• Fill the lower chamber of the siphon with hot water and place it on a heat source.

• Attach the top chamber securely, and as the water heats, it will rise into the top chamber.

• Add medium-ground coffee to the top chamber and stir gently.

• Allow the coffee to steep for 1-2 minutes.

• Remove the heat source, and as the pressure equalizes, the brewed coffee will be drawn back into the lower chamber.

• Once all coffee has transferred back down, separate the chambers and serve.
