Milk won't foam when steaming
Steamed milk stays flat with little or no foam forming.
Applies to: Espresso machine, Cappuccino, Latte, Flat white
Safety note
The steam wand and the milk jug both get hot enough to burn skin quickly. Keep hands clear of the wand tip while steam is flowing, and use a cloth or handle rather than gripping the jug body directly once it's warm.
Likely causes and adjustments
Try one adjustment at a time so you know what actually changed the result. Start with the first cause below — if it doesn't help, reveal the next.
Cause 1 of 3 · Reported, not independently verified
Milk already too warm when air is introduced
Start with cold milk and introduce air early, before the milk warms significantly.
Learn the technique
Step-by-step guides to the skills this problem comes from.
- Steaming milkProduce hot milk with a fine, integrated foam that pours as one liquid rather than as foam sitting on milk.
- Steaming plant milkTexture a plant milk without splitting it, and know when the carton rather than the technique is the problem.
- Frothing milk without a steam wandGet a usable milk foam using an electric frother, a whisk, a French press or a jar, and know what each can and cannot produce.
- Purging and wiping the steam wandClear milk from the wand before it dries, so the next drink is not made through yesterday's residue.
