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

    Di, please take this the right way, but I believe Ive seen a great deal of shot glasses before, and Ive never seen those before - they look like a std 60ml glass, possibly 50ml glass at most. find a kitchen measure somewhere and and really confirm what amount you are pouring and marke the side of the glass with a texta in order to get really good advice (not from me mind you, but im sure itll help others if they know exactly what the pour amount is)

    As it is I reckon they look good enough to drink for me............ mine are a bit darker, but thats what i thought was a temperature thing.

    ps - im with you on the sugar thing - but all in the name of science heh.

      Thanks PB - you put the question in my mind, so I just went and put one of the glasses on the digital kitchen scales and poured 30ml of water in it going on the basis that 1ml = 1g and its definitely a 30ml glass and the 30ml mark is about where the coffee finishes (about 30mm below the very top of the glass).

      Must be just my trick photography, but I was using the zoom function so that you could see a close up of the crema and colour of the shot.

      Sorry, photographys not my forte, even though I did a term of it as a dedicated subject in high school!

      Just as an aside, I did my final 7th shot and decided to give it the micrometric adjuster a last couple of turns and pulled a shot: got a completely different taste out of the coffee altogether (not entirely pleasant, but not chronically unpleasant, if you know what I mean) and it went back to the 10-15 second pre-infusion time. Didnt sink it, although I probably should have, but I was all shot-pulling out so ended up drinking it.

      Immediately put the grinder back to where it was, so Ive obviously hit the right grind, right dose, even tamp, so now its obviously just down to how hard I tamp and whether its too hard or too soft (I suspect too hard, if anything). Or maybe grind a bit finer and tamp lighter....ah, so many variables, so little coffee tolerance after 6.00pm, damnit!

        Ummmm, Di--those numbers dont add up--30mm is more than an inch! And about where the coffee finishes--do you mean the black or the whole extraction--including crema? and in which photo?

        Remember that caffeine is very bitter, and extracts slower than the coffee flavours, so the longer the extraction, or the larger the extraction the more bitter the flavour.

        If the coffee is bitter to you, then extract shorter, or less, or both for a ristretto. Some people like bitter, others dont, and some (mostly males IIRC), cannot taste it.

        The colour of the extraction does get darker with higher temperatures, and with darker roasts.

        Keep testing--once you find YOUR sweet spot, then all will fall into place.

        I measure out 19 grams of beans, and extract less than 30 ml TOTAL for my ristretto. Mark Barun of "The Coffee Barun" has a "special" that is a triple dose, with about a 20 ml extraction total. With good beans its like dark chocolate and fruit and I easily drink it without sugar or milk (my usual is a bit of both).

          Sorry, Greg, got my measurements wrong - meant, as in 1/3 of a cm or so (3mm?). Unfortunately I put about as much effort into, if not less, maths in school than in photography - always been more of a word person than a sums person (I bet you could never guess Im a 100wpm touch typist with a propensity for gabbling on a bit too much at times!) [smiley=vrolijk_26.gif]

          And this was around where the top of the crema finished, give or take, in the last couple of final shots (ie; rounds 2 and 3).

          The very last 7th shot definitely tasted a bit on the bitter side, but shot 6 (the finer grind, normal dose) one didnt have any bitterness whatsoever, so I think it was pretty well on the nose for the most part.

          Im very susceptible to both bitter and stale which is what keeps me away from most chain coffee houses and my local On Base Cafeteria, unless I have no other choice... :P

          I can always tell bitter coffee because I add more sugar to it to mask it, and why - prior to making/grinding/roasting my own - I only used to drink 1/4 strength coffee, although at the time I didnt realise it was because the coffee was bitter but rather that I thought I didnt have any tolerance for strong coffee.

          Ahhh, the God shot - still a long way away for me, I suspect, but Im enjoying the path towards it!

            Gday Di,

            I may have missed it in your posts above but do you use any kind of cooling flush before locking in the PF and pulling the shot?

              No, not really, Ma unless Im warming up the PF because Ive forgotton to put it in and warm it up before I grindl - possibly I should, do you think?

              Apparently one of the advantages of the Maver is that you dont have to do much of a cooling flush and, I have to admit, Ive overlooked this up to now because Ive been concentrating too much on the grinding and tamping. :-[

              Ill give it a go and see how that results (in the morning now).

              Cheers
              Di

                Hi again mate,

                Yeah, I think you would need a cooling flush, be it even a small volume as the water moving slowly through the HX tube will be superheated to some extent and it is this water that you need to flush out. Chris has got a really good description of how to get the best out of E-61 Group machines at the top of this category as a Sticky. Well worth reading through..... 8-) As is this info from the Home Barista website... http://www.home-barista.com/hx-love.html

                Mal.

                  Thanks Mal - gave it a try this morning and it does make a difference: the coffee doesnt taste as burnt.  It wasnt an overwhelming flavour previously, but the two coffees Ive had so far this morning with a cooling flush are definitely a lot smoother on my pallate, thanks for reminding me of it!

                  Im at home from work with Emily (8 year old) who has a bad cold at the moment - no curly tails evident! - so Ill have plenty of opportunity to experiment today.

                  Probably the worst thing is Ill be refilling the 1.7l tank every couple of hours and, where Ive got the Maver is against the wall underneath some overhead cupboards so its a bit of a pain pulling it out so I can remove the tank to refill.  Once Chris 3 month Warranty is up, I might have to get Pete to modify it to make a hinged side opening so I can remove the hoses and slide it out sideways (if thats possible!)

                  Hey, BTW, the rumour at the moment that we might be moving up to Ipswich early next year, so I might get a chance to catch up with all my Gods Country friends (ay...   have to get back into the swing of it after being away for 10 years! )

                        Yep, Mal - at this stage, anyway...the great grey beast has been known to change its mind at a whim, however its looking pretty good at the moment...ay.

                          My Expobar is in the same position Di.
                          I cant get the tank out either, but I just use a kitchen funnel and pour into that from my Brita jug.
                          Its still a bit tight but works.

                          I dont know how yours is designed but why do you have to take the tank out to fill it?

                            Yes. Cant you just fill it from the top? I think you just have to remove the top plate, right?

                              You can just take off the warming tray but its only got about a 4cm diametre hole to fill into which still means that I either have to have the jug very low with the water level in order not to tip it all over the machine from the front (not to mention I cant really see it that well), or I still have to move the machine away from the wall on an angle so I can get in from the back - theres probably only about 10cm gap between the top of the machine to the bottom of the cupboards, so not really enough clearance for much at all.

                              I really dont see it as a design fault really, just more of an inconvenience with where I have placed the machine. If I wanted to, I could move the machine to the island bench but it all just fits so nicely (well, apart from the lack of clearance above) in the area that it is with the grinder, knockbox and canisters and its also in a bit safer area where it cant be touched by little 3 year old fingers.

                              Actually, thinking about it, Id probably be better off getting Pete to build me a  plate to go underneath it so I can slide it more, because at the moment I have to lift it off its feet to move it and its a heavy little bugger!  Hmmm, more things for Pete to build me!!!  I put in an order today for a custom made plate to fit underneath the grinder, so hes not going to be particularly enamoured with me at the moment...

                              Best thing he did was become a metalworker/welder (well, for me, anyway!) and gain enough of an interest in it to buy the bits to be able to do homework at home!

                                I use a clear hose connected (pushed in) to the Filtered water tap to fill up the tank
