A cappuccino at home does not need to feel like a small science project. With a good espresso, cold milk and a few minutes of attention, you can make a cup that tastes soft, full and properly café-like. The classic ratio is simple: 25 ml espresso with 100 ml cold milk, frothed to around 125 ml. Below, you will learn how to make it — with or without a steam wand — and what to do when the foam is not cooperating yet.
TL;DR
- The 2006 INEI standard sets a cappuccino at 25 ml espresso and 100 ml cold milk that froths to 125 ml (Istituto Nazionale Espresso Italiano, 2006).
- Start with milk straight from the fridge and stop frothing at 55 to 65 °C.
- No steam wand? A handheld frother, a French press or a jar you shake will work too.
- Plant-based can work too. In a 2022 test, plant-based barista drinks foamed about as well as cow's milk at 65 °C (Zakidou et al., International Journal of Gastronomy and Food Science, 2022).
- Foam gone wrong? The troubleshooting table further down tells you why.
What's the right cappuccino ratio?
A classic cappuccino is 25 ml espresso and 100 ml cold milk, frothed up to 125 ml, in a 150 to 160 ml cup. That's the 2006 INEI standard for a certified cappuccino (Istituto Nazionale Espresso Italiano, 2006). The espresso is about a sixth of the 150 ml in your cup.
The popular 1/3 rule (a third espresso, a third milk, a third foam) matches the layers you see in the cup, not what you pour. By volume, the espresso is only a small part of the drink. When you measure, you measure the cold milk you pour into the jug.
The standard covers the foam too. INEI wants dense, fine foam with very small or no visible bubbles. Separately, the 2006 spec calls for fresh cow's milk with at least 3.2% protein and 3.5% fat (Istituto Nazionale Espresso Italiano, 2006). You don't need a certificate at home, but it gives you a target: smooth foam with no big bubbles.
Cappuccino recipe by cup size
For a 150 ml cup, use 1 shot of espresso and 100 ml cold milk. Got a bigger mug of 200 to 300 ml? Scale both to fit, as the table below shows. The figures are scaled up from the Italian standard of 25 ml espresso to 100 ml milk.
| Cup size | Espresso | Cold milk to start with |
|---|---|---|
| 150 ml | 1 shot (25 ml) | 100 ml |
| 200 ml | 1 shot | 140 ml |
| 250 ml | 2 shots | 160 ml |
| 300 ml | 2 shots | 200 ml |
The milk in the table is cold starting milk. Under the 2006 standard, 100 ml of milk froths up to 125 ml (Istituto Nazionale Espresso Italiano, 2006), so the foamed milk fills the cup. For each row, subtract the espresso from the cup size, divide what's left by 1.25 and round to the nearest 10 ml.
Treat this cappuccino recipe as a starting point, because plenty of home mugs are bigger than the standard's 150 ml. The table works in whole shots, so the ratio drifts a little from row to row. Want more coffee flavour? Go for 2 shots and less milk.
How do you make a cappuccino with a steam wand?
Here's how to steam milk with a wand: add some air first, then spin the milk until it reaches 55 to 65 °C. In 2014, researchers tested milk from 5 to 60 °C and found it foamed worst at 25 °C (Oetjen et al., Colloids and Surfaces A, 2014).
The 2006 INEI standard also gives a milk temperature target: around 55 °C (Istituto Nazionale Espresso Italiano, 2006). A 2023 study found that steaming at 60 to 65 °C did not seem to affect the nutritional quality of milk (Santini et al., Food Chemistry, 2023). Above that, some vitamins declined. So aim for 55 to 65 °C.
- Pull your espresso, or let it run while you froth the milk.
- Pour cold milk from the fridge into a cold stainless steel jug, up to just below the spout.
- Let the wand release a short burst of steam to clear it.
- Hold the tip just under the surface of the milk and let a little air hiss in for a few seconds.
- Lower the tip slightly, so the milk starts to spin.
- Stop when the jug is too hot to hold comfortably. A thermometer is more accurate than your hand.
- Tap the jug on the worktop and swirl the milk, so big bubbles disappear and the foam turns glossy.
- Pour the milk straight into your espresso.
Steaming milk takes practice. Your first jug will probably come out too hot or too coarse. That comes with the territory, and after a few jugs you'll feel when it's getting too hot to hold.
How do you make a cappuccino without a steam wand?
Warm the milk to about 60 °C, then froth it with a handheld frother, French press or whisk. A jar works too, but its steps run in a different order. A 2025 study found in lab experiments that whisking gave more air and coarser bubbles than steam (Wüest et al., Food Hydrocolloids, 2025).
Hand-frothed milk often feels stiffer than foam from a steam wand, so it needs a little finishing. Tap the jug or jar on the worktop, swirl the milk and let it rest for 30 seconds. If the top layer is still too stiff, spoon some of it off before you pour.
Frothing by hand takes a bit more effort than a steam wand, but you probably own most of the kit already. Here's how to froth milk without a frother: pump warm milk 15 to 20 times in a French press, or use a jar.
For the jar, shake cold milk with the lid on, then take the lid off and put the microwave-safe jar in the microwave for a short burst. The microwave does the warming here. Careful, the milk gets hot.
The table below compares the methods without times or foam heights, because those depend on your milk and your hand.
| Method | What you need | Type of foam | Best if |
|---|---|---|---|
| Electric handheld frother | Frother, tall jug and warm milk | Airy and fairly firm | You want a quick cup with no fuss |
| French press | French press and warm milk | Firm, with a thick top layer | You already own a French press |
| Jar with a lid | Microwave-safe jar with a lid, and a microwave | Firm and dry | You have nothing else at home |
| Whisk | Whisk and a pan or bowl | Firm, with coarser bubbles | You're warming the milk in a pan anyway |
To make a cappuccino with a handheld frother or French press, grab a tall jug, because milk expands as you froth it. Don't fill the jug too full, so the foam has room. Then pour the frothed milk over your espresso.
No espresso machine? Here's what to brew instead
No machine? Pick a moka pot, an AeroPress or strong filter coffee in a small volume. None of the three is real espresso. Add frothed milk and you get something closer to a koffie verkeerd (the Dutch milky coffee) with a thick foam cap. Still pretty good.
- Moka pot gets closest to espresso with a strong, compact brew.
- AeroPress makes a short, strong cup with little water.
- Filter coffee works with a double dose and a small volume.
Making cappuccino with filter coffee works, as long as you keep the coffee small and strong. You'll miss the crema, but with milk on top you notice it less. For what really sets espresso apart from regular coffee, read the difference between espresso beans and coffee beans.
Which milk froths best for cappuccino?
Whole milk is standard: INEI's 2006 spec requires at least 3.5% fat and 3.2% protein (Istituto Nazionale Espresso Italiano, 2006). In a 2022 test at 4 °C (cold foam), cow's milk foamed better than plant-based drinks. At 65 °C, all foamed about as well (Zakidou et al., International Journal of Gastronomy and Food Science, 2022).
Protein levels vary widely. In a 2022 test, the two cow's milks had 3.16 and 3.61 g of protein per 100 ml and the soy drink 3.12 g. Coconut-soy had 1.33 g and oat 0.50 g (Zakidou et al., International Journal of Gastronomy and Food Science, 2022). Both cow's milks were UHT.
In that test, soy foamed better than oat and coconut-soy at 4 °C. But the tasting panel rated soy lower on taste and overall acceptance than the other four (Zakidou et al., International Journal of Gastronomy and Food Science, 2022).
For plant-based, try a barista soy and a barista oat and keep the one you like. A 2025 study found that plant-based foam lost liquid faster in lab experiments (Wüest et al., Food Hydrocolloids, 2025). Those were model systems, not cartons from the shop.
The kind of milk counts too. A 2023 study found that pasteurised milk gave more consistent foam that lasted longer than long-life UHT milk (Santini et al., Food Chemistry, 2023). So buy milk from the chilled section if you want foam that sticks around.
A 2010 paper found that skimmed milk makes very stable foam, while fat makes foaming harder, especially at around 20 °C (Huppertz, International Journal of Dairy Technology, 2010). Skimmed milk does taste thinner, though. Whole milk is the INEI standard and gives you more flavour.
Why won't your milk foam?
Usually it's the temperature or the milk itself. A 2014 study found that lukewarm milk, around 25 °C, foams worst (Oetjen et al., Colloids and Surfaces A, 2014). If your milk won't froth, find your problem in the table below and try the fix next to it.
| Problem | Cause | Fix |
|---|---|---|
| Big bubbles | You let air in for too long or didn't tap the jug. | Keep the hissing short, tap the jug on the worktop and swirl the milk until it looks glossy. |
| Foam collapses within a few minutes | You started with lukewarm milk or used long-life UHT milk, which foamed less consistently than pasteurised milk in a 2023 study (Santini et al., Food Chemistry, 2023). | Start with cold milk from the fridge. |
| No volume | In a 2014 study, milk at around 25 °C foamed worst (Oetjen et al., Colloids and Surfaces A, 2014). | Use milk straight from the fridge and keep the tip just under the surface at first. |
| Tastes cooked or bland | You let the milk get too hot, or went for skimmed milk. | Stop at 55 to 65 °C and pick whole milk for more flavour. |
| Plant-based milk goes flat or watery | A 2025 study found that plant-based foam lost liquid faster in model systems (Wüest et al., Food Hydrocolloids, 2025), and not every carton is made for frothing. | Try a barista soy or oat and pour straight after frothing. |
| Milk and foam sit separately in your cup | You didn't swirl the milk, or let the jug stand too long. | Tap the jug and swirl the milk right before pouring. Pour gently into the middle of the cup. |
No thermometer? Your hand is the gauge, though a thermometer is more accurate. If you need a second go, start again with fresh cold milk. Milk you reheat starts out lukewarm, and lukewarm milk foams badly.
Milk first or coffee first?
Pour the espresso into your cup first, then the milk. That way the foam ends up on top and the crema stays with the espresso. Froth the milk right after and pour straight away, so the foam doesn't collapse and the layers of espresso, milk and foam stay neatly visible.
Pour the milk slowly into the middle of the cup, hold the foam back with a spoon and let the last layer slide on top.
Which coffee beans should you use for cappuccino?
Pick a medium to medium-dark roast, because milk makes acidity and subtle flavours less noticeable. That kind of roast holds its own next to milk and foam, while a light roast disappears into it faster. To see how light and dark roast differ, read light vs dark roast coffee.
Robusta, the other big coffee species alongside arabica, tastes more bitter and bolder: arabica vs robusta lays out the difference.

Frequently Asked Questions
How much caffeine is in a cappuccino?
It depends on your shot. EFSA uses 80 mg of caffeine for a 60 ml espresso, and a 25 ml shot is smaller. In 2015, EFSA concluded that healthy adults can safely take up to 400 mg a day, pregnant women up to 200 mg (EFSA, 2015). More numbers: caffeine in coffee.
What's the difference between a cappuccino and a latte?
A latte is bigger and has more milk with a thin layer of foam. A cappuccino is smaller, with less milk and a thick foam cap on top. So a cappuccino tastes more of coffee, while a latte is mostly soft, warm milk.
Can you make cappuccino with filter coffee?
Yes. Brew the coffee at double strength in a small volume and froth warm milk on top. It isn't espresso, so the taste is different and you'll miss the crema. It works fine for a mild cappuccino.
Can you make cappuccino with oat milk?
Yes, it works. In a 2022 test at 4 °C (cold foam), a barista oat drink foamed worse than soy, with 0.50 g of protein per 100 ml against 3.12 g. At 65 °C, all the tested drinks foamed about as well (Zakidou et al., International Journal of Gastronomy and Food Science, 2022). Try a barista version.
How hot should milk be for a cappuccino?
Between 55 and 65 °C, roughly the point where the jug is too hot to hold comfortably. A 2023 study found that above 65 °C some vitamins decline (Santini et al., Food Chemistry, 2023).
How do you make a cappuccino without a milk frother?
Warm the milk to about 60 °C and pump it 15 to 20 times in a French press. Or shake cold milk in a jar with the lid on, take the lid off and put the microwave-safe jar in the microwave for a short burst. Careful, the milk gets hot.
Start with the standard, finish with your own cup
Take the ratio of 25 ml espresso to 100 ml milk as a starting point and scale it up to your own mug. Start cold, stop at 55 to 65 °C and check the troubleshooting table to see what went wrong. It takes practice: your third jug will beat your first.
