  • Rate my shot....

    Hi,

    heres a video of my morning coffee today - Limu from a Breville 800ESR (with the unpressurised Krupps basket).   The shot tasted good, but I thought maybe the grind (from a Rocky) was a bit too fine, and the pour a bit slow (?)

    And heres a look at the puck:




    What do you think?

      The shot is too fast. The grind setting you have the rocky on looks like filter grind! That is to say, my opinion is opposite to what you are thinking. You need to grind much finer.

        I wouldnt say he needs to grind "much finer" but maybe tweak it a tad bit finer. Remember.... that machine utilizes a thermoblock and Ive never read of any thermoblock equipped machines producing perfect brew pressure. "Much finer" and he wont be pulling anything.

        Also appears to be a small amount of channeling (small hole around the 7 oclock position in the puck), which would cause the shot to pour faster than normal and also leads to quick blonding.

        BTW, I thought a Rocky would make a better looking puck than that. Even though the grind is a bit coarse it looks like too much inconsistency in particle size. Coarse around the outer edge of the puck and dust near the middle giving that smooth surface. Later!

          Just looks under-dosed to me, shown with the soggy, manky, crumbly puck when its tapped out. Looks like you didnt have enough coffee in there to have any real expanded pressure within the basket while brewing, hence the water just gushed through it producing the gusher shot and loose puck. That is there was not enough back pressure against the shower screen. I bet if you prodded the puck after the shot while still in the PF your finger would sink right into it... or at least not be hard.

          Try keeping the same grind setting (ish) and updose.

            Agreed about under dosing. Cant see any imprint left from the shower head/screen.

                The shower screen on these is concave so it is almost impossible to get good contact against. I flattened mine out which improved it a bit but still had a lot of water behind the shower screen after the shot was finished.
                I dont understand the idea behind a curved shower screen

                  Great observations team, but as David S once said thats what its all about. Ditto to the above though !

                    Hi Guys,

                    thanks for all the tips.  Yeah I think youre right with the under-dosing.    I was finding with that machine that if I filled the basket and tamped as per usual the pour was really really slow, and it was struggling to get anywhere near 30ml, or it would choke.

                    Re the imprint from the shower screen, yes it does do it and sometimes leaves behind a nice clover leaf.     For some reason the puck is always soggy if I remove the handle straight after doing the shot.  From what I read, this is a feature of the breville machine.

                    If I steam some milk after the shot while still leaving the handle in place, it dries out a bit, and produces a dryish one,  like the pics above.

                    The rocky was set to about 9 or 10 btw.   Im thinking about doing the stepless mod as Im often stuck wanting to grind in between numbers.

                    Anyway,  Ive got a few more days off work now to put the M27 back together  and play with setting that up.    Im looking forward to selling the Breville!

                    The next project is to finish off building a turbo oven roaster (got all the parts here just waiting to go).

                    And after that, a restore of an old Anfim grinder that I got for free with the M27.   It looks just like one of these (see pic), but it came missing the hopper so Ill have to get one of those.  

                    Do you think it will give a more consistent grind than the rocky?

                    cheers.

                      a modded rocky is consistent enough for your machine, i doubt you would taist the diffrence.

                        Maybe i have always been a massive overdoser? Even when I used my Ikon which had a concave screen i would always get some sort of imprint. I guess we all have our different styles........

                          i should have said that i have not seen many 51-52 group head machines leave imprints with standed doses.
