Siphon Coffee Pot

Siphon Coffee Pot

Coffee brewing--Equipment and supplies

In siphon coffee pots, two chambers are used to mix water and coffee grounds to brew coffee. The first chamber is filled with water. When the lower chamber is heated, vapor pressure forces the water to rise into the upper chamber. Here the vapor is mixed with the coffee grounds and condenses back into liquid form. The water, now mixed with the grounds, is pulled back down into the lower chamber (thanks to gravity and a drop in pressure, the “vacuum” effect), through a filter which sits at the bottom of the upper chamber, and the bottom chamber in turn fills with brewed coffee.
