    With Antony on this one. Stock shower screen and basket should be perfectly adequate for a few years especially during the learning phase. Then if happy no need to upgrade. The VST baskets can be more difficult to work with if your dose, grind and tamp arent perfect.

    Standard tampers are usually crap though so an upgrade from a plastic tamper is definitely worthwhile.

    To be honest the short list would be (budget of around ~$1500):

    * BDB (not super keen due to appliance style)
    * Oscar II (simple design, minimal electronics)
    * DE1 (similar concerns regarding reliability, but seems like the essentials for good coffee will be solid)
    * second hand machine (Rocket, Bezzera etc)

    Oscar sounds like it will tick all the boxes. My friend essentially is looking for something with more steam power for when they have visitors. The coffee geek in me wants to ensure the shots being pulled are at the right temp and no surfing required
    All machines with merit.

    Although the DE1 looks a little out of place to me in this group. Its going to be a great machine when it comes to market but I would think would attract a different sort of user to someone looking at Breville DB or Oscar II.

    As for the hissing dragon, these days all good HX machines don't need the fabled cooling flush. In days gone by with hot running Italian spec machines yes, but not now.

    Cheers

    The square nut definitely does undo.

    A bit of force is OK, we regularly use a shifter on the group handle spouts and handle....

    any chance of sharing your routine of using machine?
    im getting some bitterness I'm my shots, get 60ml in 27-30 seconds, tamp has finished puck level with ridge line on NS double basket and coffee starts to exit portafilter spouts around 14-16 seconds after pushing double button. Tried changing grind a round but bitterness still there. Tried a cooling flush but not helping.

    any ideas to improve shots? Nice in milk not great as espresso.

    Ok,

    If you can send me a clip of your extraction it will help

    Generally speaking bitterness comes from the coffee or under extracted shots (ie when the coffee is flowing too fast/ grind two course or under dosed)

    A burnt taste will be when the flow through the coffee is too slow or too hot,

    Your dose level seems right.

    Is the coffee freshly ground? what is the coffee? What is the flow like through the group head?

    Feel free to call me if required

    Cheers

    You might have have a few things going on there. Your dwell time is long and the flow/volume sounds too quick. I think you're too fine in grind, underdosed, and getting some channeling. I have seen this before in the Simonelli basket on the old Oscar. When you hit the sweet spot all will be good. I'm sure Casa can help you after seeing a quick vid.

    Flow time definitely seems quick for the volume. Under extraction = biterness

    Chris has nailed it i think. Coarsen your grind, Aim for 5 seconds before you see coffee and 50-60ml in 30 ish seconds.

    Hi gang, I have been doing some research for about 2 weeks now and have found this forum to be outstanding with its wealth of knowledge and advice. I am considering the Oscar but have a question regarding the power consumption. With the 2L boiler, is it expensive to run, how long does it take to warm up? The machine would only be making 2 latte's a day ( maybe 4 on the weekends).
    Cheers in advance

    Hi Shane.
    A while back a forum member did some calculations. For a 2L boiler, initial heat up costs of 20-30c and idling costs of approx 10-15c per hour would be ballpark figures. Nothing to worry about
    Use the search function to see if you can find the old thread.

    Hi Trentski

    when you sayaim for 5 seconds before you see coffee do you mean from when button is pushed or after pump kicks in after preinfusion phase?

    It not a big big difference but wanted to check.

    thanks

    Thanks everyone for the help I'm starting to get better shots, refining my dosing. Got a set of scales coming so I can be more consistent while learning as having issues adjusting the grind and getting dose consistence.
    not sure if it's something that matters but when I find my Stainless screw collection I'll change the shower screen screw over to a countersunk one as noticed that the bolt head leaves a big indent / hole in the coffee puck before I pull a shot as sits so far below the screen.
    beans were 4 weeks old mocopan beans now 6 weeks old, got new beans from online supplier (Costa Rica Tarrazu) but they were roasted Tuesday so think are a bit fresh still.

    Hi Martin,
    Expect coffee 6-7 seconds after hitting the button. Start timing from the moment you hit the button of course. For more info on timing see step 10 of my espresso workflow here: www.kbean.com.au/training/
    Please share a vid of one of your extractions some time. That's always good.
    Cheers, Paul

    Oscar II

    They look good together on the bench. Just add some quality fresh roasted coffee and it's coffee bliss
    Enjoy!

    If you're starting out I highly recommend a Pallo grouphead brush for quick cleaning after making your coffees.
    It and the blank filter basket supplied with your machine helps your machine stay cleaner and coffee tasting great day after day.

    Hello all,

    We have had our hands on the Oscar II for a few months now and it performs really well straight out of the box.
    http://www.casaespresso.com.au/domes...simonelli.html

    There are a few small things that we have improved on from factory that we have offered our customers.

    One thing we have been working on is our own proprietary OPV kit. This kit will allow the user fine tuning of their extraction pressure. Whilst its not a necessity it will just make this machine a little bit more user friendly.

    In the previous model Oscar we used to fit an "anti vac valve" to almost everyone that went out the door. Now the Oscar II has an anti vac valve as standard.... maybe in the future the OPV will be standard from the factory.

    We will of course be offering full factory warranty on any machine fitted with our OPV.

    Cheers

    Hi Anthony

    You meantion a few small things apart from the OPV are you able to let us know what the other improvements are?

    Can the OPV be supplied as a kit so can be DIY installed?

    Yes we are designing the OPV kit as an item that can be installed DIY. It will come with instructions on how to do this.

    I will send you a PM with the other things we do......

    Hello all,

    We have had a few people ask about OPV kits for the Oscar II.

    We now have our kit available and ready to go. Can be self installed relatively easily (instructions supplied) or can be done by your local friendly coffee tech.

    Feel free to call or PM for details

    Cheers
