Step 1, pour hot water into the ball under the glass, bring it to a boil over high heat and wait for the water to boil.

When boiling one cup, add 200 ml of water under the ball, 175 ml when not pouring bottom water, and 350 ml when boiling two cups. After pouring water, wipe the ball under the glass with a dishcloth, otherwise it is easy to break the glass.

Step 2, load the filter into the ball.

Take the filter out of the water and press it dry, hook the filter hook to the bottom of the ball, and then use the adjusting rod to adjust the position of the filter to the middle position.

Step 3, after the water boils, insert the upper ball into the lower ball.

Turn it into a small fire, carefully tilt the ball on the glass into the lower ball, and make sure that the water will not roll too much and spray out, press the ball on the glass slightly straight down and rotate at the same time.

Step 4, add coffee powder after the water rises by half, start stirring, and start timing after stirring.

The amount of each cup is 15 grams, and start the first time of stirring, do not stir around the circle, should draw 3/4 yuan around, press the powder into the water from top to bottom, so that the forces of two different directions collide with each other, do not stir too long, just spread the coffee powder.

Stir for the second time at step 5 and 25 seconds.

Stir for the third time in step 6 and 55 seconds, and turn off the heat in 60 seconds.

When it takes only 50 seconds to brew a cup of coffee (the second time in 20 seconds and the third time in 45 seconds), pull up the upper ball quickly after turning off the heat, pour out the remaining water from the lower ball, and then insert it back into the upper ball. this action is called inverted bottom water. if you don't want to do this step, the water is only 175 grams.

It is usually equipped with a boiler to generate hot water, which is pressurized to about 9 atmospheric pressure and then flows through the powdered coffee beans in the metal filter to brew the coffee. The coffee brewed by this pressurized hot water is thicker and has emulsified oil, often called espresso or espresso. There are many kinds of Italian coffee machines. For general commercial use, the most common ones are single boilers, and then there are double boilers and multiple boilers. Of course, the price also becomes more expensive, in addition to the general electronic control switch, there is also a pull-out Italian coffee machine, each has its own advantages.
