When learning to pull flowers in coffee, I always can't grasp how to hit the foam, or how to judge the thickness of the foam.

Either the amount of foam is not enough, the foam is too thin, as soon as the shape has not come out, the foam will float away.

Or the foam is too fierce, the milk foam is too thick, a pour is a lump …...

(if the foam is too thick, the one in the middle will not move when shaking the milk tank.)

In fact, it's good to hit thick, and you can save it by dividing the cylinder, but it seems that there is really nothing you can do about it if it is thinned.

Before we talk about how to foam coffee, let's take a look at what we should pay attention to.

| | milk |

Will the difference of milk affect the foam?

In fact, as long as there is protein, because protein is the cause of milk foaming. As for the amount of fat, it will only have a greater impact on the milk coffee. It is recommended to use whole milk with a fat content of 3.2-3.8%. We use Weiji fresh milk, because fresh milk is better in terms of foam density, sweetness and durability.

And it is recommended to use frozen milk, because for most beginners, they are not proficient in the process of foaming, so it takes a long time to beat and beat the foam (which will be explained below). Frozen milk at about 5 °C has the longest heating time and has enough time for beginners to adjust the angle and control the whirlpool.

Do not pour out the remaining milk in the milk tank every time, you can continue to use it after being refrigerated in the freezer, but it should be noted that the temperature must be fully cooled down first. secondly, do not all use the second use of milk for coffee flower, because the milk will contain a lot of water, milk flavor will fade, so at least more than half of the fresh milk should be mixed.

| | Milk tank |

At first glance, the milk jar is just a container for milk. What influence can it have? In fact, the size of the capacity of the milk tank actually has an impact on milk foam! For beginners, it is not recommended to use a too small milk tank, because the capacity of the small milk tank is generally in 300ml, and the amount of milk is generally half of the capacity of the milk tank. At this time, the small milk tank is a test for beginners. Very often, due to overheating, the milk boils out, steam is too fierce, and the whirlpool is not suitable for splashing all over the floor.

| | steam |

Dry steam is important for making a dense and delicate milk foam.

What does dry steam look like? If it is moist steam, you can find obvious water with a cup, and the sound of the steam will have a lot of "puff" hot water sound, or spattered hot water droplets mixed in the steam. On the contrary, dry steam, take the cup to pick up, there will be no water left at the bottom.

Dry steam sticks will heat faster than wet ones, and milk will not be diluted.

Before we talked about some objective conditions, now let's get to the point, how to play milk foam!

| | position, angle and depth |

How to find the position and angle of the steam rod, I believe it is also a difficult task for most novices.

Generally speaking, the angle of the steam stick is about 2-3 o'clock or 9-10:00 of the cylinder on the premise that the nozzle is in the direction of 12:00. This is because we use steam to make the milk rotate as soon as possible and form a small whirlpool, so that the thicker foam can be involved in the milk, making the milk in a dense state.

For beginners who are not familiar with steam rods, they often adjust the vertical angle of steam rods. In fact, normally, there are only two angles that are not desirable (for beginners): 1, completely vertical; 2, maximum angle.

The steam stick is so vertical that most of the steam is ejected downward, making it difficult for the milk to form a small whirlpool: if the steam rod is too flat, most of the steam will be ejected in a parallel direction, making the small whirlpool too large to form turbulence that is difficult to control or milk spill.

Besides, as long as it is fixed and practiced (drawing water), it will be easy to master.

This is not to say that these two angles cannot be foamed, but these two angles are not friendly to beginners: completely vertical, it is difficult to control the whirlpool; when the maximum angle is reached, some coffee machine models will have exhaust failure and obstruction.

It's not all right after you find the location. The steam stick can not reach too deep, because the main purpose of milk is to pump air into the milk. if the steam stick is too deep, how can it come into contact with the air? of course, it is not good to be too shallow, because if it is too shallow, then the milk may splash when you turn on the steam, or the steam foams too much.

Based on about 1cm extending into the coffee machine, if the coffee machine steam is too strong, the vortex is too large or turbulence, then you can put the steam stick into a deeper position (such as 1.5cm); if the coffee machine steam is not strong enough, you can put the steam stick in a shallow position (such as 0.5cm or shallower). So that the milk can form a small whirlpool as soon as possible without spinning too violently or causing turbulence.

| | Milk foam |

Find the right position, angle and depth, then we can turn on the switch and hit a jar of delicate milk foam! In fact, playing milk foam is to do three things:

1, heat the milk; 2, let the air into the milk; 3, let the milk foam in the vat fully blend with the milk.

There are many commonly used ways of foaming milk, but they are roughly divided into two categories:

1. To send off while making love is to combine the stage of getting rid of milk and soaking with milk.

2. The stages of dispelling and beating are separated, that is, the milk is sent first and then the milk is foamed.

Send off

To get rid of it is to put in steam to make the volume of milk foaming.

When we pass the milk, we can hear the sound of "zi zi". If we don't hear it, it may be because the steam stick is too deep, so we can pull the milk tank down a little bit. If there is no sound of killing pigs or no sound, it means that it is not in the process of killing.

When the expansion is eight minutes full, move the steam pipe obliquely to the center of the steel cup to the right near the edge of the steel cup, so that the milk bubble rolls in a whirlpool way.

To get laid.

Splashing is to draw the foamed milk into the air in a whirlpool way, break the larger foam, decompose it into fine foam, and bond the milk molecules to make the foam tissue more compact.

By adjusting the angle between the steam stick and the milk (not the contact point), the milk forms a [whirlpool] in the milk tank, and through the [whirlpool], the foam produced in the process is pulled and torn, and the coarse bubbles decompose into fine bubbles, and the upper foam merges with the lower milk.

During the spanking process, it is not impossible to get rid of air, but you just need to observe and pay attention to the amount of foam and stop the process at the right time. Until the amount of milk foam is sufficient, the coarse foam is completely decomposed, the milk temperature is suitable (60 MFMI 65 °C), and the milk foam is mixed with hot milk, stop beating, turn off the steam and pull out the steam stick.

After being proficient, you can get rid of it first and then have sex, but it is best for a novice to have sex at the same time. In a word, make the milk tumble vertically and bring into the air while rotating horizontally, creating a whirlpool.

PS:

Remember! After milking, you must form a habit, that is, remember to wipe the outside of the steam pipe with a wet cloth! Remember to turn on the steam twice after wiping to facilitate the discharge of milk and other liquids left in the steam pipe.

This is because of the composition characteristics of the milk, so if the steam pipe of the milk is not cleaned in time and regularly, it will be easy to scale. Light makes people look very unhygienic and may cause milk to deteriorate easily; seriously, it clogs the air outlet and reduces the amount of steam. Therefore, it is necessary for us to develop good cleaning and maintenance habits.

Milking is a simple thing that may seem simple, but it's not as difficult as you think! In fact, as long as more practice, pay attention to details, find the feeling will soon be able to get started! In this way, you can start the coffee flower drawing very well!
