Preparing coffee on a siphon may look complicated, but it's not! Preparation on the Hario siphon is very easy, as it works according to basic physical laws. Fill the lower container with water, the water heats up and flows through the pipe into the upper container and onto the ground coffee. After a few minutes, turn off the water heating and stir the coffee. Put the water heater aside and drop the coffee back into the lower container.
