What kind of milk is recommended for foaming?
Fresh milk 3% fat in all espresso-based drinks. We use this kind of milk because it gives cappuccino and café au lait extra thickness and a better foam. The milk serves to prepare espresso-based beverages in two forms, foam and steamed milk.
Note: Never forget to release the steam before inserting the tip of the wand into the foaming or heating jug. This releases the condensed water from the faucet, which is liable to spoil the milk.
