How to froth milk like a “barista”

• If possible, use cold and fresh milk with a fat content of approx. 1.5 % or 3 %. Even homogenized milk is suitable – if you prefer.
• Use a frothing container (made of metal) with a minimum volume of 0.5 liters. The size of the container should not be too wide. A small and narrow container is perfect.
• Open the steam valve for approx. 5 seconds to release the condensation water and to create the 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 handle. The steam pervades the milk.
• Keep the frothing container still.
• After a few seconds, you will notice a slight suction in the milk jug. Proper frothing begins. Move the frothing container downwards while 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 is reached, immerse the entire steam nozzle in the frothing container for a short time and close the steam handle.

| Milk proteins “froth” with a temperature up to 77°C. Once this temperature is exceeded, the milk does not froth any further.
---|---

• If there is some milk left in the milk jug, let it cool down; it can be re-used later.
• Advice: When milk frothing is finished, just shake the frothing container a little bit in order to make the milk bubbles ascend to the surface and to get a compact milk froth.
• After frothing the milk, release steam into the drip tray to avoid blockage of the steam nozzle.

RECOMMENDED ACCESSORIES

• Blind filter for brew group cleaning (included with delivery)
• Detergent for brew group cleaning with blind filter (available at your specialized dealer, item no. PAV9001034 or 89450).
• Descaler powder for regular prophylactic descaling of the machine (available at your specialized dealer, item no. PAV9001040)
