How to Froth Milk for a Flat White?

Quick answer

To froth milk for a flat white, steam cold milk with the wand tip just under the surface for only a couple of seconds to add a little air, then lower the jug so the milk spins into silky microfoam, stopping at about 60 to 65 degrees C (140 to 150 F). It should look glossy, not stiff.

How do you froth milk for a flat white?

A flat white uses thin, glossy microfoam, not the stiff foam of a cappuccino. The method has two phases: stretch (add air) and spin (blend it in). Breville’s advice is texture first, then temperature: build the foam before heating further.

Steam wand steps

  1. Start cold. Pour cold whole milk into a cold jug, leaving room for the milk to expand. Whole milk is the usual choice.
  2. Purge the wand. Open the steam for a second before and after use to clear water.
  3. Stretch. Place the tip just below the surface, slightly off center, and let in air for only a couple of seconds. You should hear a gentle tearing or hissing sound.
  4. Spin. Lower the jug slightly so the tip sits deeper. The milk should spin in a whirlpool, breaking bubbles into microfoam.
  5. Stop at temperature. Aim for about 60 to 65 degrees C (140 to 150 F). If the jug is too hot to hold, it is too hot.
  6. Finish. Wipe and purge the wand. Tap the jug on the counter and swirl until glossy like wet paint, then pour.

No steam wand?

  • Heat the milk in a pan until steaming but not boiling, then use a handheld frother just under the surface and lower it to blend the foam.
  • Or pump the warm milk in a French press until it doubles in volume, then tap out large bubbles.

Troubleshooting

Problem Likely cause
Big bubbles Tip too deep or too much air
Thin and watery Not enough air, or water in the wand
Stiff foam Too much air for too long
Burnt taste Overheated milk

Tips

  • Do not re-steam milk you have already steamed.
  • Practice with the same milk brand each time.
  • Use a thermometer until you can judge by touch.
  • Check your machine manual, since steam power varies.
