Hi,
I have a question about the La Marzocco GS3 pre infusion needing to be around 4 bar. The reason that I bought the AV model because I was not plumbing in, was because the Paddle model would only reach 2 bar when pre infusing with the water tank. And I was told that this would not be enough for proper pre infusion. But people using the Vesuvius seem to be pre infusing at 2 bar. Why does the LM have to be above 2 bar?
Thanks.
