2. Frothing Milk

The 10mm powerful steam wand creates creamy, silky smooth micro-foam milk. The dual boiler system allows for simultaneous brewing and steaming without delay.

1. Add cold whole milk to the milk pitcher (approx. 1/3 full).
2. Wait for the 'Steam/Cool' light to stay on, indicating the steam wand is ready.
3. Release some hot water from the steam wand until steam starts to flow consistently.
4. Submerge the steam wand tip just below the milk surface and press the 'Steam/Cool' button to start frothing.
5. Froth until desired texture and temperature are achieved (approx. 140-150°F).
