Learn how to use preinfusion on the Rocket Espresso Giotto Type V.

What is Preinfusion?

Pre-infusion is what allows a small amount of water through first, before beginning the shot. You can think of preinfusion as a special trick to help bring out the best flavor in your coffee just before extraction. The idea is to softly wet the grounds before pressure is exerted by the pump. 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. Follow the steps below, and watch the video at the end of this article for more information on preinfusion.

  1. Bring the brew lever to a 45 degree angle. You will feel it stop there.
  2. Lift the lever slightly higher. This will allow for water to flow, but with no pressure from the pump.
  3. Lift the lever fully when satisfied and you're ready to brew.
