Espresso Simulation Pucks ??

JHCCoffee

For insertion into a PTF basket, apparently to test impacts on pressure, flow rate and time. Or to do what?

Are these of any benefit or use?

Has anyone tried one? How did you use it? Did it help in any way? Once you calibrate with it, how do you translate that into the real espresso world?

I’ve got one @JHCCoffee. I bought it to adjust the calibration on my DE1 after taking it abroad on holiday (the pumps are calibrated to a particular voltage, and can be altered depending on location). It’s fairly easy to calibrate the DE1 as you simply match the weight and flow rate on the on-screen graph. I think they are most useful for someone with a Decent, I’m not sure how useful they would be otherwise.

Having said that, John makes an interesting point below that as well as for calibration purposes, he uses them to create infusions which is a cool idea.
