs at once: it chills the drink, melts a controlled amount of ice into it, and whips in tiny air bubbles that give citrus and egg drinks their lively texture. Get those three right and a basic sour tastes far better.

This guide covers when a drink should be shaken instead of stirred, how long to shake, what kind of ice to use, and the most common mistakes that make shaken drinks thin, warm or cloudy with ice chips.

Why shaking changes a drink

When ice hits liquid in a closed tin, heat moves from the drink into the ice and some of the ice melts. The violent movement speeds this up, so a shaken drink gets colder and more diluted in seconds than a stirred one does in half a minute.

Shaking also traps small air bubbles. In a sour or a drink with pineapple juice, egg white or aquafaba, those bubbles create a light foam and a softer texture. In a spirit-only drink such as a Manhattan, the same bubbles make the drink look cloudy and feel less silky, which is why those drinks are stirred.

When to shake and when to stir

The simplest rule: if anything opaque or acidic goes in, shake it. Juices, syrups with fruit purée, cream, egg and liqueurs with heavy texture need the force of a shake to combine fully.

Stir drinks that are clear and spirit-forward. A Martini, Negroni or Old Fashioned should feel weighty and smooth, and stirring chills them while keeping that texture.

• Shake: Daiquiri, Margarita, Whiskey Sour, Cosmopolitan, Espresso Martini
• Stir: Martini, Manhattan, Negroni, Old Fashioned, Sazerac
• Build in the glass: highballs such as a Gin and Tonic or Paloma with soda

Choosing ice

Use plenty of ice: fill the shaker about two-thirds full. Too little ice melts quickly and leaves the drink warm and watery. Ice straight from the freezer is drier and colder than ice that has sat out; wet ice brings extra water with it.

Standard 2.5 to 3 cm cubes are ideal. Crushed ice dilutes very quickly and is better saved for swizzles and juleps. One large cube shaken alone, sometimes called a whip shake, adds texture with less dilution and suits drinks served over crushed ice.

How to shake, step by step

Build the ingredients in the smaller tin or glass first, cheapest ingredients first, so a mistake costs less. Add ice to the larger tin, put the small tin on top at a slight angle and tap it to seal.

Hold the shaker with both hands, one on each end, with the small tin facing you. Shake hard in a straight line or a slight arc over your shoulder for 10 to 12 seconds. The tin should frost over and be uncomfortable to hold. To open a Boston shaker, strike the large tin firmly where the seal is tight, near the top edge.

• Use about 10 seconds for drinks served over fresh ice
• Use 12 to 15 seconds for drinks served up in a chilled coupe
• Strain immediately; a shaken drink keeps diluting while it sits on ice

Dry shakes for egg white and aquafaba

Egg white and aquafaba foam best without ice first. Shake all ingredients without ice for about 10 seconds to build the foam, then add ice and shake again to chill. A reverse dry shake (shake with ice, strain out the ice, then shake again without it) gives an even denser foam.

Raw egg white carries a small risk of Salmonella. Pasteurized egg whites from a carton or aquafaba are safer options for anyone who is pregnant, elderly, very young or has a weakened immune system.

Common shaking mistakes

Most problems come from ice and timing. A drink that tastes thin was usually shaken with wet or too little ice, or left to sit before straining. A drink that tastes hot and sharp was under-shaken and is not diluted enough.

• Shaking a spirit-only drink: it turns cloudy and loses its silky texture
• Adding carbonated mixers to the shaker: the pressure can force the tins apart
• Reusing shaker ice for a second round: it is already wet and partly melted
• Skipping the fine strainer for drinks served up: ice shards keep diluting the drink

Common questions

Can I shake a cocktail without a shaker?

Yes. A clean jar with a tight lid works well. Fill it two-thirds with ice, shake for 10 to 12 seconds and strain through a small sieve. Avoid thin glass containers that could crack from the cold and impact.

Is a Boston shaker better than a cobbler shaker?

A two-tin Boston shaker holds more ice, seals reliably and is easier to clean, which is why most bars use one. A three-piece cobbler shaker has a built-in strainer and is convenient at home, but its small cap can stick when cold.

How much water does shaking add?

For a typical sour, shaking adds roughly a quarter of the drink's starting volume as water. The exact amount depends on ice size, temperature and shake length, so keep your method consistent.
