Introduction to the making method of Technical Video course of Milk Bubble

First, the production of milk foam

1. Pour the milk into the milk bubble pot, and the amount should not exceed 1 / 2 of the milk bubble pot, otherwise the milk will spill over due to expansion when making the milk bubble.

2. Heat the milk to about 60 degrees, but not more than 70 degrees, otherwise the protein structure in the milk will be destroyed. Be careful! The lid and strainer cannot be heated directly. (for example, make ice foam to cool the milk below 5 degrees Celsius, of course, do not overfreeze the milk and let the milk freeze. )

3, cover the lid and the filter, quickly twitch the filter to press the air into the milk, there is no need to press to the end, because it is to pump the air into the milk, so as to act on the surface of the milk; the number of times is not too much, gently twitch about 30 times.

4. Remove the lid and strainer and scrape off the thick foam with a spoon, leaving dense hot (ice) foam.

Second, the way of flower drawing.

1. To cook Espresso, it is recommended to put the Espresso directly into the desired cup. Then hit the milk foam, after completion, if there is a thicker milk foam floating on the surface, please remove it. 2. Slowly pour the milk foam into the newly finished Espresso. When the foam is fully mixed with the Espresso, the surface will be thick, and this is the time to start drawing flowers (usually the cup is half full).

3. The beginning of the pull flower is to shake the wrist holding the flower cup from left to right, and the key point is to steadily make the wrist shake horizontally to the left and right. Please note that this action only requires the strength of the wrist, not the whole arm. When the shake is correct, the cup will begin to show white "zigzag" foam marks.

4. Gradually move the flower cup back, and reduce the range of the shaking. Finally, when you close the cup, draw a thin straight line forward and draw the stem of the leaves in the cup as the end.

One of the characteristics of a coffee tree is that its fruit can bear fruit several times a year, and another is that flowers and fruits (also known as cherries) coexist at different stages of ripening. The whole coffee harvest is swayed by the vagaries of nature. If the fruit is too ripe, the beans in it will rot. If it is not ripe enough, the beans picked will not ripen by themselves. So bean pickers often go back to the same tree several times to find ripe fruit-it takes only 2 pounds to go back and forth several times, and a typical Arabica coffee tree produces less than 5 kilograms / 11 pounds of fruit in a year. can be made into about 1 kg / 2.2 pounds of coffee beans.

Most of the coffee harvesting in the world is selected by hand, so it is a labor-intensive and seasonally intensive process. Since there are both flowers and fruits on the same branch, the index finger and thumb of the collector are the best tools for collecting ripe berries. Scraping the fruit off a whole branch by hand or using an automated harvester can't tell ripe berries from green berries.

Coffee farmers who produce low-grade coffee beans like to use labor-saving methods to harvest beans, but in this way, because the quality is not pure, it impairs the flavor of coffee and lowers the grade of coffee. The way to pick coffee beans in some parts of Africa is to shake coffee trees, shake the fruit off the ground, and pick it up from the ground before the fruit is injured and rotten. Secondary coffee is produced in most parts of Brazil, and the way to pick coffee in these areas is to pick all the leaves, flowers, overheated and astringent fruits from the branches at once, and it will take two years for such a damaged coffee tree to return to normal.
