Siphon Coffee
虹吸咖啡
Brewing MethodsDefinition
A vacuum brewer made of two stacked glass vessels: vapor pressure pushes water from the lower globe into the upper chamber, where it mixes with the grounds, and once the heat is removed the cooling lower chamber forms a vacuum that draws the brewed coffee back down through a cloth or metal filter. The result is a clean, tea-like cup, and the visible brewing cycle is part of the appeal.
Etymology
The vacuum principle was demonstrated in the 1830s and refined by inventors in France and Scotland, but the design found its lasting home in Japan, where it survives as siphon coffee and is usually heated by halogen lamp or butane burner.
In use
Cafés keep siphons for tableside service, so saying a coffee is brewed on the siphon signals a premium, single-origin presentation.
