    Re: Analyse This! Makin Maver Marte and Macap M4...

    Mmmm, wonder why they put some (dare I say it) crappy plastic tray with such a beautiful chrome beast??? Sort of akin to putting a crappy plastic tamper with a $3k espresso machine... :-?

    Okay, Ive worked up the never to put myself up for feedback. Sorry about the multiple posts for photos but I havent yet got an account on any of the photo hosting websites...

    Pic 1 - shot of pour about 10 seconds in:-

              Great pix Di,

              They look a tad quick and long to me :-?

              Was the espresso balanced on your palate or a tad outer front and tending sour? :-?

                Probably about mid to back of tongue.  Cant taste any sourness, but thats probably because the sugar does a great job of masking it (major heathen!) and, honestly, Im still enjoying it after the SB4800 crappuccinos.

                I looked at the puck (once the water had dissipated through), and the shower screen imprint was just slightly on it, so what are your thoughts - grind a bit finer, do you think?

                PS - Also forgot to credit the beans - "Urban Blend" by Talk Coffee...yum!

                  They look like mine - so ill be eager to see what others think of those shots too. Although 2 hour old popper roasted sidamo isnt really the best drop, it was better than a caffeine free day. If the espresso isnt perfect, just drown it in white stuff I say!

                  In the first five or so seconds of the pour is it a darker stream than what is in the 10sec photo?

                    I have sent an email to David Makin asking if he has a spare manual, but havent heard back as yet.
                    He will be away in Adelaide for a few days.

                    When you grind into the doser, it all seems to dump into one or two little triangles, is this correct and the way it should be?
                    Absolutely. Dosered grinders are really designed for pre-grinding the whole dosing chamber full of coffee. When you pull the lever, one "triangles" worth of coffee falls out. You can set the depth or height the triangle sits in the dosing chamber which will effect how much coffee comes out using the pre-ground method. This will allow you to adjust dose and hence allow you to dose a full handle in just 3 pulls of the lever as opposed to grinding fresh and manually dosing a handle.

                    With the Maver, I put the PF into the group head and take the lever right up to the top, pull the shot for the required time, and then take the lever right down to the bottom again.Is this correct or should I be moving the lever to the middle position and leaving it there for a couple of seconds?
                    Unless the machine is plumbed in to mains water pressure (which your machine is not capable of), just lift the lever all the way up to engage the brewing pump and all the way down to stop.

                    Finally, when I take the PF out, Im finding there is a layer of liquid on top of the puck.The puck is dry when I knock it out, but the liquid sits on top for a couple of seconds before sinking through. Is this normal?
                    The proof is in the cup. The photos you have posted look fast. How hard or soft are the pucks youre knocking out from the portafilter after brewing? If it is mushy/muddy and you can totally sink your finger in to it, you will need more coffee in the handle.

                    Try this. Dose the handle 3/4 full, tap (on portafilter fork preferably or bench) once to collapse the dose. Dose again and ever so slightly overfill the basket tap again. When using this technique it is important to be consistent in where you collapse and how hard you collapse the dose.

                    At the end of the day, a little bit of water sitting on the surface is not unusual...unless youre underdosing the handle (and a lot of water will be sitting on top) which may or maybe not the case (stick your finger in and check!)

                      Thanks David and all

                      Ive had a bit of a play in the intervening period (and gone through a serious load of beans...sorry Chris, so thankful you sent me two 500g bags!)

                      Here are some more results.

                      In a nutshell, the first shots are with the grinder set a bit finer (two turns of the micrometric adjuster) and dosed a bit higher in the basket.  Seemed to take forever to come out after preinfusion (about 10-12 seconds), so I dont think it was the best, although the coffee looked nice coming out:-

                        Yay - just worked out that we can now multiple post pictures!!!

                        Next set of pictures is a grind another about 3 turns of the Micrometric Adjuster, and as high as I would normally dose. These shorts seemed to turn out the best, but I concur to all of your advice.

                        I did try one more adjustment of the grinder, but it choked the Maver somewhat, so I backed off again.

                          10 to 12 seconds is far too long.

                          Di, you cannot adjust two variables at once. It makes it impossible to find out what caused the shot to do what. Was it the grind or was it the dose? Normally I would say dose to the ridge of the basket. This is a guideline. Shoot for this line every time and adjust the grinder accordingly. This method will work fine for most people at home. There are exceptions to this rule though (esprecially when preparing espresso commercially)!

                          Good luck.

                            Hi Di,

                            Those shots are looking pretty good. What size are the glasses? If they are a standard 60 ml or so then Id say you are pushing too much water through the beans.

                            In the first set of photos Id have been stopping the pull at the 20 second mark. I do like my rlstrettos.

                            ffND2 is showing signs of blonding (to me, at least).

                              Thanks Greg - sorry, I guess its hard to judge size when you dont have a reference point (the measurements wore off the glasses a while ago!) No, they are 2 x 30ml shot glasses but just close ups of them. Im stopping them aroud the 30ml mark or so each time.

                              The FfND ones I cut at about 25 seconds - I probably should have cut that one a bit shorter, but I was too busy taking photos to really see what was happening.

                              The FGHD ones I stopped at about 35 seconds, but - as I say - it was around 10 seconds before the coffee started coming through the grouphead after extraction.

                              Im still not getting the deep rich colour that Mal was getting, but he was using robusta in the first pictures, so maybe that comes out a lot redder, possibly?

                              I did taste test each shot glass (no sugar, blech, Ill never make being a cupper!) and could taste the different qualities of each ones but it was hard to quantify with my inexperienced pallate. The Finest Grind/Normal Dose one I used as a base to my latte, and it definitely did taste a lot smoother (less sourer?) than the one made in my original pictures that was too fast.

                              I think Im (almost) all coffeed out for the day. Will probably get one more in (No. 7) and then have to quit before I start seriously twitching...

                              Thanks so much for the tips / feedback from you all (sorry, David, I really do appreciate it since youve almost giving me an internet lesson for free today!)

                              I will keep on adjusting the grind through the week and see if I cant hit the nail on the head and post some more pics next weekend if I get it right.

                                Is the spotting (cant think of a better way to describe it) in the third last pic from the water being too hot?

                                Its a bit blurry to tell, still better than my pics though , and I think its the same problem ive been having.

                                For those in the know - and assuming boiler pressure is ok - is this fixable by flushing some water right before the shot?
