Our Belgian Syphon (Siphon) Coffee Maker is an almost magical way to make coffee. A flame heats water that slowly travels into the other chamber. The water travels into the other chamber as it heats and lifts its container which magically extinguishes the flame on its own. As the water mixes with the coffee grounds and cools, it travels back into the first chamber where it is poured from and served. An absolutely mind-boggling display.
