How to Steam Milk for a Latte at Home
Good steamed milk is smooth and glossy, with tiny bubbles you can barely see. That texture is called microfoam. It's what makes a latte feel creamy, and it's what latte art is poured with. Here's how to make it.
You'll need
- An espresso machine with a steam wand.
- A metal milk pitcher, about 12 oz for one drink.
- Cold milk. Whole milk is the easiest to learn with. Many oat "barista" milks steam well too.
Step by step
- Fill the pitcher to just below the spout, about a third full. Milk grows as it steams.
- Purge the wand. Open the steam for a second into a cloth or the drip tray to clear water.
- Place the tip just below the surface, slightly off-center, with the pitcher tilted a little.
- Open the steam fully.
- Stretch: add air for a few seconds. Keep the tip near the surface so you hear a gentle tearing or hissing sound. The milk level will rise. For a latte, stretch only a little. For a cappuccino, stretch longer.
- Spin: sink the tip slightly so the milk starts swirling in a whirlpool. This breaks big bubbles into tiny ones.
- Stop when the pitcher is hot to hold, around 140 to 150°F (60 to 65°C). Hotter milk loses sweetness.
- Turn off the steam, then remove the wand. Wipe it straight away with a damp cloth and purge again.
- Tap and swirl. Tap the pitcher on the counter to pop any big bubbles, then swirl until the milk looks like wet paint.
Pour into your espresso right away, before the foam separates.
Fixing common problems
- Big, bubbly foam: the tip was too high or you added air too long. Keep it closer to the surface and stretch for less time.
- Flat milk with no foam: the tip was too deep from the start. Begin right at the surface.
- Screaming noise: the tip is too deep. Lift it slightly.
- Milk is scalded or tastes burnt: you went too hot. Stop as soon as the pitcher is hot to hold.
The easy way
If you'd rather not learn wand technique, some machines steam milk automatically. The Breville Bambino Plus lets you choose temperature and texture, and the Ninja Luxe Café Premier has hands-free froth presets. See our home espresso machine comparison.
