Iced Espresso: Recipe, Ice Ratio and Caffeine
Iced espresso is espresso served over ice, usually without added water or milk. It is a smaller, more concentrated drink than an iced Americano made from the same shot. This home recipe uses 18 g coffee to make 36 g espresso, then serves it over 90 g (3.2 oz) ice.

Key Takeaways
- 1Keep two measurements separate: 18 g coffee to 36 g espresso is a 1:2 extraction ratio; the 90 g (3.2 oz) ice is for serving.
- 2The unsweetened serving is estimated at 3 kcal and 75 mg caffeine, using the generic USDA reference for 36 g espresso.
- 3Ice melt changes dilution, not the caffeine already in the shot. Add measured water if you want an iced Americano.

What Makes Iced Espresso Different
Weigh the 36 g brewed espresso output; crema makes volume less consistent. The SCA’s survey of espresso practice reports varied recipes and an average 1:2 ratio.
How to Make Iced Espresso
The three-minute timing assumes the machine is warmed and ready. Start with a coffee you enjoy as espresso; a small iced drink leaves the coffee prominent.
Recipe
Iced espresso
- Makes:
- 1 serving (36 g espresso over 90 g (3.2 oz) ice)
- Time:
- About 3 minutes with equipment ready
Ingredients
- 18 g coffee, ground for espresso, to produce 36 g brewed espresso
- 90 g (3.2 oz) large ice cubes
Equipment
- Espresso machine and grinder
- scale
- heatproof brewing cup
- 160–180 ml (5.4–6.1 US fl oz) rocks glass
Method
- Prepare. Chill a 160–180 ml (5.4–6.1 US fl oz) rocks glass and add 90 g (3.2 oz) large ice cubes. Ready the warmed espresso machine and grinder.
- Brew. Start with 18 g coffee and extract 36 g espresso into a heatproof cup. Adjust the grind for your beans and machine.
- Combine. Pour the fresh espresso over the measured ice and swirl once to mix and chill.
- Serve. Drink promptly. The ice will continue to melt.
Estimated nutrition per serving: 3 calories; total sugar 0 g.
Recipe notes
18 g dry coffee to 36 g espresso is the extraction ratio. Measure the serving ice separately.
Estimated nutrition: 3 kcal and 0 g sugar from the plain espresso.
Optional sweetness: 5 g (0.18 oz) syrup made from equal masses sugar and water adds about 10 kcal and 2.5 g sugar.
For dose, yield and grind setup, use the espresso brewing method.
Pulling into a separate cup lets you weigh the espresso before it meets ice. For capsules, follow the machine’s espresso setting and the capsule’s serving information. Nespresso’s over-ice service illustrates a different 40 ml (1.4 US fl oz) espresso recipe with an optional water extension.
Iced Espresso Compared with Other Cold Drinks
For a sweet almond variation from Salento, see caffè leccese. Its concentrated almond syrup is a different ingredient from a carton of ready-to-drink almond milk.

| Drink | Coffee base | What is added or changed | Choose it when you want |
|---|---|---|---|
| Iced espresso | Espresso | Serving ice | A small black coffee without added water |
| Iced Americano | Espresso | Cold water and ice | A longer black drink |
| Iced long black | Espresso | Espresso added to iced water | A water-first build; size varies by café |
| Iced coffee | Often brewed filter coffee | Chilling and serving ice | A full glass of cold brewed coffee |
| Shakerato | Espresso | Shaken with ice, often sweetened, then strained | An aerated drink served without the mixing ice |
| Freddo espresso | Espresso | Aerated, then served over fresh ice | A cold espresso with a foamy top |
With the same espresso portion, added water changes concentration, not total caffeine. Compare a café’s actual recipe before comparing caffeine.
How to Fix Weak, Harsh or Watery Iced Espresso
Swipe to see all columnsScroll to see all columns
| Problem | What to check | First adjustment |
|---|---|---|
| Weak from the first sip | Unplanned water, a long shot, or espresso that already tastes thin | Verify the 36 g output and taste a separately prepared hot shot |
| Becomes watery while sitting | Meltwater from the ice and time in a warm glass | Chill the glass, use fresh hard ice and serve promptly |
| Sharp and thin, with fast flow | Extraction may be insufficient for this coffee | Try a slightly finer grind at the same dose and yield |
| Bitter and drying, with slow flow | Very fine grind or uneven extraction | Try a slightly coarser grind and check puck preparation |
| Sugar settles at the bottom | Crystals were added after chilling | Dissolve sugar or syrup in the hot espresso first |
I enjoy this while it still has that initial intensity. If I want to linger over a longer coffee, I plan the water and ice accordingly instead of expecting a little espresso to stay unchanged as the cubes melt.
Glass temperature, ice temperature and time all affect dilution. Keep the 90 g (3.2 oz) ice portion consistent when comparing adjustments.
What Melting Ice Actually Changes
Here is our simple mass comparison, assuming all 36 g espresso reaches the glass and ordinary water ice is used:

| Ice melted into the espresso | Liquid coffee plus meltwater | Original espresso portion |
|---|---|---|
| 0 g | 36 g | 36 g |
| 15 g | 51 g | 36 g |
| 30 g | 66 g | 36 g |
These calculated melt amounts show how the liquid becomes more dilute while the original coffee, calories and caffeine remain in the glass.
Iced Espresso Caffeine and Calories
The unsweetened recipe is estimated at 3 kcal, 0 g total sugar and 75 mg caffeine for 36 g espresso over ice. The caffeine estimate uses generic espresso composition; beans and extraction affect the actual amount.

| Defined serving | Estimated calories | Estimated total sugar | Caffeine context |
|---|---|---|---|
| 36 g espresso over 90 g (3.2 oz) ordinary ice | 3 kcal | 0 g | 75 mg generic reference |
| Same drink plus 5 g (0.18 oz) 1:1 syrup by weight | 13 kcal | 2.5 g | Same espresso reference |
Ingredient calculations and sources
The unrounded caffeine calculation is 212 × 36 ÷ 100 = 76.32 mg, rounded to 75 mg. The reference is for the complete 36 g espresso portion, not each spout of a double basket.
For the syrup option, equal masses sugar and water mean that 5 g syrup contains 2.5 g sugar. At approximately 4 kcal per gram of carbohydrate, that adds about 10 kcal. Milk, cream and commercial syrups need their own amounts and label values; decaf also needs a different caffeine reference.
USDA generic espresso provides 9 kcal, 0 g sugar and 212 mg caffeine per 100 g.
Questions About Iced Espresso
Should Espresso Cool Before It Goes Over Ice?
You can pour the fresh shot straight onto measured ice; no waiting period is required for this recipe. If you prefer to cool it first, that changes how much ice initially melts. Keep that choice consistent when comparing adjustments.
Is Iced Espresso the Same as Iced Coffee?
Iced espresso specifically starts with pressure-brewed espresso. “Iced coffee” is broader and often means chilled filter coffee. Japanese iced coffee is hot filter coffee brewed directly onto recipe ice.
Can I Add Water or Milk?
Yes. Water makes a longer drink in the iced Americano family; a substantial milk portion moves toward an iced latte. Measure either addition so you can repeat the result.
Does Crema Prove the Shot Is Good?
No. Foam height is not a reliable score for flavor, and crema changes as the shot meets ice. Use taste alongside dose, yield and flow rather than expecting a permanent thick crema cap on the finished cold drink.
