Top Tips on How to Froth Milk on Your Espresso Machine

The Essentials of Milk Frothing

Choosing the Right Jug

Always opt for stainless steel jugs when frothing milk. Unlike plastic, glass, or china, stainless steel provides excellent heat transfer, which is crucial for the frothing process.

Milk Selection

• Chilled Fresh Milk: Cold milk incorporates air more easily, making it ideal for frothing.
• Full-Fat vs. Low-Fat Milk: Full-fat milk produces a denser and longer-lasting foam compared to low-fat milk. However, the choice ultimately depends on personal preference.

Jug Capacity

Ensure the jug is no more than half full, as the milk volume will double during frothing.

Step-by-Step Frothing Process

Preparing the Steam Wand

1. Purge the Steam Wand: Remove any water residue by purging the steam wand. Ensure none of the steam jets are blocked.
2. Positioning: Place the steam wand so that the jug can easily pass under the tip.

Frothing Technique

1. Initial Placement: Position the steam wand tip about 1 cm below the milk surface, centered in the jug.
2. Steam Valve: Turn the steam valve fully on.
3. Adjusting Depth: Hold the jug with both hands and adjust the wand tip depth until you hear a "tssss tssss" sound, indicating air is being drawn into the milk.
4. Rising Milk Level: As the milk expands, lower the jug slowly, keeping the tip just below the surface.
5. Fine-Tuning: If the milk bubbles too fiercely, raise the jug slightly. If you hear a screech, lower the jug slightly.

Avoiding Common Mistakes

• Large Bubbles: Avoid breaking the milk surface with the wand tip to prevent large bubbles.
• Swirling: Lower the wand tip towards the jug bottom and move it to one side to create a swirling motion. This adds texture by forming tiny bubbles.

Final Steps

1. Heating: Continue swirling until the jug side is too hot to touch comfortably and the growl becomes a low purr.
2. Turning Off Steam: Turn off the steam quickly while the wand tip is still submerged.
3. Cleaning: Remove and clean the wand.

Finishing Touches

1. Tapping and Swirling: Tap the jug on the counter and swirl it gently to achieve a firm, velvety foam over hot steamed milk.
2. Pouring: Pour the mixture over an espresso by gently rocking the jug to ensure the right combination of hot milk and foam.
