For the classic, skip the fruit purée and blender

A classic Daiquiri is white rum, fresh lime, and sugar shaken cold and strained into a chilled glass. It is clear and brisk, with lime first and rum close behind—not a pink strawberry slush.

It is worth making if you like bright sours and a clear rum character. If you want a sweet fruit slush or a long low-alcohol drink, choose another recipe before buying a full bottle of rum.

Make the first one at 60:20:15

Use 60 ml (2 oz) white rum, 20 ml (2/3 oz) fresh lime juice, and 15 ml (1/2 oz) 1:1 simple syrup. “1:1” means equal weights of sugar and water—for example, 50 g of each, stirred until dissolved and cooled.

Chill the glass. Add all three ingredients to a shaker, fill it with firm ice, and shake until the outside feels thoroughly cold, usually 10-12 seconds. Strain straight into the chilled glass; the classic is served without ice.

If the first sip feels harsh, check temperature

A warm glass, half-filled shaker, or very short shake can make the drink feel hot and hard. On the next one, chill the glass, fill the shaker with ice, and shake until cold before adding more sugar.

If it is sour or sweet, change only the syrup next time

If it is sharply sour, raise the 1:1 syrup from 15 ml to 20 ml. If each sip gets sweeter and stickier, reduce it to 10 ml and check that you did not use rich 2:1 syrup—two parts sugar to one part water.

Lime acidity changes from day to day, so 60:20:15 is a starting point for the first drink. Note whether it was too sour, too sweet, or not cold enough, then change only one thing in the next Daiquiri.

Ingredients

  • 60 ml (2 oz) white rum
  • 20 ml (2/3 oz) fresh lime juice
  • 15 ml (1/2 oz) 1:1 simple syrup
  • A full shaker of firm ice
  • Optional thin lime wheel

Tools

  • Cocktail shaker or a safe, tightly sealed jar
  • Jigger or small measuring cup
  • Strainer
  • Chilled coupe or small cocktail glass

Method

  1. Chill the serving glass. Ice water works if freezer space is limited.
  2. Add rum, fresh lime juice, and simple syrup to the shaker.
  3. Fill the shaker with firm ice and shake for about 10-12 seconds, until thoroughly cold.
  4. Strain into the chilled glass and serve without ice.
  5. Identify whether the drink is too sour, too sweet, or simply too warm before changing the next batch.
Use what you have
  • No simple syrup: use two bar spoons superfine sugar and dissolve it in the lime juice before shaking, following the IBA direction.
  • Using rich 2:1 syrup: start with 8-10 ml (about 2 tsp).
  • No lime: lemon makes a rum sour, but it does not fully reproduce a classic Daiquiri.
  • No shaker: use a sturdy, leakproof jar and open it away from your face.
  • Want zero proof: build a separate tea- or cane-based sour; removing the rum does not leave a classic Daiquiri.
If the result is off
  • Too sour: the lime may be unusually sharp. Increase 1:1 syrup by 5 ml (1 tsp) next time.
  • Too sweet: reduce syrup by 5 ml and check whether you used rich 2:1 syrup.
  • Harsh and hot: chill the glass, use enough firm ice, and shake to proper temperature before adding more sugar.
  • Thin and watery: avoid wet crushed ice, stop shaking once cold, and serve immediately.
  • Sugar crystals remain: dissolve superfine sugar in lime before adding ice, or use 1:1 simple syrup.
Cost and effort

Roughly US$2-6 per serving, mostly depending on the rum.

FAQ

What is the classic Daiquiri ratio?

The current IBA specification uses 60 ml white Cuban rum, 20 ml fresh lime juice, and two bar spoons superfine sugar. A practical home baseline is 60:20:15 with 1:1 simple syrup.

Is a Daiquiri always frozen and strawberry flavored?

No. The classic is a clear shaken rum sour served up. Frozen and strawberry Daiquiris are later variations.

Why is my Daiquiri too sour?

Fresh lime acidity varies. Check the syrup concentration, then increase 1:1 syrup by 5 ml in the next drink instead of changing several variables.

Can I serve a Daiquiri over ice?

The classic is served up. A large-rock version is workable at home, but it will continue to dilute and should be treated as a variation.

Is a Daiquiri low in alcohol?

No. It contains a full 60 ml pour of rum. Cold temperature and acidity can soften the alcohol impression without lowering the dose.
