The Syphon (vacuum pot) works by heating and cooling the water gases (vapour) from the lower vessel (carafe chamber) to the upper vessel (infusion chamber) and back again as brewed coffee to the carafe chamber.
Drop the filter in the top chamber such as the chain attached to the filter hangs from the tube of the chamber and then pull the chain and hook the filter to the edge of the tube.
Add the preheated water to the glass pot.
Place the top chamber onto the glass pot and twist it to make sure that the top chamber is firmly attached to the glass pot and then place the lid at the top.
Fire up the cotton wick to light the lamp with alcohol added to it as the fuel. You may also use a burner instead.
Place the lamp below the glass pot so that the water will start boiling through the heat of the lamp.
Wait till the water boils and completely moves to the top chamber.
While the water is still in the top chamber, open the lid, add coffee to the water, gently stir the mixture to ensure that all the coffee grounds are wet and then place the lid back on top.
Wait for the coffee to brew.
Put out the flame of the lamp and place it aside. Wait for the coffee to completely drain down into the glass pot and then remove the top chamber using a cloth.
Pour the brewed coffee into a cup and enjoy your hot brew!
