How the Belgian pot works:
The main principle of Syphon is to use the ideal gas equation: PV=nRT, under a fixed volume, heat the steam pressure of boiling water, press boiling water into the upper layer to brew coffee through a glass tube, and then cool the lower layer in a vacuum-like state to absorb the coffee already brewed in the upper layer, and filter the dregs through a filter in the middle. You can enjoy the coffee while watching the picking process, which is the charm of syphon. This method is suitable for single coffee and a small number of cups.
The usage of Belgian pot:
1. Pour hot water into the lower seat, the upper seat can be inserted obliquely into the lower seat, and then heated. This can avoid the occurrence of scalding when the water is too hot in the lower seat and then inserted into the upper seat.
two。 The blister becomes bigger, that is, straighten the upper seat.
3. After the hot water is completely raised to the upper seat, you can pour in the coffee powder that has been cooked before.
4. Gently stir the powder layer.
5. Practice smelling incense, observe changes in the powder layer, or start timing, whichever method you use, but avoid stirring all the time.
6. It's time to get the concentration, smell, or setting you want, and turn off the fire. At the same time, wipe the lower seat quickly with a wet dishcloth (evenly and quickly, do not fix the dishcloth in one place, lest the lower seat burst), so that the coffee can quickly enter the lower seat.
7. Gently shake the upper seat to pull out the lower seat.
8. Pour into the coffee cup (warm the cup in advance) and prepare to taste.
