    My brother in law has the Mitica and I have the Pro500. He recons his has more bling and mine is more German functionality, thus the Mitica delivers much more psychosomatic varietals than mine.😕. I beg to differ.

      That's exactly what we need!! Sibling rivalry regarding the sibling rivalry!! Classic. Let the battle begin.

        ECM vs Bezzera.

        https://www.youtube.com/watch?v=rZBt7ykfI6k&t=630s

        To my untrained eyes, The things i like about the ECM over the Bezzera are all copper tubings, easier to adjust OPV, more sensible internal layout (subjective), quiet pump mounting brackets, insulated boiler, stainless steel portafilter (again subjective) etc.

          There should not be any need for a cooling flush on an HX that has been set up for the Australian market. There are a few threads discussing this if you search around.

          Cheers, Dave
          Thanks Dave. I'll search harder. I focussed my search on Bezzera machines so might widen to cooling flush non machine specific.

            Hello Symphonie,

            The machine in the link is the Bezzrera Galetea with a vibrating pump. The models we are talking about here are the ECM Tech and Mitica with rotary pump. Very different beasts in terms of OPV / rotary pump adjustment and pump mounting brackets. I am also not sure if the group handles are stainless.

            We just received an ECM Tecknika Rotary into stock today. I might lift the lid on it tomorrow and do a side by side comparison with the Mitica Rotary

            cheers

            Antony

One assumes that the chrome (by that I mean the whole external look) is largely low priority for the R&D budget, and most of the work goes on inside.
              Hi Al,

              We got an ECM Technika in stock today. Ill lift the lid and post some photos

              Cheers

                What baskets are you using?

                If stock baskets, then it's worth weighing out your doses ( if you're not already doing this ) to keep an eye out for changes and work toward what dose works best with that basket.

                I've had success with 18g VST baskets in the Bezzera double spout PF.
                G'day matth3wh. I'm using the stock baskets. Good advice on the dosing. My Rocket would take 22g, which is nowhere near enough for the BMT double basket. I've upped it to 25g and I reckon it's still not quite there as my pucks are still wet. That seems a lot of coffee to me.


                I've been messing with my tamping technique, which is probably not helping. My Rocket routine was fill the basket to level then tamp lightly with weight of tamper. Continue filling to slightly overfull then level with my finger. Tamp to 15kg pressure (using my Eazytamp). With my BMT, I've been skipping the first tamp step and just filling the basket then levelling and tamping.


                I think I'm going to go back to my original routine and just fill the basket and observe the subsequent pucks then reverse engineer the weight of beans I need to be using.


                Am I overthinking this? It shouldn't be that hard.

                  As for the wet pucks, I would look at your dose. Generally a wet puck indicates under dosing.

                  The Mitica is, IMO at the top end of home domestics. For some reason it doesn't seem to get much recognition here which is unusual when you consider how popular the newer and less established Profitec ( and to a lesser extent ECM Germany ) brands are.

                  Styling queues between the three brands should give you a little hint... rumour has it that not that long ago it was actually Bezzera who made the parts, or most of the machines for ECM (and Profitec)

                  Cheers

                  Thanks Antony. Yes, agree I need to mess with my dosing to stop the wet pucks. And yes, I also agree the Mitica doesn't get a lot of air time around here compared to the German competitors and the Giotto. I wanted a machine I could plumb (having already owned a plumbed machine). My shortlist was the ECM Technika and Giotto Rocket Evoluzione. The Mitica wasn't even on the radar as I didn't know it existed, despite having been an avid CSer for some years. It was purely the recommendation of the shop that led me to the BMT. After seeing them in the flesh and doing some more research, the BMT ticked all the boxes. Rotary pump, plumb capable, great construction and classic design. I didn't realise how much I'd love the levers. Instant and mindblowingly powerful steam. Once I dial in my technique to get consistent and repeatable shots, I reckon she'll be my 'forever' machine. I don't know how you'd ever say it lacks 'bling'. I love it.

                      Wow, it looks crowded in there! You could drive a truck through my old ECM Rocket but it had no tank. Plumb only.

Secondly: even though they may not have been fully dialed-in, how did your shots taste so far? Unless they were distinctively sour, I wouldn't worry too much.
                        Yes, definitely warmed up. Generally 30 mins at least. I'm not sure about sour. I thought my shots tasted more acidic, if that's what you mean? My chief tester (wife) thought the same. That's using the same bean going from my Rocket to the BMT. That said, I would still say the shots were good. Just different to my Rocket. I put that down to just not having quite got the machine figured out yet. It took me a while to get to that happy place with the Rocket too.

                          ECM, would be curious to know if AU spec machines are different.

                            More acidity suggests a lower brew temp on average, all else (beans, dosing, grind setting, tamp) being equal. This is not bad necessarily. "Acidity" is a feature that is valued by most coffee aficionados, "sour" usually has the negative connotation of being too acidic. It could be your BMT has been tuned differently than your previous machine such that it requires a minimum to no flush to nail the brew temperature to your liking.

                              Yes, I think you're on the money there. I saw a Youtube video where they state the machine needs very little cooling flush. Thanks for your reassurance that all is ok.

                                Is the boiler nickel plated? It's not stainless steel, right? All the specs I've read say it's copper so guessing the silver colour is a plating?
