1. Add a proper amount of purified water (heated purified water can be used,
To shorten the time of boiling water. In this operation, the amount of water added is 2.5 cups, which is about 280 ml). 2. Under the condition that the fuel in the alcohol lamp is sufficient, ignite it and place it right below the lower seat of the siphon pot.
3. Fix the screening program with filter cloth/filter paper on the upper seat of the siphon pot, and ensure that the position of the screening program is in the center (if the position is off, it can be adjusted with a bamboo stirring rod).
4. Pour a proper amount of coffee powder (2.5 cups of water corresponds to about 37 grams of coffee powder, which can be adjusted according to personal taste) into the siphon pot seat. Shake the seat a few times horizontally so that the coffee powder is evenly covered on the screening program.
5. Insert the upper seat of the siphon pot obliquely into the lower seat, but don't insert it tightly (if the upper seat is inserted after the water is boiled, the boiling hot water may suddenly gush out, which is quite dangerous).
6. After the water in the lower seat is completely boiled, move the alcohol lamp temporarily for about 10 second, and then move it back, but don't put it directly under the lower seat, it should be slightly off the center. This has two purposes: first, it can make the water temperature drop to the most suitable temperature, about 95 degrees; The second is to reduce the firepower of alcohol lamps (as I said just now, alcohol lamps are not convenient in adjusting firepower, which is why some people use two alcohol lamps or gas stoves with adjustable firepower in turn).
7. Straighten the upper seat and insert it into the lower seat (with a little force).
8. At this time, the water in the lower seat will flow into the upper seat along the riser of the upper seat due to the increased pressure after heating. When the water in the lower seat is only 1/3, pour the ground coffee powder into the upper seat and splash the wet coffee powder from all sides to the middle with a bamboo stirring rod.
9. After the coffee powder is completely wet, start timing (don't stir the coffee mixture at this time, this stage is called "stewing").
10. After about 45 seconds, quickly stir the coffee solution with a bamboo stirring rod. After a layer of foam appears on the surface of the liquid, the stirring can be stopped. Wait a few seconds, then the alcohol lamp will be removed and put out.
1 1. Wipe the lower seat with a wet rag prepared in advance to cool it down. The wiping sequence is to wipe the bottom first and then around, and don't stay in one place for too long, so as to avoid the uneven cooling of the lower seat and the explosion. If you are skilled, you can wipe the lower seat with a rag in one hand and stir the coffee solution with a stirring stick in the other hand to speed up its cooling.
12. When the lower seat is cold, the internal pressure drops, which causes the coffee solution in the upper seat to be sucked back to the lower seat (this is also the origin of the name of the siphon pot).
13. When the coffee solution in the upper seat is completely sucked back, pull out the upper seat and pour the coffee solution in the lower seat into the pre-heated coffee cup.
