Some of you struggle to understand why i hold the home barista website in such low regard as a source of reliable information for lever espresso machines

I give you Exhibit A:

Reiss,

Thank you for the clarification.

hi dan

i was reading your review of the Profitec 800 and read the following;

Notice that Dritan doesn't really bother with preinfusion time. It proves the old adage that when it comes to lever espresso machine usage, there are no rules, only suggestions.

i think you will find the reason for this is the groups on his machine are TS/HX fed (as opposed to dipper fed) and therefore he is pre-infusing at line pressure (typically 3 bar, but possibly higher if he has not regulated the water line), not boiler pressure as you are using on Profitec

as a result the pre-infusion phase completes much more quickly for Dritan, rather than it being true that you can pre-infuse any old way you please

Kind regards

too proud to change what they have written though because that would mean losing face

the notion that there are strict & precise rules for the correct operation of a pump driven espresso machine, yet you can use a lever machine in any fashion you please is laughable i think.
