How does coffee pull flowers?

First, the principle of coffee pulling flowers
The espresso process produces grease (Crema), which is low in density and floats on the surface of the coffee liquid.
Milk foam is produced during the whipping process, which is low in density and floats on the surface of the milk.
When the two blend, the milk and coffee liquid sink, and the milk foam and grease float on the surface of the mixed liquid.
The process of blending high-quality oil and milk foam, due to the difference in color between the two, creates a sharp contrast,
This results in a beautiful floral pattern.
Second, the steps of pulling flowers
Deeply roasted coffee is more suitable for pulling flowers;
(1) Extract espresso:
Ground coffee: 18g
Time: 22s~30s
Extraction ratio: 1:2 (that is, 18g of coffee powder to extract 36g of coffee liquid)
PS: Different coffee handles have different bowl sizes and different amounts of use.
(2) Make milk foam:
The ingredients of milk include: fat, protein, etc.
Milk with a higher fat content will produce a better density of milk foam.
Pull the flower jar into the milk, good milk foam has a great help to the pull flower,
Milk: Generally there will be a tick line on the flower jar, pour to the tick line
Position of the steam rod when the milk is lathered: Pictured
1) First of all, the steam rod is buried in the milk (the 2 points in the picture can make the milk swirl, depending on personal habits)
2) Turn on the steam switch
3) See a whirlpool on the surface of the milk liquid
4) At this time, the flower jar is moved down to let the air roll into the milk (you will hear the sound of the second time)
5) After 2 to 3 seconds, move the flower pulling jar upwards to refine the milk (it will be refined if there is a whirlpool)
6) The temperature reaches 60-65 degrees to turn off the steam
At this time, when you shake the flower jar, you can see that there is a layer of delicate and no coarse foam hanging on the wall of the cylinder, indicating that this is an ideal milk bubble.
(3) Let the two merge:
1) The coffee cup is tilted and the milk is started (the injection position is at the middle point of the coffee liquid)
2) Control the pulling vat clockwise on the wrist so that the milk and coffee liquid are evenly integrated (the height of the latte jar and the coffee cup is about 5-8cm)
3) 4 full stops for blending into a coffee cup
(4) Start out the pattern:
1) Lower the pulling jar so that the nozzle of the pulling jar is close to the coffee liquid
2) Pour out the milk foam and let the pattern take shape
3) The flow in the coffee cup is more and more, and the coffee cup should also be slowly corrected
4) Finally, the flower jar is raised to the left and finished
How to practice pulling flowers without a coffee machine at home?
1. You can buy a small household coffee machine or a mini toy machine instead, as long as you can extract the coffee liquid or send milk foam can pull flowers. The price is probably between 500-5000.
2. Don't want to spend too much money to buy equipment, you can buy a professional milk foam machine and mocha pot, you can also make coffee flowers.
3. If you don't want to drink coffee and just want to play with the flowers, you can buy a milk bubble machine, and the coffee liquid can be replaced with chocolate sauce with water/ matcha powder with water or coffee powder (of course, coffee powder cannot be drunk) and so on.
Finally, if you want to learn coffee more professionally, it is recommended to find a professional training institution to study.
