Re: Extraction quality of PID Silvia vs pointy end
Im clearly not in the same espresso league as Sparky! I cant say Ive noticed any difference in flavour in adjusting the PID temp but then Ive never sat down and done a series of logical tests. I dont actually have a problem with the taste of the shots I pull, its just that they generally have to be very short otherwise premature blonding is very likely.
Aaron: Its a bit hard to say. I changed the spouts maybe 12 months ago and its easier to pick blonding now compared to the standard Silvia spouts which would tend to mix everything up as it came into the exposed part of the spout. So I think Im being more picky and stopping shots earlier than I used to, which may also be why my wife now enjoys her lattes without sugar (rather than 2 sugars!). But either way, using the same scrutiny on Epic shots with the same spouts (which I did when I was back there recently) the pours are definitely longer before blonding, noticeably. There wasnt any noticeable difference going from the Mini to the Super Jolly, and I dont recall my own roasted beans as being particularly worse than commercial ones (unless theyre too fresh and they blond very fast). So I guess Im not aware of any significant change at my end which is why Im looking broader for solutions.
Ive never tested the pressure with a gauge, but some time ago I did do the stall test where you measure the amount of water flowing back through the return hose into the tank when the pumps on and no outlet, and it correlated exactly to the amount on the Ulka site said would be rejected at 9 bar. So it should be at least in the right ballpark. Ive not heard of the 5c coin trick, perhaps you could elaborate?

thanks to your team.
. But the Vibiemme dual PID machine would fit into my Christmas Stocking 8-)
