What Is Siphon Coffee Brewing and How Does It Extract Flavor?

The siphon pot uses steam pressure and the siphon effect to brew coffee. Water in the lower chamber is heated until steam pushes it into the upper chamber, where it mixes with the grounds; as the temperature drops, the liquid returns through the vacuum tube. The result is a fuller mouthfeel and richer aroma than pour-over.

The device first appeared in Europe, and its trademark registration belonged to Frenchwoman Marie Fanny Amelne Massot, whose spherical design fixed the siphon pot's place in coffee equipment history. Reproducing a good cup at home depends on the coffee-to-water ratio, when the grounds go in, stirring technique, and judging when to cut the heat.

Indonesia occupies an important place on the global coffee map, with Java, Sumatra, Kalimantan, and Sulawesi all being well-known producing regions.

The working principle of the moka pot is to complete extraction by means of the steam pressure generated in the lower chamber (about 1.5 to 3.0 atmospheres). When the pressure is sufficient to penetrate the coffee bed, hot water is pushed up into the upper chamber; on its way up, the hot water flows through the coffee grounds in the filter and extracts the essence of the coffee at extremely high speed. The coffee liquid obtained in this way is intense with both acidity and bitterness, making it one of the devices closest to espresso.

(3) Tighten the upper and lower chambers to prevent the coffee liquid from spilling out during extraction.

(4) Place the moka pot on a small gas vaporizer stove or induction cooker to heat, first using medium heat, and after hearing a hissing sound, turn to low heat, and the coffee liquid will flow out naturally.

(5) When the sound becomes a faint bubbling sound, turn off the heat immediately to prevent over-extraction. At this point the fragrant, rich coffee is ready.
