How to Steam Milk on the Breville

Steaming milk at home might seem daunting at first, but once you get the hang of it, it can become one of the most enjoyable parts of your coffee-making routine. Whether you're crafting a smooth latte, a frothy cappuccino, or a rich macchiato, mastering the technique of steaming milk is essential. The Breville Barista Express is a fantastic machine that makes steaming milk easy and accessible, allowing you to achieve café-quality results at home. In this guide, I’ll walk you through the step-by-step process of steaming milk on the Breville Barista Express, based on my own experiences.

Why Steamed Milk Matters

Steamed milk is an integral part of many espresso-based drinks, adding a velvety texture and creamy flavor that complements the espresso. When you steam milk, you’re doing two key things: creating foam (microfoam) and heating the milk. Properly steamed milk with tiny, uniform bubbles creates a smooth texture that enhances the flavor of the coffee, resulting in a perfectly balanced drink.

Getting Started with the Breville Barista Express

The Breville Barista Express, or Sage Barista Express in the UK, is designed to help you create high-quality steamed milk with its built-in steam wand. This user-friendly steam wand offers enough control to adjust the milk texture based on your preferences, making it perfect for those just learning to steam milk at home.

Essential Equipment

To steam milk on the Breville Barista Express, you’ll need:

  • The Breville Barista Express machine with its steam wand.
  • Cold milk (whole milk is ideal, but plant-based options like oat or almond milk can also work).
  • A stainless steel milk jug for steaming.
  • A thermometer (optional) to monitor milk temperature.

Step 1: Preparing Your Breville for Steaming

Before steaming milk, ensure your machine is properly heated. The Barista Express will signal when it’s ready by illuminating the steam function. I recommend waiting a couple of minutes after turning on the machine to ensure it's fully heated.

Purge the steam wand before you begin to remove any condensation. Simply turn the steam knob for a second to let out any trapped water. This ensures that only steam will enter the milk when you start steaming.

Step 2: Preparing the Milk

Fill your milk jug about one-third full with cold milk. Cold milk from the fridge is ideal, as it gives you more time to create microfoam before the milk overheats. For the best results, I recommend using whole milk due to its higher fat content, which creates a rich, creamy texture. If you're using plant-based milk, look for barista versions designed for steaming, as they froth more easily.

Step 3: Positioning the Steam Wand

The positioning of the steam wand and jug is crucial for achieving the right milk texture. Insert the steam wand just below the surface of the milk, angling it at about 15 to 20 degrees. The tip should be close to the milk’s surface to allow air to be drawn in and create foam.

Tilt the jug slightly to create a vortex, or swirling motion, in the milk. This helps break down large bubbles and ensures the microfoam is smooth and even. The steam wand should remain near the edge of the jug for the best results.

Step 4: Steaming the Milk

Now it’s time to steam. Turn the steam knob to start the steam flow. Initially, you’ll hear a hissing sound as air is incorporated into the milk. For the first 5-10 seconds, keep the steam wand just below the surface of the milk to introduce air and create foam.

After this initial phase, raise the jug slightly to submerge the steam wand deeper into the milk. This allows the steam to heat the milk and refine the microfoam. Aim for a smooth, circular motion in the milk to ensure even texture. This process usually takes around 20-30 seconds.

If you’re using a thermometer, heat the milk to around 150°F (65°C). If you don’t have a thermometer, you can gauge it by touch: when the jug becomes too hot to comfortably hold, your milk is likely at the right temperature.

Step 5: Finishing Up

Once your milk reaches the desired temperature and texture, turn off the steam. Immediately wipe down the steam wand with a damp cloth to remove any milk residue. Be sure to purge the wand again briefly to clear out any remaining milk inside.

Tap the milk jug on the counter to eliminate any large bubbles and swirl the milk gently to integrate the foam. If done correctly, your milk will have a glossy, velvety texture, indicating that your microfoam is just right.

Step 6: Pouring the Milk

Pour the steamed milk into your espresso. Start pouring slowly with the jug close to the cup, then raise the jug slightly as you pour faster to help the foam settle on top. With practice, you can even try your hand at latte art!

Troubleshooting Common Issues

Here are a few common issues and tips for fixing them:

  • Milk doesn’t froth properly: Ensure the steam wand is just below the surface of the milk to draw in air. If using plant-based milk, opt for barista versions designed for frothing.
  • Large bubbles in the foam: Large bubbles are often caused by introducing too much air too quickly. Keep the steam wand tip just below the surface to create a steady stream of small bubbles.
  • Milk overheats: Use a thermometer or touch to monitor the temperature, aiming for around 150°F (65°C). Overheating can cause the milk to scorch and affect the flavor.

Final Thoughts

Steaming milk on the Breville Barista Express is an art that, with practice, can elevate your home coffee experience to café-level quality. By focusing on creating smooth microfoam and heating the milk properly, you’ll be able to craft delicious, velvety drinks like a pro. With time and practice, you'll find yourself enjoying the process and even experimenting with new drinks and techniques!
