Boil water and pour into the lower globe. Compared to heating cool water over the siphon's burner, this will save time and conserve fuel. Apply heat from a butane or alcohol burner (included), fix the filter assembly, and fit the top chamber inside of the opening of the bottom bowl, ensuring a snug fit. When water begins rising into the top chamber, lower the flame (if you’re using a butane burner). Use a stirring utensil to push around the edges of the filter, minimizing large bubbles. If you have a thermometer, begin tracking the temperature at this point. Without a thermometer, a good stir on the 3-cup tabletop and 5-cup stovetop models can help steer the temperature toward proper brewing range. The 5-cup tabletop and 8-cup stovetop models should be ready to go by the time you’ve adjusted the heat and made sure that there are no air bubbles. Now grind the coffee and add it to the top chamber. starting a timer immediately. Stir the coffee in a zig-zag pattern until all the grounds are submerged. After 30 seconds, stir again. Once the timer has hit 1:00, extinguish the flame and stir one last time. Total brew time should be close to 2 minutes, including draw-down.
