How to steam milk: stretching and texturing with a steam wand
How to steam milk with an espresso machine's steam wand: the jug, cold milk, the stretch and texture stages, the right temperature, and how it changes for a latte, cappuccino or flat white.
Learning how to steam milk on an espresso machine is mostly about two stages. First you stretch the milk, letting a little air in near the surface. Then you texture it, sinking the wand slightly so the milk spins and the bubbles break down into smooth microfoam. Sage’s own recipes sum it up as “texture first, then temperature”, with dairy milk finished at around 60 to 65°C. We haven’t tested this in person. This guide is based on Sage’s barista recipes and machine manuals and De’Longhi’s Dedica manual, all read on 3 Oct 2026. Read how we compare.
How to steam milk: the short answer
- Fill a cold jug with cold milk, up to the bottom of the spout.
- Purge the steam wand to clear water.
- Put the wand tip about 1.5cm into the milk and open the steam.
- Lower the jug slightly for a few seconds so the tip draws in air. That’s stretching.
- Raise the jug a little so the milk swirls. That’s texturing.
- Stop at about 60 to 65°C, or when the jug is too hot to hold.
- Purge and wipe the wand, then swirl and tap the jug before pouring.
Who it isn’t for: owners of machines with an automatic milk system, such as a bean-to-cup carafe. Those do the steaming for you, so follow your manual instead.
What you need
- An espresso machine with a steam wand. Manual wands give you the most control. Some machines have automatic or panarello-style wands, covered below.
- A stainless steel milk jug. Sage’s Barista Express comes with a jug that has a temperature indicator strip. Our guide to the best milk jug for latte art compares sizes and spouts.
- Fresh, cold milk. Sage and De’Longhi both tell you to start with milk straight from the fridge.
- A damp cloth for wiping the wand straight away.
Stretching and texturing, step by step
1. Fill the jug
Sage’s latte and flat white recipes say to pour cold milk up to the bottom of the spout. For a single cappuccino, its recipe says a third of the jug. The milk will grow as you add air, so don’t overfill it.
2. Purge the wand
Open the steam for a moment with the wand pointed over the drip tray. This clears any water sitting in the wand, which would otherwise dilute your milk.
3. Position the tip
Put the tip about ½ inch, or 1.5cm, into the milk, as Sage’s recipes suggest. Sage’s Barista Express manual says 1 to 2cm below the surface, close to the right-hand side of the jug at the 3 o’clock position.
4. Stretch: add air
Open the steam fully. After a few seconds, lower the jug slightly so the tip sits just under the surface. Sage says this introduces air to the surface of the milk. The milk will start to rise as air goes in.
How long you stretch decides how much foam you get. Stretch briefly for a flat white, a bit longer for a latte, and longest for a cappuccino.
5. Texture: spin the milk
Once you’ve added enough air, stop lowering the jug and keep the tip just under the surface while the milk heats. This is where you focus on texture. Sage’s recipes say to aim for a “velvety and silky-smooth texture”, and to get the texture right before worrying about temperature.
6. Stop at the right temperature
Sage aims for about 60 to 65°C for dairy milk. Its Barista Express manual gives the same range. For plant milks, Sage says not to go above about 55°C, because they can separate or curdle.
No thermometer? Sage’s flat white recipe suggests steaming until the jug becomes too hot to touch. On the Barista Express, turn the dial back to standby before you lift the jug out, so you don’t spray milk.
7. Clean up and pour
- Wipe the wand straight away with a damp cloth, then purge it again over the drip tray. Sage’s manuals say this clears milk from inside the wand.
- Swirl the jug and tap it on the counter to knock out any big bubbles and keep the foam mixed in.
- Pour into the espresso. For a latte, Sage suggests starting high and bringing the jug closer as the cup fills.
Who it isn’t for: anyone in a hurry on a single-boiler machine. Sage notes that if your machine has one heating element, you should brew the shot first and then steam the milk.
How steaming changes for each drink
The difference is mostly how much air you add, which sets how deep the foam is:
- Flat white: the least foam. Sage says to aim for a head of about ¼ inch, or 5mm, so it’s flat on top.
- Latte: a bit more. Sage aims for about ½ inch of microfoam, more than a flat white but less than a cappuccino.
- Cappuccino: the most foam of the three. Stretch for longer, and swirl well so the foam is evenly mixed.

Machine notes
Sage Bambino Plus: the automatic wand
The Bambino Plus can steam milk for you. Its manual gives three temperature settings (Warm, Ideal and Hot) and three foam levels (Low, Medium and High). Fill the supplied jug between its MIN and MAX lines, stand it on the temperature sensor on the drip tray, and make sure the milk covers the wand tip. Press steam, and it stops by itself at the set temperature. When you lower the wand, it purges automatically.
Sage says to use only the supplied stainless steel jug on this machine, because other containers can be dangerous. Our Sage Bambino Plus review covers the machine in more depth.
Who it isn’t for: anyone who wants to practise latte art technique by hand. The automatic mode takes over the stretching and texturing.
De’Longhi Dedica EC685: the panarello wand
The Dedica has what De’Longhi calls a cappuccino maker, a panarello-style sleeve on the wand that draws in air for you. Its manual says:
- Use about 100g of milk per cappuccino, at fridge temperature (about 5°C).
- For a denser froth, use skimmed or semi-skimmed milk.
- Choose a jug big enough for the milk to double or triple in volume.
- Set the ring to “CAPPUCCINO” for froth, or “HOT MILK” for hot milk without froth.
- Release a little steam into an empty container first to clear the air.
- Dip the wand in the milk, but never the black ring. For a creamier froth, rotate the jug with slow upward movements.
- Stop at about 60°C, which De’Longhi calls ideal.
- Don’t steam for more than 60 seconds at a time.
Clean the cappuccino maker after every use. De’Longhi says to release a little steam to clear it, let it cool, then take it apart and check the holes aren’t blocked.
Who it isn’t for: anyone after fine latte art microfoam. A panarello makes good froth easily, but gives you less control than a manual wand.
Common problems
- No froth on a Dedica: De’Longhi’s troubleshooting says check the ring is in the “CAPPUCCINO” position, the milk is fridge-cold, and the cappuccino maker is clean. Limescale can also be the cause, so descale if it’s due.
- Milky drink not hot enough on a Barista Express: Sage’s troubleshooting table says to heat the milk until the side of the jug is hot to touch.
- Plant milk splitting: Sage says it can separate or curdle above about 55°C, so stop sooner.
- Bubbly, uneven foam: swirl the jug and tap it on the counter before pouring, as Sage suggests.
FAQ
What temperature should steamed milk be? Sage aims for 60 to 65°C for dairy milk and no more than about 55°C for plant milks. De’Longhi calls 60°C ideal.
What’s the difference between stretching and texturing? Stretching adds air near the surface. Texturing spins the milk to turn that air into smooth microfoam.
Can you steam milk without a steam wand? Not really, but you can froth it. See how to froth milk without a frother.
