Selecting the Right Milk for Steaming
The milk you choose will significantly affect your milk-steaming results. Whole milk is favored for its rich, creamy texture and high-fat content, which aids in creating thick and velvety microfoam. For a lighter texture, skim milk can be used, though the foam will be more airy. See what makes these machines stand out in the Breville Barista Pro vs Express review
For non-dairy alternatives, oat milk (particularly barista-grade varieties) is known for its consistency and creaminess. It’s an excellent choice for those who prefer a plant-based option, as it produces reliable microfoam and a smooth texture.

Use a stainless steel milk jug, as it provides better heat conduction and allows you to feel the milk's temperature by touch. Fill the jug with cold milk, just below the spout, for optimal steaming time before overheating occurs.
Step-by-Step Guide to Steaming Milk on the Breville Barista Express
1. Purge the Steam Wand
Start by purging the steam wand. Turn the steam knob briefly to release any residual condensation, ensuring dry steam for the best foam. This step prevents unwanted watery steam, which can affect the texture of the foam.
2. Position the Steam Wand
Correct positioning of the steam wand is crucial. Place the wand’s tip just below the surface of the milk near the spout, holding the jug at a slight angle. This allows for efficient air incorporation and helps establish a whirlpool motion, which is key to achieving consistent, creamy microfoam.
3. Stretch the Milk (Incorporate Air)
Turn the steam knob to full power and listen for the familiar hissing sound. Hold the steam wand just beneath the surface of the milk for the first few seconds to "stretch" the milk by incorporating air. Be cautious not to overdo it, as too much air will create large bubbles, rather than the smooth, silky foam you desire.
4. Texture the Milk
Once you've added enough air, raise the jug slightly to submerge the steam wand fully. The goal now is to texture the milk, heating it while maintaining the whirlpool motion. This helps break down any large bubbles and transforms the milk into a shiny, velvety foam. The texture should resemble wet paint—smooth and glossy.
5. Monitor the Temperature
Maintaining the right temperature is key to perfect milk. You can feel the jug’s outside—when it becomes too hot to touch comfortably (around 150°F or 65°C), stop steaming. If you’re aiming for precise control, using a thermometer ensures the milk doesn’t overheat. Overheating can cause burnt-tasting milk and spoil the natural sweetness.
6. Turn Off the Steam
Once you've reached the desired temperature, turn off the steam before removing the wand to prevent splattering. Set the jug aside carefully to prepare for the final touches.
Final Touches for a Perfect Cup
Tap and Swirl the Milk
After steaming, gently tap the jug on the counter to break up any large bubbles. Then, give it a swirl to achieve a smooth, glossy finish. Skipping this step can leave you with a less desirable texture, so always take the time to perfect the foam.
Clean the Steam Wand
Clean the steam wand immediately after use. Wipe it down with a damp cloth and purge it once more to remove any milk residue. Regular cleaning ensures the wand remains in optimal condition and prevents buildup that can affect performance.
Pour the Milk
When it’s time to pour, tilt the coffee cup slightly and pour from a higher point to combine the milk and espresso. As you approach the end of the pour, lower the jug to create beautiful latte art if you wish. Mastering latte art takes time, so be patient and keep practicing!

Expert Tips and Tricks for Perfect Steamed Milk
Practice Consistently
Steaming milk takes time and consistent effort to master. Don't get discouraged if it doesn't come out perfectly on your first try. Each attempt is a step toward improvement, so practice and refine your technique.
Use Fresh Milk
For the best microfoam, always use fresh milk. Fresh milk contains the right amount of protein to create a stable foam. Avoid using milk that's close to expiration or has been open for too long.
Experiment with Different Milk Types
While whole milk is ideal for creating rich, creamy foam, plant-based milks can also yield great results. Barista-style oat milk is particularly known for producing quality foam and is an excellent alternative for those avoiding dairy.
Common Mistakes to Avoid
Over-Aerating the Milk
Excessive air leads to frothy, large bubbles instead of smooth microfoam. Focus on a soft hiss and limit the amount of air you incorporate into the milk to avoid this mistake.
Overheating the Milk
Milk burns at temperatures above 170°F (77°C). Always keep an eye on the temperature and stop steaming as soon as the jug becomes too hot to touch. Overheated milk loses its natural sweetness and becomes scorched.
Neglecting to Purge and Clean the Steam Wand
Skipping the purge and clean can lead to clogs and performance issues over time. Always make sure to clean the steam wand immediately after use to maintain its functionality.
Exploring Latte Art
Once you've mastered the basics of steaming milk, you can experiment with latte art. Start with simple shapes, like hearts or rosettas, and gradually progress to more intricate designs. Latte art takes practice, so don’t worry if your first attempts aren’t perfect—perseverance will lead to improvement!
