Detailed explanation of the steps of milking in Italian Coffee

Steps

There are three things to do when making milk foam: heating the milk, beating the milk foam and beating the milk foam.

Add milk to the milk pot

Milk should be added to 1 beat, 3 to 1, 2 full.

Start the steam valve to release the water from the steam rod

Insert the steam nozzle into the surface of fresh milk about 3-5MM deep (depending on the steam nozzle and steam intensity will vary slightly)

Open steam valve

A slight hiss should be heard at this time, and the position and angle of the milk kettle should be controlled to form a whirlpool of fresh milk.

(if you insert it too deep, you will hear a roar, but if you don't insert it deep enough, you will see a lot of bubbles and even the milk will jump out.)

Narrow the whirlpool near the ideal temperature (in case of an accident, you'll know if you try)

Close the steam valve

Good milk bubbles must be thick, dense and fine. Milk bubbles should be fused with hot milk, and the surface of milk bubbles should reflect light. Observe the "hanging cup" of this milk pot after each flower. There should be no big milk bubbles. The less small bubbles, the better.

Tips

If you use it for your own use, 140150 ℉ of milk foam will be fine. Don't sell it for more than 180 ℉.

If you use a thermometer, pay attention to the reaction time of the thermometer. It is possible that you turn off the steam valve at 150 ℉ and eventually rise to 180 ℉. Without a thermometer, 120 ℉ is about the time when you start to feel hot.

Do not foam more than 120℉.

The amount of milk foam is about 30-50%.

The steam rod is close to the edge of the pot to make it easier for the vortex to form.

The tilting milk pot can increase the surface area of fresh milk, thus increasing the whirlpool.

Don't rush to pull the milk pot down after hearing the hiss, it will form too many coarse milk bubbles.

There is a piece of black soft glue (like milk frother) on the steam paddle of some machines. If so, you can remove that piece of soft glue.

Use frozen milk

Using whole milk will be easier to master.

Don't shave the foam.

To find the proper depth of the nozzle, you can take a look at the following video. The first four seconds is the appropriate depth, then a few seconds too high, then a few seconds too low, pay attention to the difference between sound and blistering
