  • Silvia grind pickiness

    I'm not sure if I can isolate anything particular with my technique, but:

    combo A: expobar megacrem + compak K8 + random basket
    combo B: silvia + compak K3 + VST

    using a naked pf on each machine.

    with combo A, I can make a passable double ristretto pretty much every time. with combo B, it either gushes or starts to choke - if I have it on the choking side, the ristretto is pretty good, but there is significant flow from the OPV back into the tank. with a nudge on the grind adjustment it can make a reasonable normale espresso.

    does this mean I need to back off the OPV and increase the pressure? should I try measuring the 30 second output from the OPV to do it properly?

    Have you read through this thread? May be something in there that can help.

      I really don't think there is an issue with the Silvia + VST basket.. I used the VST on the Silvia a lot.

      Never had an issue, except when I didn't pay attention to the dosage! My grinder is/was a Macap M4 - and the compak is comparable. So it must be technique. Haven't had the Silvia for a few years now, but I do recall some issues with dosage till I dialled it in. Significant flow from the OPV though - is the pressure set at 9bar? On mine it was more like 11 when I got it - setting it to 9 did increase the recirc to the tank a fair bit!

      Keep trying! Maybe down-dose a fraction? I used the level with the top of basket and tamp...

        I tried the expobar with a single basket today - I've never made a single this good before. i don't know what it is... the machine is just so forgiving of technique (eg I levelled but I used my finger rather than a knife, and so the surface wasn't perfectly smooth).

          I have an Expobar Minore right now... I find it is very forgiving too - unless you put stupid amounts of coffee in the basket or grind for Turkish!

          Even the shots that tend to rush a bit are still quite good. Not perfect (of course) but quite drinkable. But when you nail it

          Miss Silvia is definitely a bit more picky, but not overly so. I never had much of an issue - once I got it close. But she did seem to choke more easily than the Expobar. Don't understand why that would be so though. Does yours have the adjustable OPV? (Miss SIlvia!)

            Hardly comparing apples with apples here people, Silvia an $800 machine up against an Expobar Megacrem @ over $3000 and a Minore $2700.
            Is there a reason for you to suspect a problem with the OPV on your Silvia Hildy?

              well, it was $500 machine (silvia) vs 1k machine (megacrem, used). but the megacrem is even more forgiving than a giotto.

              There is no reason to suspect a problem with the OPV, other than I have more recirculation than I would expect - but I have no experience on a silvia-class machine to compare to.

                Regardless, it might be worth swapping the baskets over between the two machines and see what difference (if any) it makes.
