Even for pump machines, the quoted 9 bar pressure is generally not meant to be the group head pressure. It is the design pressure produced by the pump. Along the narrow passages on the way to the group head, the pressure drops. 9 bar at the pump are intended to produce approximately 8 bar above the puck.
@@bellingdog On mine, 9 bars is an insane amount of pressure and I didn't like the taste at all. Actually 5-6 bars is pretty nice and it still does take about 25 sec to get about 30 ml from a 15g dose.
Steve, greetings to you and Ute. Thanks for a great video again. I have a LP Esperto Abile with a factory PPK set-up. I tend to favor and use classic Southern Italian or Sicilian medium to darker roasts for my espressos. Much like you do in your experience, I have found that I prefer my pulls to be in the range of 5 to 7 bar maximum, and which I find deliver the sweeter espressos. I rarely ever go higher than 7 bar, and now never use pulls at 9 bar. I find myself frequently doing natural, comfortable pulls, much like you, without even looking at the PPK gauge. The proof is in my cup with repeatable by feel, tasty naturally lower pressure pulled espressos. So I agree with you, these machines really were optimized for lower pressure espressos not like pump E61 machines which are designed to work at 9 bar. Thanks again, cheers.
Hey, what's your 3rd gauge you have there on the fiemrst LP with a PPK fitted (appears to be above the boiler pressure gauge). You referred to it but didn't elucidate? Secondly, what's with all the steam leakage on both machines as they come up to pressure. You need to service both so that they give steam only where and when it is wanted. Most odd.
Just for Looks i like to have two pressure gauges for a little steam punk look . On the two switch the steam comes from the pressure relief that regulates the temp and pressure . They operate with a high II for steaming and bringing up to pressure . Once there down to I and the right pressure for espresso . They operate in that simple way like a steam engine . Once finished with the pull turn off as these style of machine are not to be left on . :)
The two on the sight glass are both Pressure gauges , I just like the look of two , semi steam punk . :) The third is a pressure gauge that was on the ppk that I removed . I got caught up in the PPK fad like many . I found that they really did not add anything to the operation . :)

What pressure should ypu be aiming for with this profile kit? I usually use light roast, and have no idea which bar pressure I should be aiming for.

Excelent!!!
Great reckoning with 15-16 bars! How do you bring it up to pressure suddenly? Mod?
Edit out some of the heat up time :)
Three gauges? The final one is a thermometer? Where does one get that? Never seen it before, everyone just uses the strips or the battery ones.
