What Is Pre-Infusion?
Learn more about how pre-infusion can help you pull better shots of espresso with your Profitec Pro 500 PID espresso machine.
Pre-infusion is what allows a small amount of water through first, before beginning the shot. It allows this water to saturate the coffee and get the grounds equally wet. This can make the coffee extract more smoothly. Water will always take the path of least resistance. By letting the water saturate the grinds before brewing at 9 bars of pressure, this can help prevent channeling.
