The process of making coffee in siphon pot is invented based on the principle of thermal expansion and cold contraction.

Brief introduction of siphon pot

The siphon coffee pot, also known as the plug Pot, is made by Scottish Navy engineer Robert Naiphir. It was invented in 1840.

The siphon pot is invented based on the principle of thermal expansion and cold contraction, which produces water vapor after heating with water during production, resulting in long heat and cold shrinkage, pushing the hot water from the lower seat to the upper seat, and producing negative pressure after the lower pot cools, sucking back the water from the upper pot to get coffee.

Siphon pot purchase time is: 2 people, 3 people, 5 people, can be purchased according to their own needs.

Operation flow

1. When making a cup, add water to the coffee cup and fill the bottom seat of the siphon pot for nine minutes.

2. Be sure to dry the lower seat before starting the fire

3. Ignite the fire and assemble the upper seat

4. Insert the upper seat obliquely and observe the situation of hanging water with beads.

5. When the beads are covered with water droplets, they should be inserted into the upper seat and rise to the upper seat instead of water.

6. at this time, you should burn on the side of a small fire to ensure the temperature of the water, about 60 seconds.

7. Then grind the coffee beans according to the requirements, 20g / cup

8. Add the powder, mix and time, 40 seconds. (mixed for the first time)

9. Do the second mixing when it is 40 seconds, and remember the time from 15 to 20 seconds. On a case-by-case basis (second mixing)

10. Turn off the heat to low water (fast, 3 seconds)

11. Mix for the third time after assembly. Coffee liquid reflux

In fact, in order to use a siphon pot to make a cup of coffee, it is not a very difficult thing, mainly to pay attention to some details. Such as: visual inspection, temperature control and so on. This requires us to pay attention to what we have to do in each link from the very beginning. There is a saying that details determine success or failure. As a matter of fact, this is indeed the case. I personally think that you must brew coffee with your heart and brew all your focus, persistence, attitude, and love for him. Such a cup of coffee is good coffee, and the students I have met in the process of teaching, as long as you see that the student is not seriously making coffee, his expression, attention. I'm sure he has a lot of problems with his coffee if he doesn't put it all into making coffee.
