How to froth milk like a “barista”
If possible, use cold milk, so you have longer time to froth the milk. The fat content of the milk is not
relevant, the protein content is important. Even homogenized milk is suitable - if you prefer.
Use a metal frothing container with a minimum volume of 350 ml. The container should not be too
wide. A narrow, high container is recommended.
Open the steam valve for approx. 5 seconds to release the water condensation and to create dry
steam.
Fill 1/3 of the frothing container with milk and place it under the steam nozzle. The nozzle should be
immersed in the middle of the frothing container, just below the surface.
Slowly open the steam valve, steaming the milk.
Keep the frothing container still.
After a few seconds you will notice a light suction in the milk jug as frothing begins. Move the milk jug
downwards as the milk level increases. The steam nozzle must be kept under the surface of the
frothed milk.
Attention: When the desired amount of milk froth has been reached, immerse the entire steam nozzle
in the frothing container for a short time and close the steam valve.
Milk proteins “froth” at temperatures up to 77°C.
Once this temperature is exceeded, the milk will not froth any further.
If there is any milk left, you can foam up the remaining milk in the jug again afterwards.
