    Re: Silvia portafilter - correct angle when locked

    Greg,
    For what its worth - I never really could lock to 6 oclock without serious strain and a bit of an under dose - even when new.
    I recall that 7 was closer to normal.

    I also used the
    LM double as my standard for the last year or so. I think you might have one of them around.

    As Robster said - it is a learning curve, but you will get there.

    Brett.

      Greg- this can be overcome by purchasing a 7mm rather than 8 or 8.5mm gasket...

      Have a chat to Pedro at Coffeeparts

        Greg, the often referred to standard of 14 grams, from my experience, will not produce a good 60 ml double.

        The quantity is insufficient to produce tasty, viscous coffee with a good oily mouthfeel.

        No wonder you are producing gushers. The standard Silvia 14 gram double basket will take anything up to 20 grams of finely ground coffee. I find anything under 17 grams is underdosed and unacceptable.

        If you want instant improvement, try between 17 and 20 grams. The pour may be slightly over 25 secs, even over 30 secs, but youll see and taste the difference.

        With that quantity, the portafilter should still go on and lock on without undue force.

        Good lcuk,
        Robusto

          Thanks guys. Ill measure the new gasket Ive got ready to install and will get an alternative if necessary. Im presently working on 14g of beans and adjusting the grind. Initially I had the grind set for what I use on the Napoletana, filled to the brim, levelled and tamped and was getting the gushers. Once Ive found a grind/weight combination that works, Ill try taking the grind a bit coarser and increasing the quantity.

            Greg- I suggest that you bench tap to get a good fill for the Silvia (be absolutely consistent in what you do)- I get at least 18g into the deeper basket (closer to 21 when I dose and collapse). If youre using the standard thimble that the SIlvia ships with, ditch it!...

            More coffee, coarser grind, nice dry puck and slow pour is often the way to go

              Yeah Ive got a LM double to play with but I figured Id try to get a good benchmark with the standard baskets before changing things. I dose, tap 2x, dose, level with finger, tamp. Im presently only getting about 14-16g in the basket so maybe I need to go finer still. Trouble is I only make 1 or 2 coffees a day so it takes a while to work through the adjustments! Pucks are still pretty wet.

                Try:

                dose, tap, fill, level, settle off with just the mass of a good weighty tamper (sure you must have one sitting around somewhere :P), refill, level, tamp...
