If you like your coffee with milk foam, such as latte or cappuccino, the next step is to use the steam wand to froth the milk. First, insert the steam wand into the container of cold milk and open the steam valve. Make sure the end of the steam wand is below the surface of the milk, which creates tiny bubbles and makes the milk foam more delicate. Slowly tilt the container and control the amount of steam until the milk expands and forms thick milk foam.

After the milk froth is finished, turn off the steam wand and wipe it clean with a damp cloth. Then, pour the prepared milk froth into the extracted espresso and stir gently to form a delicious latte or cappuccino. Throughout the process, mastering the pressure, temperature and steam volume of the coffee machine is the key. After gradually becoming familiar with these operations, you can easily make high-quality coffee drinks.

Common problems and solutions for steam coffee machines

When using a steam coffee machine, you often encounter some problems that affect the quality and taste of the coffee.
