Crafting the perfect cup of coffee at home is a rewarding experience. For many, learning to steam milk is one of the more challenging—but ultimately satisfying—skills to master. If you’ve struggled with frothy bubbles or overheated milk, don’t worry. With some guidance and practice, you’ll soon be creating silky microfoam that transforms your homemade lattes and cappuccinos into café-quality delights. This guide will walk you through how to steam milk like a pro using the Breville Barista Express.
Understanding the Breville Barista Express Steam Wand
The Breville Barista Express is well-loved for its versatility and reliability, and the steam wand is a standout feature. Its 360-degree swivel design allows you to position the wand easily, whether you're a beginner or an experienced barista.
Before you begin, ensure the machine is fully warmed up. Wait for the indicator lights to signal readiness—this ensures consistent steam pressure. Skipping this step can result in lackluster foam, as I learned during my early attempts.
Prepping the Milk
Choosing the Right Milk
- Whole Milk: Ideal for beginners because its higher fat content helps create a rich, creamy microfoam.
- Skim Milk: Produces a lighter, airy foam but may lack creaminess.
- Plant-Based Milk: Options like oat, almond, or soy milk can also work well. Barista-grade versions of oat milk, such as Oatly Barista Edition, are particularly popular for creating stable foam.
The Milk Jug
Use a stainless steel milk jug, like the Frothing Pitcher by Rattleware. Stainless steel conducts heat, allowing you to feel the temperature as you steam. Fill the jug with cold milk to about one-third full, just below the spout, giving you room to stretch and texture the milk.
Step-by-Step Guide to Steaming Milk
1. Purge the Steam Wand
Before steaming, turn the steam knob to release a short burst of steam, purging condensation and ensuring dry steam. This prevents watery milk and enhances texture.
2. Position the Steam Wand
Submerge the wand’s tip just below the milk’s surface near the edge of the jug. Tilt the jug at a slight angle to encourage a whirlpool motion. Position
matters greatly, as it helps incorporate air evenly and create the desired texture.
3. Stretch the Milk (Incorporate Air)
Turn the steam knob to full power. You should hear a gentle "hissing" sound, indicating that air is being introduced into the milk. Keep the tip of the wand just below the surface for the first 3–5 seconds to create microfoam. Avoid introducing air for too long, as this will lead to large, frothy bubbles instead of silky foam.
4. Texture the Milk
After stretching the milk, fully submerge the steam wand to focus on heating and integrating the milk. The whirlpool motion is essential here, as it helps eliminate any remaining bubbles and creates a smooth, creamy consistency. The milk should begin to take on a shiny, glossy appearance.
5. Monitor the Temperature
Use your hand to gauge the temperature by feeling the outside of the jug. When it becomes too hot to hold for more than a second (around 150°F or 65°C), stop steaming. Alternatively, use a thermometer like the Frothing Thermometer by X-Chef for precise results.
6. Shut Off the Steam
Turn off the steam knob before removing the wand from the milk. This prevents splattering and ensures a smooth finish.
Finishing Touches
Tap and Swirl
After steaming, tap the jug gently on the counter to pop any remaining large bubbles. Swirl the milk in the jug to blend the foam and liquid, creating a uniform, velvety texture.
Clean the Steam Wand
Wipe the wand immediately with a damp cloth and purge it again to clear any residual milk. Regular cleaning prevents clogs and maintains hygiene.
Pour the Milk
Pour the milk into your espresso at a steady pace. Start from a higher height to mix the milk with the coffee, then move closer to the cup for latte art. If you’re new to latte art, start with a simple heart or dot to practice your technique.
Troubleshooting and Tips
Common Issues
- Bubbly Foam: Indicates too much air was introduced. Ensure the steam wand’s tip is just below the surface and lower it after the initial stretch.
- Flat Milk: Results from not introducing enough air. Keep the wand closer to the surface during the stretching phase.
- Scorched Milk: Happens when the milk is overheated. Stop steaming as soon as the jug is too hot to hold comfortably.
Tips for Success
- Use Fresh Milk: Fresher milk contains more active proteins, which help stabilize the foam.
- Experiment with Plant-Based Milks: Barista-grade versions of oat or almond milk work well for frothing. Pacific Foods Barista Series Oat Milk is a favorite among non-dairy enthusiasts.
- Practice Regularly: Steaming milk is a skill that improves with repetition. Dedicate time to practicing and experimenting with different techniques.
Exploring Latte Art
Once you've mastered steaming, try your hand at latte art. Start with simple designs, such as:
- Hearts
- Rosettas
- Tulips
The secret to good latte art lies in the milk's texture. Well-textured microfoam is smooth and glossy, making it easier to pour intricate designs.
Conclusion
Steaming milk on the Breville Barista Express can elevate your coffee-making experience, transforming simple espresso into indulgent lattes and cappuccinos. With a bit of patience and practice, you’ll be able to create café-quality microfoam right in your kitchen.

A: Glossy milk indicates well-textured microfoam. Ensure you’re creating a whirlpool motion during texturing and not over-aerating during the stretching phase.
Q: What’s the best jug size for steaming milk?
A: A 12–20 oz stainless steel jug is ideal for beginners. It’s easy to handle and offers enough space for proper milk expansion.
Q: Why does my milk taste burnt?
A: Burnt milk results from overheating. Stop steaming when the jug becomes too hot to touch or use a thermometer to monitor temperature precisely.
Q: How do I clean the steam wand properly?
A: Wipe the wand with a damp cloth after steaming and purge it to clear any milk residue. Regular cleaning prevents clogs and maintains steam quality.
