In this post, we’ll tell you the basic steps and theory behind steaming milk with your espresso machine. You’ll get the right texture and temperature and get on your way to being a latte art master.

When you steam milk, you use steam from your espresso machine to push air into your milk–ideally creating a silky texture we refer to as microfoam–while also heating your milk. This textured milk creates a more-pleasant feeling drink and is necessary for pouring latte art.

How do you create microfoam in your milk?

Steaming milk can be intimidating. If you’ve never done it before, there’s no reason any of its motions should feel natural. But if you follow these steps on focus on using your senses (listening to the sound your milk is making, feeling your pitcher for temperature), you’ll get the hang of it in no time.

Your step by step guide

• Fill your pitcher just a little less milk than you’ll need to fill your cup. The milk should be cold.

• Insert your steam wand into your pitcher until the tip is just underneath the surface

• Turn the steam wand on all the way.

• Slightly lower the pitcher until you hear a steady “chk-chk-chk” sound and/or see the milk starting to increase in volume.

• When the pitcher feels warm to the touch, raise your pitcher, burying the steam wand and stopping that “chk-chk-chk” sound. Keep steaming and using the steam of the wand to spin the milk until it’s as hot as you’d like it.

• Turn off the steam wand. As the experts at La Marzocco point out, your milk should be as glossy as wet paint. If there are any bubbles on the surface, firmly knock your pitcher against the edge of your counter.

• Wipe your steam wand thoroughly with a damp rag.

How do you use that milk to pour basic latte art?

There are many different size drinks and you might want to put slightly more or less foam for different drinks (though in many modern specialty shops, the age of the foamy cappuccino has long passed). But, generally, you’ll be steaming and pouring milk pretty similarly no matter your drink. 

Pouring that milk into latte art won’t necessarily make your drink tastier, but presentation counts even when making drinks for yourself, and once you get the basics down, it can be really fun. 

• Take the cup with your espresso in one hand and your pitcher in another, and tilt the cup towards the pitcher.

• Slowly pour from a few inches above the cup into the center of your espresso.

• When the liquid in your cup starts to approach the rim of the cup closest to your pitcher, you’re going to do a few separate, but related things.

• Bring your pitcher down towards the surface of the liquid. Then start pouring faster, while also straightening the cup, aiming for the same spot in the center the whole time.

• If you’ve steamed your milk correctly, you should start seeing a white dot forming and increasing in size. If you keep filling it, you’ll get the most basic latte art shape: a slightly indented dot we call a Monk’s Head. If at the very end of your pour, you pull across the cup towards the hand holding the cup, you’ll get a heart. Once you’ve mastered these pours, you are well on your way to becoming a latte art champ.

How do you transform this basic shape to more complex patterns?

If you’ve seen latte art at your favorite specialty coffee shop, you know that hearts are just the beginning. But the principles of “start by pouring in the center until some white appears” and “finish by pulling across” are applicable across many other shapes. Here are some shapes to move onto after you’ve mastered the heart:

• The Tulip is basically poured like a bunch of hearts stacked on top of one another. When you see that first white bubble pop up, instead of continuing to pour in the center, you should stop. Then pour again just above your white bubble, but push towards the back of the cup. Stop again and repeat that process until you have several layers stacked on top of one another, finishing with a final heart at the top.

• The Rosetta creates a fern-like shape by pouring continuously while wiggling, instead of stopping and starting. Instead of pouring steadily in the center, wiggle your pitcher from side to side, first pushing towards your other hand, and then pulling the pitcher back while wiggling the whole time, stopping at the end to create a heart on top. 

The techniques you’ll learn from the Heart, Tulip, and Rosetta can be combined in infinite ways. We’ve already discussed how the heart turns into a tulip, but you can also use the wiggling from a rosetta to create more textured hearts or tulip layers. Or you can pour the first few layers of a tulip, but then finish with a rosetta-like wiggle instead of the top few tulip layers. 

The advent of social media has made improving at latte art much easier. A quick YouTube search shows thousands of latte art videos, and watching people pour is super effective way to improve.
