The vacuum pot (also called a syphon or siphon brewer) is a fun way to make a few cups of coffee. Who doesn't appreciate an open flame and a retro chemistry lab aesthetic once in a while? Designed in the early 1800's by Loeff of Berlin, this theatrical coffee maker is a great way to finish a dinner party.
Here's how it works: The heat source (alcohol or butane burner) heats the cold water in the lower chamber, which creates pressure and forces the water up through the tube to the upper chamber. Add ground coffee, let it extract for a minute or so, then turn off the heat source. The coffee will pass through a cloth filter on its way back through the tube to the lower chamber. Remove the top chamber and pour your coffee!
