From there you can adjust one variable at a time to get the right result. Grind setting, dose level and even tamp pressure can be adjusted to get it right, just make sure you only do one at a time. Good luck.
    Yea a little too fine.the dwell time was up at 10 seconds and a spotty stream for the first half of the pour with a slightly bitter taste in the cup.

    I have crept the grind a bit coarser but am in caffeine overdose so can't have another one lol.

      Same. I'm not strictly a ristretto only drinker but my shots do tend more on the shorter, sweeter side.

          I aim for gloopy droplets at the start that gradually merge into a single stream. My goal is the slowest pour I can get away with.
          I fined up the grind this morning to try and replicate your description, however found the taste in the cup to be bitter and smokey.

          When you pour slower like this do you stop the pour earlier so it is closer to a ristretto? as that may explain why my shot tasted so bad lol.

            Based on appearances alone I would've thought that shot would be a good one. The speed and duration looked ok to me. It possibly could've stopped sooner, not much, but based on your taste description it might've been over-extracted.
            Your technique looked to be pretty good again although I'd say distribution wasn't as good as it could've been as things were a little untidy at the start. It's a good example of how visual aids are only part of the equation. A perfect looking extraction is no good to anyone if it tastes awful. So make sure you rely more on the results on the cup and the visual cues are just things that help guide you.

              Yes I agree the results in the cup is the important bit. I just like the science behind chasing the "perfect shot" knowing full well I will never get there.

              For interests sake I am going to try and pour at the same grind but kill the shot earlier in the pour (closer to ristretto weight) and see what the results are.

                I can't comment on the build quality of a minore vs the pro500 as I have no experience with that machine. I have had a look at the pro800 and the quality of finish on the 500 is the same so that gives you an idea on the finish. The 500 has a vibe pump so it's not as quiet as a rotary, however it is probably the quietest vibe pump I have come across.

                My overall satisfaction to date is very high, and the machine is capable of far more than I am. Aesthetically the machine looks awesome on the bench. The only bit which, in my opinion isn't finished as well as the rest of the machine, is the little rail on the cup tray it just looks a bit less refined than the rest of the sheet metal work.

                I hope that helps you with your decision.
