What Is Pre-Infusion?
If you’re wondering what pre-infusion is and how it can benefit your espresso shots on your Profitec Pro 600, our video below goes in-depth on how you can use it to improve your extractions.
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.
