Rancilio Silvia with PID: Shot Temperature in Cup
HTML-код
- Опубликовано: 7 авг 2012
- What's the temperature differential between extraction temp and shot temp? Gail pulls shots into a room temperature and then a pre-heated shot glass to demonstrate.

Yay more rancilio videos, I ordered mine today.
Now, 7 days of waiting :(
We don't sell these outside the US, unfortunately. We use the Auber kits -- you could contact them directly to see if they are shipping them internationally. Hope that helps! - Kat
Thank you for sharing this!! - Kat
Just think of how excited you'll be when it finally arrives! :D - Kat
does the solenoid valve activate after the preinfusion stage, during the wait time, before the actual brewing begins?
I hope you find it helpful, even if there is a lot to consume! -Kaylie
I haven't experienced that in practice .... not sure -- there can sometimes be random issues with the OPV that would produce this, but in general you're looking at much higher BAR pumps that, if your grind is calibrated correctly, will extract at the 9 BAR pressure. - Kat
I noticed PID showed 211 degrees at start of shot. Isn't that about 10 degrees low?
Hi Gail. I hope you can help. I have the rancilio v3 and my boys bought me some coffee from a fancy shop that is supposed to have complex flavours (chocolate, toffee, marmalade). I’ve been watching your videos to see why the coffee tastes sour.
This is what I typically do:
1) The boiler is on for about an hour with the porta filter attached.
2) when I flush water through after an hour the temperature of the water is about 160F
3) my coffee beans are no more than a week old
4.) the beans are ground in my Ascaso mini
5) the double shot extraction is around 28 seconds with a nice thick crema
6) the coffee puck Is not too dry and and not too moist
The coffee tastes sour!
What am I doing wrong ?
Thank you! - Kat
Have you been able to measure the actual brewing temperature so you can accurately set the PID? I'm just curious exactly how much heat is getting lost from the boiler to the moment it hits the puck. I assume you'd need some kind of temperature probe inside the porta-filter to do so.
Too bad there isn't a way to get a temp probe inside the boiler itself - one positive difference in the PID on the CC1 which does have a probe inside to measure the actual water temp.
It's on our new product add list but not a high pri right now - Kat
What is the best temperature ? I heard 93°C (200°F) for the extraction. I have the rancillio silvia V3 PID retrofit. And I know that their's a difference between the outside and the inside of the boiler.But do you have a preference ? Thank you very much
Hey Kat, I read that the Silvia factory setting for pressure pump are 11 bar, which is too high for silvia...is it true?
With the factory filter basket I have to set my Rocky to 4 and I set to 2 for La Marzocco double basket in able to get non sour espresso shot, but my brewing time with the LM basket are around 35-40s >.<
Although the shot with LM is really good, rich and creamy.
Is it because the water pressure is too high on my silvia?
I don't have PID yet, but I do temp surf.
Thanks Kat!
Good vid ..really informative
Did you let the group cool down before running the next shot? Naturally, the soup will be extra warm because of this also.
Any chance of offering this with the blue PID?
I cant seem to find a PID to my Silvia in Sweden or any nearby countries:(
So i might as well buy one from you guys:)
Do you sell PID to the Silvia that i can retrofit to my machine?
Ps: love your vids so keep em coming XD
There's not a great way to measure this; I've talked with Bill Crossland extensively, and unless you drop a significant amount of money, he feels you can't measure it accurately / quickly enough to know specific temperature at the brew head. However, we know that there is about a 20F differential between the PID/boiler temp and what is at the brew head, since the PID is measuring temp on the outside of the boiler. - Kat
Best temp is dependent on the coffee you're using -- 195 - 205F is the range for coffee, and what works best will depend on the specific beans you're brewing. - Kat
Nope - every model will be a bit different and we have measured that this one performs best at around 211 - Kat
Haha - Kat
Hahaha - I know, I've read some of them ... *facepalm* .. - Kat
Heee -- I have to give her a little bit of trouble don't I?! - Kat
That machine is loud!
