    Silvias with PID or other

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi All
    A question to Silvia owners that have a PID or other Temp controller?
    What temp do you dial in and where is the temp probe locate ie top of boiler
    I am finding I am dialing up to 111c and still tasting quite smooth and wondering how high to go.
    Below 100c certainly can taste sour!
    What are your experiences

    Regards

    I tend to run mine set at 109-110 with the thermocouple mounted at the top where the stock thermostat sits.

    Hi croweater,

    Yep, same as Mark. Didnt really have a choice, as there are no fixing points around the side of the Boiler anywhere. Its probably not a bad place to put it anyway since this is where the fresh water enters the Boiler and will therefore trigger the PID more quickly than if it was placed further away.

    My setpoint range ended up on 109-111 deg.C which results in a quite stable brew water temp of 93-94 deg.C measured using a t/c and suitable DMM with the t/c bead jammed between the side of the basket and the PF just under the lip area of the PF itself. Pretty well exactly the same as Marks setpoint range.

    If you really want to get technical, Sparky has performed a number of experiments monitoring the brew water temperature stability of a number of espresso machines, including the Silvia but he measures the Brew Water Temp with a t/c bead right up on top of the coffee puck so his measurements and settings would be more accurate. If you do a search through Sparkys posts re Silvias, Im sure youll find what youre looking for.

    In the end though, it just comes down to how the coffee tastes. By dialing-in the temp setpoint a degree or two at a time until you find the point at which the brew tastes great to you, will be the final arbiter. Once you identify this setpoint, just record it for future reference with the beans you have used, roast profile, age, etc etc and then you have a starting point to use as a datum for all future brews. Thats all I did with my Mokita and it just happened to settle in around the temp setpoint range I mentioned above.

    Just have to start cupping croweater.... better make sure its an early morning exercise on a Saturday though, otherwise youll be jumping around the place like a demented ferret ;) and thats not a good thing to be doing on a Sunday evening ;D
